In the case of Peridot
possessing a hardness of 6.5 to 7 on the Moh’s hardness
scale, home ultrasonic cleaners should not be used.
Ultrasonic cleaners can be used to clean lightly included
sapphire, ruby, diamond, amethyst, citrine, garnets,
iolite, chrysoberyl, and unadorned jewelry
but it may damage gems like emerald, pink tourmaline,
pearls, coral, lapis lazuli, malachite, turquoise, and
any gem that has many inclusions. When in doubt, don’t
use it, and as always consult a local reputable jeweler
before attempting any cleaning yourself.
To protect the beauty of your gems and jewelry,
make sure you store each piece separately. Gems may
scratch each other or the metal in your jewelry.
Avoid creating a tangle of jewelry by wrapping each piece individually or keeping it
in its own compartment. When you travel, make sure
your jewelry pieces don’t jostle each other in one bag.
Gemstones are among the most durable of nature’s
creations. With a little care, they will be as beautiful
for generations to come as they are today.
