A taste of the stone

December Birthstone Jewellery

Nº 12·Turquoise & Tanzanite·Sagittarius · Capricorn

December runs sky-blue to blue-violet: turquoise — much of it stabilised, which honest sellers state — and tanzanite, the one-hill stone from Tanzania, mostly in delicate violet-blues. Two different buys with the same December address.

FAQ

Buying December's birthstone

What makes a good December birthstone gift?▾

A turquoise & tanzanite piece is the natural December birthday gift. Pendants and stud earrings are the safest choices — no ring-size guesswork — while a ring or bracelet makes a bigger statement. Every piece here is labelled for exactly what it is (the metal, and whether the stone is natural, lab-created or simulated), so you can match the gift to your budget honestly.

Are lab-created or simulated stones worth buying?▾

Often, yes. A lab-created stone is the same material as a natural one at a fraction of the price; a simulated stone (or CZ / moissanite) only imitates the look. Neither is "fake" when it's sold honestly — so every piece on this shelf is labelled natural, cultured, lab-created, or simulated, and none is passed off as another.

What should you look for when buying December's birthstones?▾

Turquoise — look for sky blue, and note it's softer (Mohs 5–6), so it suits a pendant or earrings better than an everyday ring. Tanzanite — look for blue-violet, and note it's softer (Mohs 6–7), so it suits a pendant or earrings better than an everyday ring. Above all, check what the piece actually is — solid gold versus plated, natural versus lab-created — which every listing here states plainly.
