October Birthstone: All About Opals!

 October's birthstone is a good one...opals! My mother's birthday is in October so I grew up over her various opal pieces in her jewel box. Did you know...Opal is a hardened silica gel, usually containing 5-10% water? It is therefore noncrystalline, (unlike most other gemstones) and may eventually dry out and crack. That's why it's often recommended to keep opal in water when not in use.

 Opals come in lots of different colors like orange, blue, white, pink, black and brown. There are two kinds of opals: precious, which shows flashes of iridescence and potch which are more common and often opaque, showing no iridescence.  The iridescence of precious opals is the result of the arrangement of tiny silica spheres within the stone and how they refract light. The larger the spheres, the greater the range of colors.

Australia has been the main producer of opals since the 19th century. Other mines include Czechoslovakia, Brazil, Mexico, USA and Southern Africa. It was believed that water, fire and heat are enclosed in opals so it is a remedy for many diseases. Opal helps against heart disease, calms nerves, guards against melancholy, and restores visual acuity. Because of the fiery appearance, it is a favorite stone of magicians and alchemists and has been the source of many superstitions.

These earrings are a favorite style of mine. They are called climbers or crawlers as they climb/crawl up the ear lobes. They are very comfortable to wear as there is no post backing. Additionally they can be worn swung down on either side. I like to wear one piece mixed with other styles of studs and hoops for a mismatched asymmetrical look.

Opals can be shattered or damaged beyond repair much more easily than other popular gemstones.  Because they are easily scratchedOpals aren’t recommended for ring stones,  unless the stone is placed in a protective setting or reserved for occasional wear.
Because opals are so fragile, cracking easily when dehydrated and having a relatively low MOH's scale of hardness at 5.5, the market for simulated opals has grown dramatically. Made out of Slocum stone, a resilient man made glass or in the laboratory, they are virtually indistinguishable from genuine opals and much more durable. Similar to lapis, pearls, coral and turquoise: precious opals are also highly porous, requiring gentle jewelry cleaners like Conoisseur's.  That's why I choose to use simulated opals rather than precious for my fashion jewelry line. They don't need to be treated with the care and precision that precious opals demand.
