Opal – one of October’s birthstones – is a phenomenal gem that shows rainbow flashes of color. There are many types of opal, with black and crystal opal being the most valuable and white and jelly opal being more commonly seen. Black opal is
treasured because its dark body color shows off its play-of-color the most vividly. As beautiful as they are, opals are more fragile than most gems and require special care. They should not be stored in dry conditions (a safe) or exposed to heat (from a heater, stove, etc.). Otherwise, they may craze (develop a series of cracks). Opals are also relatively soft and should ideally be set in a protective setting if worn as a ring stone. Learn more here https://www.gia.edu/opal
