Tanzanite Stone Necklaces – Rare, Regal & Hatton Garden Crafted

Tanzanite is one of the rarest and most extraordinary gemstones in the world — found only in a small area at the foot of Mount Kilimanjaro in Tanzania, it is estimated to be a thousand times rarer than diamond. Its extraordinary trichroic quality means it displays different colours depending on the angle from which it is viewed — deep blue, violet, and burgundy — creating a gemstone of unparalleled depth and complexity. A tanzanite necklace is not simply a piece of jewellery; it is a piece of the natural world that is genuinely irreplaceable.

At FineDiam, our tanzanite necklace collection celebrates this extraordinary gemstone, pairing its natural brilliance with carefully selected diamond accents, all handcrafted in our Hatton Garden, London workshop by expert jewellers. Every piece is UK hallmarked by the London Assay Office and arrives in a luxury FineDiam gift box, beautifully presented and ready to wear. Explore our full range of gemstone jewellery to find a perfectly matched set.

Why Tanzanite?

Discovered in 1967 by Maasai tribesmen in the Merelani Hills of northern Tanzania, tanzanite was introduced to the world by Tiffany & Co., who named it after its country of origin. Its extraordinary blue-violet colour — which shifts between deep sapphire blue and rich violet depending on the light — quickly made it one of the most coveted gemstones in fine jewellery. Tanzanite is the December birthstone, making a tanzanite necklace one of the most personal and meaningful gifts you can give to someone born in that month.

The most prized tanzanites display a vivid, saturated blue-violet with strong colour saturation and minimal inclusions. Our Hatton Garden jewellers select every tanzanite in our collection for its colour depth, clarity, and brilliance, ensuring that each piece meets the highest standards of quality.

Our Tanzanite Necklace Styles

Tanzanite Solitaire Pendants

A tanzanite solitaire pendant places a single, carefully selected tanzanite at the centre of the design, allowing the stone’s extraordinary colour to speak for itself. Our solitaire pendants are available in oval, cushion, and pear-cut tanzanite, set in four-prong or bezel settings in white gold, yellow gold, and platinum. A tanzanite solitaire pendant is the purest expression of this extraordinary gemstone — elegant, understated, and genuinely individual.

Tanzanite & Diamond Halo Necklaces

A tanzanite centre stone surrounded by a halo of brilliant-cut diamonds — one of the most striking combinations in gemstone jewellery. The diamond halo amplifies the tanzanite’s natural brilliance while adding the sparkle and structure that elevates the design from beautiful to extraordinary. Available in white gold and platinum.

Tanzanite Drop Pendants

Our tanzanite drop pendants allow the stone’s extraordinary colour to catch the light with every movement, creating a necklace with elegance and drama in equal measure. These designs range from simple single-stone drops to more elaborate designs featuring diamond accents, and they make a stunning choice for special occasions, anniversaries, and milestone gifts.

Tanzanite & Diamond Necklaces

Tanzanite and diamonds are a natural pairing in fine jewellery — the deep blue-violet of the tanzanite and the brilliant sparkle of white diamonds create a combination that is both striking and refined. Our tanzanite and diamond necklaces are available in a range of styles and settings, with both natural and lab-grown diamond options available, all IGI and GIA certified.

Tanzanite Necklaces as a Gift

A tanzanite necklace is one of the most distinctive and memorable gifts you can give. As the December birthstone, it is a natural choice for December birthday gifts and Christmas presents. Its rarity and extraordinary colour also make it a particularly meaningful choice for milestone anniversaries and special occasions — a gift that communicates genuine thought, care, and appreciation.

Every FineDiam tanzanite necklace arrives in luxury gift-ready packaging with free UK delivery, beautifully presented and ready to give. Explore our full range of tanzanite bracelets to find a perfectly matched set.
