What is December's birthstone?

December's birthstone is tanzanite (with turquoise, zircon & blue topaz as alternates) — violet-blue tanzanite. We can set it into a pendant, ring, or pair of studs through build-your-own.

Is birthstone jewelry a good gift?

It's one of the most personal gifts you can give — it marks the month someone was born and is worn every day. A tanzanite pendant or studs is a timeless, meaningful choice.

Can I customize a December birthstone piece?

Yes — pick a setting and set the tanzanite (or pair it with a diamond) through build-your-own; our jewelers hand-finish it in our studio, and we can engrave a name or date.
