sapphire - alternative birthstones

Sapphire comes in many different colors, not just classic blue, as this set of 17 oval-cut sapphires demonstrates. It’s not just the September birthstone, either. If you’re a Taurus or named Paul, or if you were born in the 10 AM hour or on Thursday, you could make sapphire one of your alternative birthstones. 7.78 ctw, Sri Lanka and Myanmar. © Rob Lavinsky, www.iRocks.com.

Choose stones associated with zodiacal signs or months symbolic of angels. You can even forgo your birth month and pick a gem associated with the day of the week or hour of your birth.

In the 19th century, the term chrysolite referred to yellow-green chrysoberyl as well as peridot and prehnite gems. However, that name is no longer used. (Chrysoberyl, peridot, and prehnite are all distinct gem species).


This peridot, cut from a pallasite meteorite found in Indonesia, features some needle-like inclusions — crystals trapped within the gem — that have an iridescent flash. Portuguese oval-cut, 0.29 cts, 4.7 x 3.6 mm. © The Gem Trader. Used with permission.
