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 a natural December birthday gift. Pendants and stud earrings avoid ring-size guesswork, while a ring or bracelet makes a larger statement. Every selection here records the listed metal and reports the gemstone classification when the source states one; an unspecified origin remains explicitly unspecified.

Are lab-created or simulated stones worth buying?▾

Often, yes. A lab-created stone has the same material composition as its natural counterpart, while a simulated stone such as cubic zirconia or moissanite imitates a look using a different material. The distinction matters more than either category being treated as inherently inferior, which is why the selections state the recorded composition plainly.

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

Turquoise: look for sky blue; at Mohs 5–6, it needs more protection from scratches and impact. Tanzanite: look for blue-violet; at Mohs 6–7, it needs more protection from scratches and impact. Blue Zircon: look for bright blue; at Mohs 6–7.5, it needs more protection from scratches and impact. Also check the recorded metal and whether the stone is natural, cultured, lab-created, or simulated.
