Frequently Asked Questions
What makes Tanzanite such a rare and coveted gemstone?
Tanzanite is found in only one place in the world — a narrow strip of land near Mount Kilimanjaro in Tanzania — making it geologically unique and inherently finite. Its remarkable trichroism, the ability to display blue, violet, and burgundy tones depending on the angle of light, gives each stone a living, shifting character that no other gemstone quite replicates. This combination of extreme rarity and visual complexity is precisely why Tanzanite has become one of the most sought-after gemstones in fine jewellery since its discovery in the late 1960s.
Is a 1.40-carat oval Tanzanite suitable for everyday jewellery wear?
With a Mohs hardness of 6 to 7, Tanzanite is a durable gemstone but does benefit from thoughtful care. It is a wonderful choice for pendants, earrings, and bracelets, which experience less direct impact in daily wear. For rings, a protective setting — such as a bezel or halo design in white gold, yellow gold, or platinum — is recommended to preserve the integrity of the stone over time. With the right setting and mindful handling, this 1.40-carat oval can be enjoyed as an everyday luxury.
What metal settings best complement the blue colour of this Tanzanite?
The vivid blue of this 1.40-carat oval Tanzanite pairs beautifully with a range of precious metals. White gold and platinum create a cool, contemporary contrast that allows the blue tones to appear crisp and luminous. Yellow gold, on the other hand, adds warmth and an Art Deco sensibility, gently drawing out any violet undertones within the stone. Rose gold offers a romantic, modern aesthetic that softens the gem’s intensity. Ultimately, the choice of metal is a matter of personal style — each brings a distinctly different character to the finished piece.
How should I care for and clean my Tanzanite gemstone?
Tanzanite is best cared for with gentle cleaning using warm water, a mild soap, and a soft brush — avoiding ultrasonic or steam cleaners, which can stress the stone. It is advisable to remove Tanzanite jewellery before engaging in physical activity, household chores, or exposure to harsh chemicals. When storing, keep your Tanzanite separately from harder gemstones such as diamonds or sapphires to prevent surface abrasion. With attentive care, this gemstone will retain its extraordinary colour and brilliance for generations.
