Frequently Asked Questions
What makes Tanzanite so rare and valuable?
Tanzanite is found in a single, remarkably small mining area near Mount Kilimanjaro in Tanzania — a deposit estimated to be over a thousand times rarer than diamond. Its extraordinary trichroism, which produces shifting tones of blue, violet, and burgundy depending on the angle and light source, makes each stone a genuinely unique optical experience. This combination of geographic exclusivity and visual complexity places Tanzanite among the world’s most sought-after collector gemstones.
Has this Tanzanite been treated, and is that standard practice?
Yes, this 1.38-carat Tanzanite has been heat-treated — a process that is considered completely standard and universally accepted within the gemstone industry. In its natural state, Tanzanite often presents with brownish or reddish undertones; gentle heating stabilises the crystal structure and brings forward the signature blue-violet hues that the stone is celebrated for. The treatment is permanent, does not affect the stone’s durability, and is fully disclosed as part of Yala Gems’ commitment to transparency.
Is this Tanzanite suitable for everyday jewellery such as a ring?
Tanzanite registers at 6 to 7 on the Mohs hardness scale, which means it is best appreciated in jewellery settings that offer it a degree of protection — such as bezel-set rings, pendants, earrings, or bracelets worn with care. For those who wish to wear Tanzanite daily in a ring, a protective setting style and mindful habits are recommended. Its vivid colour and transparent clarity make it an exceptional choice for statement pendants and earrings where it can be admired freely and safely.
What metal settings complement the purplish-blue colour of this Tanzanite?
The cool, violet-inflected blue of this 1.38-carat Tanzanite pairs magnificently with white gold or platinum, which amplify the stone’s icy depth and allow its natural colour to remain the focal point. Yellow gold creates a warmer, more antique-inspired contrast that can draw out the gemstone’s violet and burgundy undertones beautifully. Rose gold offers a romantic, contemporary pairing that softens the stone’s cooler tones with a blush warmth. Our team at Yala Gems is happy to advise on custom setting options to suit your vision.
