Moonstone

Moonstone, the alternate birthstone for the month of June, is considered a sacred stone in India. The translucent gem that is found in rainbow of colors has a beautiful, silvery iridescence that is known as adularescence, a quality of a particular type of feldspar. Moonstones are mined in Sri Lanka, Southern India and Brazil. They are generally reasonably priced gemstones, though some of the rarer varieties can command high prices.

Moonstone buying guide

The 'ideal' moonstone is colorless, with a blue sheen and near perfect clarity. The surface reflects an iridescence that is almost the exact opposite of that found in an opal. Size, color, cut and clarity are the main determining factors of pricing for moonstones.

Caring for moonstones

All the basics of gem care apply to moonstones. They are relatively soft stones, and should be protected from chipping and cracking, extreme temperature changes and household chemicals.

Everyday caution

Housework and moonstones don't mix. Take off your moonstone jewelry before engaging in any activity that has a high chance of banging the stone against hard objects, or before doing household cleaning. Avoid contact with makeup, hairspray and other cosmetics. Abrasive cleaners can scratch the surface of the stone, dulling its iridescence.

Cleaning moonstone jewelry

Since much moonstone jewelry is antique, be sure to check settings carefully for looseness or wear. Moonstone jewelry can be cleaned using a mild commercial cleaner, or your own solution of warm water and dishwashing liquid. Allow the piece to soak for about 15 minutes in cleaning solution, then carefully clean with a soft brush, paying particular attention to the areas around setting prongs and the under the stone. Dry well with a soft cloth before storing or wearing.

Storing moonstone jewelry

It's important to protect moonstone from being scratched by other harder gems. Store moonstone jewelry in separate compartments or pouches inside a jewelry box.
