Birthstone
Opal is the official birthstone for October, alongside tourmaline, and is also the gem of the 14th wedding anniversary. Its name comes from the Sanskrit “Upala,” meaning “precious stone,” and the Greek “opallios,” meaning “to see a change of colors.” This unique gem belongs to the silica group and is made up of microscopic spheres that diffract light, creating the beloved play-of-color. Long associated with luck and inspiration, opals remain one of nature’s most enchanting treasures.
