gemstones usually go safely into ultrasonic cleaners. A home ultrasonic cleaner should be used with extreme
caution. It can be used to clean lightly included
Ruby, sapphire, diamond, iolite, amethyst, citrine,
garnets, chrysoberyl, and unadorned jewelry
but it may damage gems like emerald, pink tourmaline,
peridot, 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.
Soaking a Ruby in vodka overnight will loosen
stubborn dirt, which can then be rinsed and brushed
away. Always use a soft brush but no abrasives, not
even toothpaste. Abrasives such as this will not damage a Ruby,
but will scratch the softer silver, gold or platinum
To protect the beauty of your gems and jewelry, make
sure you store each piece separately: Gems may not only scratch
each other but also the metal components of the jewelry. Avoid creating
a tangle of jewelry by wrapping each piece individually,
or keeping it in its own compartment. This is especially important 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.
