Whether you’re celebrating a June birthday, honoring
Florida’s state gemstone or tapping into this

Like diamonds and other gemstones, moonstones are
assessed by the
4Cs: color, clarity, cut, and carat weight. An
American Gem Society jeweler can help you find the
moonstone you want.
Generally, the more transparent the stone and the
bluer its adularescence (or sheen), the higher its
value. Historically, the highest-quality moonstone gems came from Sri Lanka, but since those sources have
essentially dried up, prices of classical blue
moonstone have risen sharply.
Indian moonstones, in colors ranging from brown to
orange and green, are more readily available and
affordably priced. This means everyone can find a
moonstone gemstone to fit their style and budget.
Classical moonstones are cut as cabochons with a
high dome to accentuate the adularescence. Large
blue moonstones (over 15 carats) are rare, but
stones with silvery white adularescence are
available in sizes up to hundreds of carats.
This beautiful gemstone’s weakness is its relatively
low hardness of 6 on the Mohs scale, making it prone
to stress cracking. Care is required with moonstone
jewelry like rings or bracelets, so brooches and
pendants are often preferred instead.
There is no synthetic moonstone on the market.
Although it has been simulated by chalcedony and
man-made spinels, these imitations are easy to spot.
