How to Prevent Damage and Reduce Wear on Your
Fine Jewelry
Whenever a ring or piece of fine jewelry is worn, wear will occur. The more
frequently it is worn, the more quickly it will wear. Periodic maintenance is
required on all jewelry to restore and rebuild worn and damaged parts. Prior to
the 1970's, rings were primarily set with diamonds mounted into recessed
settings which afforded a high level of protection. As the 1970's progressed,
styles changed with the re-emergence of prong type settings, a more delicate,
open, airy design. This change in jewelry styles occurred at the same time women
were becoming increasingly active. These jewelry designs and life style changes
have resulted in a higher vulnerability to wear and damage.
Following is a list of common causes of wear and damage to jewelry and
specific recommendations on things you can do to extend the life of your
settings and protect your gems.
Rings Should Be Removed During the
Following Activities
Gardening... Gold has a hardness of 2 1/2, slightly harder than a
fingernail. Soil is composed of particles which have a hardness of 7 and harder,
which will wear away molecules of gold rapidly. Gloves don't protect against
this type of wear. In fact, small particles of dirt inside of the glove will
wear prongs and ring shanks even more quickly. The hardness of garden soil will
also scratch and abrade many colored gems.
General Yardwork... Even though you wear gloves, it doesn't protect a
ring from bumping against a stone wall and bending a prong. An accident that
might occur in a split second could bend or break a prong, causing the loss of a
gem worth hundreds or thousands of dollars.
Housework... Imagine cleaning out a cast iron radiator and reaching
from beneath to remove a stuck toy. Catching a prong or prongs may seriously
damage or destroy a mounting worth hundreds of dollars. Additionally, cleaning
out the attic or garage, even making beds can cause damage. Wearing gem set
jewelry while doing housework should be avoided.
Working in the Kitchen... A kitchen can seem an innocent place to wear
a ring, but it is one of the situations where a woman's hands are the most
active. One bump against a metal grate in a stove or hit on the edge of a frying
pan, can cause a prong to be bent or broken, or a diamond to be chipped, or a
colored gem to be scratched. Ask for a free Cross Kitchen Ring Hook, a safe
place for your ring while working in the kitchen.
Sporting Activities... While participating in any of the following:
golf, baseball, racquetball, snorkeling, scuba diving, horseback riding, camping,
mountain climbing, rowing, chopping wood and similar physical activities, rings
and other fine jewelry should be removed. There are too many opportunities for
an accident to occur in a split second, which could cause hundreds or thousands
of dollars in damage.
Beach... Beaches contain a multitude of perils for rings and fine
jewelry. First of all, it is one of the most common places for jewelry to become
lost. Hands become cold in our icy Atlantic waters, fingers shrink and rings
easily slip off. Necklaces, earrings and bracelets are easily lost in the sand.
The greatest risk to gem set jewelry is abrasion from the sand. Typical beach
sand in the northeastern United States has a hardness of 7-8, and can act like a
coarse sandpaper on gold and colored gems. Building one large sand castle can
put more wear on a ring than a year of normal use.
Work... Your place of employment could be very hazardous to the safety
and longevity of your fine jewelry. Obviously, any job involving machinery or
moving hard solid objects, gem-set jewelry should be removed. Any occupation in
which a gem or mounting might come in contact with hard objects presents a
possible risk.
Fabric... Many years ago, we reset a family diamond into a 6 prong
solitaire for a woman who worked in a local department store's yardgood
department measuring fabric. Within 60 days she was back, holding her diamond in
one hand and her new mounting in the other hand. The prongs holding the diamond
had completely worn off. Upon discussion we learned that when she measured
fabric, she would set her left hand on the counter and pull the fabric from the
bolts across her hand. Molecule by molecule the gold was slowly but repeatedly,
all day long, being pulled from the surface of the prongs until they were worn
flat.
Another example of wear caused by contact with fabric: A woman requested we
attach an adjustable shank to enable her to wear her ring. Six months later she
returned for a cleaning and safety examination. The tips holding the diamond
were worn flat, the shank was wafer thin. The ring appeared to have 20 years of
wear. Questioning her, we learned that she made beds at a local hotel. Tucking
sheets in, dozens of times a day, had accelerated the wear on her ring.
Sleep... Certainly it would seem that wearing rings and jewelry to bed
would be safe, and yet prongs on rings can wear out in half the time if worn at
night. How? Gold against fabric. Time lapse photography shows that most people
move hundreds of times during the night while they sleep. A few molecules of
gold here, a few molecules of gold there, multiplied times hundreds of nights
over the years, represent a considerable acceleration of wear on your fine
jewelry. This wear can be substantially increased if the bed sheets include even
the slightest trace of a cosmetic, which is often comprised of microscopic
substances possessing a hardness of 7 or more. These substances act like fine
sandpaper against gold, causing accelerated wear. All jewelry should be removed
prior to going to bed.
Other Considerations Regarding Rings
Applause... To the owner of fine jewelry, one of the most baffling
types of damage to rings can occur while attending a large concert or symphony
production. In the midst of deafening applause, which often follows a great
performance, rings worn on opposite hands can literally be pummeled with hundred
of little flattened spots. Even more serious damage can occur to gem-set rings
from applause when gems in rings on opposite hands come in contact with one
another. Prongs can be flattened and bent, gems can be chipped and destroyed. In
the darkened performance hall with deafening applause, you can neither see nor
hear what is happening to your rings. Applause damage is often one of the most
mysterious forms of damage. The solution: When wearing rings on opposite hands,
applaud with the fingers of the right hand striking the palm of the left hand.
Loose Fitting Rings... No finger has one perfect size for fitting rings. Time
of day, temperature, humidity, physical activity, weight gain or loss, all
contribute to as much as a size or two difference in some people. This, in
combination with enlarged knuckles, can cause rings to fit loosely. Rings should
be made as small as possible to provide a snug fit. If enlarged knuckles prevent
snug fitting, adjustable shanks or special fitting devices should be considered
to reduce turning. When two rings are worn on the same hand together, wear will
occur as the rings rub against one another. If the rings fit loosely, the wear
will be accelerated. Diamond wedding and engagement rings set with diamonds with
exposed edges, should be soldered together to prevent twisting and turning, and
reduce the risk of diamonds damaging one another. It is best not to wear gem-set
rings on adjacent fingers, as two gems coming in contact with one another can
become scratched.
Handshaking... Women are shaking hands with men more often during the last
twenty years… a form of greeting, departure or closing a deal. The delicate
designs of women's rings can literally be squeezed out of round by a firm
handshake. Gems can be loosened and lost. The solution: Avoid shaking hands with
people who are known to have too firm a grip. If you get caught, check to be
sure gems are still secure.
Active Life Styles Result
in Accelerated Wear.
Shoes wear with use. Tires wear with increased mileage, and yet people often
seem surprised that jewelry worn 24 hours a day can show significant signs of
wear within a few years. In any activity in which the upper surface of a gem-set
ring comes in contact with anything, wear is occurring. It may only be the
removal of a few molecules at a time, but wear is occurring. Multiplied times
days, months and years, the wear may progress slowly or more quickly. Depending
on how active a person you are, daily abrasion is removing molecules of gold and
may be wearing your ring out. How and when you wear your jewelry is a personal
choice. Many people desire to wear their jewelry all the time. It needs to be
clearly understood that doing so will shorten the time between necessary
maintenance, or even require replacement of mountings or of gems, which can be
lost from settings.
The Gold, Mercury, Chlorine Dilemma
Although gold is impervious to
attack from almost all chemical substances, there are two risks of which you
should be aware. Mercury is a liquid metal at room temperature. Each year we see
several cases of mercury absorption by gold. It causes the yellow metal to turn
to a frosty white color. If mercury is not removed immediately, the gold can
become brittle and shatter like glass. The common locations to come in contact
with mercury are hospitals, doctors and dentists offices, or a broken
thermometer at home. Often the person wearing the ring infected with mercury has
no knowledge of where they came in contact with the element.
Chlorine, a chemical found in some
household cleaning agents and found as an additive in swimming pools, can attack
the alloys mixed with karat gold. Prolonged contact will cause pitting and
discoloration and ultimately a weakening of the gold in the affected jewelry.
Gold's property of malleability allows it to be crafted into extraordinarily
intricate designs. However, because of gold's malleability, even the strongest
prong can be bent without you being aware of it occurring. A common example is
sitting on the floor and pushing with your hands in the direction of the floor.
As you push off, you can easily exert over 100 pounds of pressure against a
single prong causing it to bend. This can happen so easily you may never be
aware of when or how it occurred.
Gems are among some of the hardest substances on earth, born in fire and
intense heat, surviving millions of years in the earth since their formation;
and yet all gems, including the hardest - diamond, are subject to wear and
damage.
Precautions must be taken to safeguard these precious gems from situations
which can cause damage or accelerated wear. Gems, both in storage and while
wearing, must be prevented from touching one another. For storage we recommend a
jewelry box with assigned storage spaces for each piece of jewelry, or tiny
transparent zip lock bags, which provide an excellent means of protecting fine
gems and jewelry.
Wear Will Occur
Even with taking all precautions discussed, wear will occur on jewelry with
the passage of time. This is natural. Precious metals will develop a patina
(microscopic scratches and dings in the surface). It is part of the character a
piece naturally acquires. Gems also will show microscopic abrasion on facet
junctions. Even diamonds, the hardest substance known to man, are subject to
minor nicking on the outer perimeter. Rarely do we see a 100-year old diamond
free of microscopic nicks. Wear is a consequence of use. We encourage owners of
fine jewelry to use and enjoy their jewelry, but to be aware of the limitations
of specific gems, and the care your design selection may require.
If a problem occurs with a piece of jewelry we have created or sold, we first
examine it to see if there is any structural reason that could cause the
problem, which we would take care of at no charge. Wear which requires
restoration work is part of the necessary expected maintenance of a piece of
jewelry, the cost of which is the responsibility of the owner. Damage, which is
a separate issue from wear, may be covered by the owner's insurance, subject to
policy limitations and deductibles. For these risks there is no substitute for
quality insurance. As with anything else you purchase, there are different
qualities of insurance. Be sure to ask questions of your agent regarding the
type and extent of your coverage, including deductibles and other options
available for loss, theft and damage, at home and away. Ask your agent if you
will receive the full replacement value on an insured piece in the event of a
loss, or if the company offers only partial replacement value (a type of
coverage, and company to avoid). A quality insurance company will offer
replacement at the insured value.
Enjoy and Wear Your
Rings
As a balance to all of our cautions, you need to weigh your desire to wear
your ring. If a solitaire mounting costs $350 and you wear it out in ten years,
it has cost only $35.00 per year. If you have your ring cleaned and checked
periodically you can manage the wear appropriately and know when to make the
decision to replace the mounting. Understanding how you are wearing your ring
and what the consequences of that wear are, are the keys to your success. We
want you to wear your jewelry and enjoy it. We hope this information helps you
enjoy your fine jewelry for a lifetime.
Finally, we have developed a series of rings which we have specifically
designed for changing life styles. These rings are practical and wearable. Ask
us, we'll be pleased to show you our newest designs.

Gem Durability Guide
Important Information to Help You Decide Appropriate Ring Styles
to Match Your Lifestyle and Intended Wear.
Gem Durability
This is a simple guide which combines hardness and toughness
for an overall durability rating. This presumes all gems to be free of risky
flaws or fractures. If an otherwise hard gem poses a higher risk flaw, it will
be given the appropriate durability rating. "No gem is indestructible if
hit hard enough."
- Hardest, Most Durable
-
Diamond. Extremely resistant to facet abrasion. Diamonds can chip however,
if edges are bumped.
- Good Hardness, Good Durability
- All ruby, sapphire and spinel, jadeite jade, chrysoberyl.
Quite hard, usually many years before any facet abrasion begins to show.
- Reasonably Hard, Good Durability
-
Tourmaline, amethyst, all quartz, crypto-crystalline and agate-like
material. Lapis Lazuli, garnet, aquamarine, andalucite, nephrite jade,
garnet (Emerald, very clear, untreated). Gems will wear well It is normal
for facet abrasion to show with the passage of time.
- Wearable, but having durability issues
-
Topaz, turquoise, peridot, kunzite, tanzanite, zircon, malachite, iolite,
emerald (by reputation of treatment.) Moderate wear, can expect facet
abrasion and surface scuffing.
- Very Delicate -
Opal,
pearl, moonstone, intarsias, fluorite, diopside, some highly included
emeralds. Limited wear.
For more detailed information on any gem you may be considering, we will be
happy to provide you with a copy of in-depth information sheets.

An A-F Rating System for
Mounting Durability
Following is a rating system (A-F) for new gem-set rings. This is a guide
to help you make appropriate choices to match proper designs with the
contemporary lifestyles. Jewelry design and techniques of construction can be
likened to clothing and the various fabrics from which clothing is
constructed. It is obvious the type of clothing which is appropriate to wear
while skiing, mountain climbing, gardening, as a spectator for a sports event,
to the office or to the opera. In a similar way, various design techniques in
jewelry affect the appropriateness of wear.
This A-F rating system only considers the security or delicacy of the
setting. The toughness, durability, and practicality of the gems themselves
are examined on page nine using numbers 1-5. The letter and number combined
give guidance for overall performance expectations and can assist in
appropriate choices.

A
Construction &
Durability
Very Practical
Gem
perimeter completely encircled with gold or platinum. Gem's edges are
protected from bumping or damage. Example: Full bezel or burnish-setting. Some
channel-set work.
Expectations & Limitations
These rings can be worn during the widest range of activities. Provided
the original bearing is cut properly, the gem is correctly seated, and a
sufficient amount of gold or platinum is secured over the edge, the gem will
remain the most secure of any of the common setting techniques. An
"A" ring can be worn during almost all business and most sporting
activities. Over time, gold will typically show evidence of wear and a natural
patina will occur on the surface. Even with the durability of an "A" ring,
you should avoid contact with hard metal surfaces or stone. Pummeling on the
surface or serious abrasion can occur with metal or stone or rock contact. |
 |
B
Construction & Durability
Practical
Gem partially encircled with gold or
platinum protecting majority of perimeter.
Example: A well-made half-bezel, a fishtail
mounting, some channel work, and certain handmade settings in which a
substantial portion of the perimeter of the gem is protected. This category
may also include some contemporary mountings in which the gem is recessed
and a portion or portions of the gem are exposed. Certain types of bar-set
work and medium weight bezel designs may be included in this category.
Expectations & Limitations
Rings with gems locked in place with half, or more than half their
perimeter secured can be very strong. Exposed edges of gems, and the girdle
(the perimeter) are at risk of abrasion or chipping. Although this
half-bezel technique lightens the design and gives a lighter, more airy,
appearance, a higher degree of caution should be exercised when wearing one
of these rings than when wearing an "A"ring. |
 |
C
Construction
& Durability
Good
Gem held in place by either 14K white gold,
18K white gold, or properly
constructed platinum head structure. This may be a 6-prong head or a 4-prong
head. (Note: Typically 6-prongs are safer because if anything should happen
to one prong, the five remaining prongs will usually still hold a gem in
place. On 4-prong heads, if the prongs are made sufficiently heavy, the
extra weight can compensate and provide as many years of wear as a 6-prong
head.) (Most gems, however, which are lost are lost out of 4-prong settings.
This risk can be reduced by periodic safety checks.) Medium weight bar-set
work may be included in this category. Occasionally heavy yellow gold prongs
may be rated in this "C" category.
Expectations & Limitations
Prong-set rings can best be described as relatively thin spindly little
shafts of gold or platinum. Usually six or four rising from a central point
with a gem resting on a beveled shelf near the top with the tips bent to
cinch the gem in place. All prong setting is at risk of inadvertent bumping
of a prong which can cause a gem to loosen or come out of its setting. White
gold, 6-prongs or heavier construction of prongs can increase the durability
of a prong-set ring, but there is a wide range of activities during which
all prong-set rings should be removed. |
 |
D
Construction
& Durability
Fair
Gem held in medium to lightweight yellow
gold prong work. Also very small gems require proportionately smaller
prongs. Even though gems may be set in white gold or platinum, the tiny size
of the prongs leave gems vulnerable to both catching and wear.
Expectations & Limitations
This type of jewelry can best be described as limited to dress-up occasions
or very careful wear during moderate activity. |
 |
E
Construction
& Durability
Poor
Gems set in very light prong, bezel, or bar
work. Typically a minimal amount of gold has been used. Due to the nature of
the very light construction, these types of rings and jewelry are the most
delicate.
Note where the arrow is pointing above:
although the prong appears heavy, it is thin. There is very little going
over the edge of the gem to hold it in place.
Expectations & Limitations
This is often problematic jewelry at high risk for damage. Solutions are
often limited to resetting gems into a new mounting. Repairs to one part of
a ring may only accelerate wear to another portion of the ring or aggravate
an underlying condition. |
| |
F
Construction
& Durability
Do Not Buy
Gems set in ultra-thin prong work. Examples
are rings with paper-thin prongs or only two prongs holding one gem. Often
found in jewelry of foreign construction, mass produced television bargain
jewelry, or discount house promotional jewelry.
Expectations & Limitations
Avoid buying jewelry in foreign countries. If it is a recent domestic
purchase, check to see if they allow returns and attempt to receive a
refund. Some designs, although visually attractive and very low priced, have
so little holding gems in place there are no practical ways to repair,
restore, or even make minor modifications.
