Tanzanite Jewelry (Nano Lab Grown)

Lab Grown Tanzanite Jewelry: Rings, Necklaces and Earrings

Tanzanite is the violet blue that did not exist in jewelry until 1967. Found in a single few square kilometres at the foot of Kilimanjaro, it went from unknown to internationally famous within a decade, and its supply has been shrinking ever since. The colour is unlike sapphire: softer, more purple, and it shifts between blue and violet as you move. Our tanzanite collection includes solitaire and halo rings, accent diamond pendants and earrings, each made to order in your chosen metal and gemstone size.

What Makes Tanzanite Special

Tanzanite is the blue violet variety of the mineral zoisite, coloured by vanadium. Its defining characteristic is strong pleochroism: the same stone shows blue, violet and burgundy depending on the direction you view it from, so the cutter decides which colour will face up. Tanzanite sits at 6 to 7 on the Mohs scale, softer than sapphire, with a direction of cleavage that makes it vulnerable to sharp impact. That is worth knowing before choosing it for a ring worn daily. Our lab grown tanzanite reproduces the same colour and pleochroism with more consistency than mined material and without the supply constraints.

Tanzanite: The December Birthstone

Tanzanite is one of the birthstones for December, alongside blue topaz and turquoise, and it was formally added to the modern birthstone list in 2002, the first addition in almost a century. It is the gemstone given for a twenty fourth wedding anniversary and is associated with Sagittarius and Capricorn. Because it is found in one place on earth, tanzanite has become a symbol of rarity and of new beginnings. For a December birthday it offers something less expected than blue topaz, with a colour that no other gemstone reproduces.

Tanzanite Rings, Necklaces and Earrings

Oval and cushion cuts dominate this collection because both retain the weight and depth of colour tanzanite needs to look its best. Round brilliants bring more sparkle to smaller stones, and pear and trillion shapes are favourites in pendants. Given the stone is softer than corundum, protective settings matter: bezels and halos of accent diamonds shield the edges while adding contrast that makes the violet read more clearly. If you want tanzanite you can wear without thinking, a pendant or a pair of studs is the more practical choice than a ring.

Metals, Sizes and Made to Order Craft

Offered in Platinum 950, 14K white gold, 14K yellow gold, 14K rose gold and 925 sterling silver. White metals are the standard choice because they keep the violet blue cool and let accent diamonds do their work. Yellow gold warms the stone and pushes it toward purple, a striking and less common look. Rose gold picks up the burgundy flashes in the pleochroism. Rings are made in your exact finger size, gemstone sizes are listed on each product page, and every piece is crafted after you order.

Caring for Your Tanzanite Jewelry

Tanzanite needs more protection than most stones we sell. Never use ultrasonic or steam cleaners, and avoid sudden temperature changes. Remove rings before sport, cleaning and any manual work, and take care not to knock the stone against hard surfaces. Clean with lukewarm water, mild soap and a soft brush, then dry with a lint free cloth. Store separately in a pouch so harder gems cannot scratch it.
