GEMSTONES CARE

Some gemstones require special care, but certain
basic precautions apply to all jewelry set with
gemstones. Avoid excessive impact against hard
surfaces, extreme temperature changes and contact
with perfumes, cosmetics and household chemicals.
Prong settings are particularly vulnerable and
should be examined regularly to be sure they hold
the stone securely. Jewelry set with gemstones
can be maintained with a nonabrasive jewelry
cleaner. Ultrasonic cleaning is not safe for
many gemstones, so we advise against this method.
To clean diamonds, use a mild solution of 6 parts
water to 1 part ammonia and apply with a very soft
bristle brush.
