October Birthstone — Australian Opal

Opal is the birthstone of October and Australia’s national gemstone — and the traditional stone of the 14th wedding anniversary. Every piece here holds natural Australian opal, one of one, because no two opals carry the same fire.

For an October birthday, the gift is genuinely unrepeatable: solid Australian opal in gold or gold-plated sterling silver, made in Australia.
