Frequently Asked Questions
What makes tanzanite so rare compared to other coloured gemstones?
Tanzanite is found in only one place on earth — a small mining corridor near Mount Kilimanjaro in Tanzania. Geologists estimate the conditions that created it will never be replicated, making the existing supply finite by nature. This geological exclusivity places tanzanite among the most collectible gemstones in the world, coveted by connoisseurs and jewellery houses alike.
What does “heated” treatment mean for this tanzanite?
Heat treatment is the standard and universally accepted practice for tanzanite. In its natural state, tanzanite often presents with a brownish or muted tone. Gentle controlled heating enhances the stone’s inherent blue and violet hues, revealing the vivid purplish-blue colour tanzanite is celebrated for. This treatment is permanent and does not diminish the stone’s value or integrity.
Is this tanzanite suitable for everyday jewellery such as a ring?
Tanzanite carries a Mohs hardness of 6.5 to 7, which makes it well-suited for pendants, earrings, and bracelets. For rings intended for daily wear, a protective setting style — such as a bezel or halo — is advisable to safeguard the stone from impact. With thoughtful craftsmanship and mindful care, this tanzanite will reward its wearer with lasting beauty for generations.
What metal settings complement the purplish-blue colour of this tanzanite?
The cool, velvety purplish-blue of this tanzanite pairs exceptionally well with white gold or platinum, which allow the stone’s colour to speak without interference. Yellow gold offers a warmer, more contrasting aesthetic that can beautifully intensify the violet undertones. Rose gold creates a romantic, contemporary pairing that is increasingly favoured in bespoke jewellery design. Our team at Yala Gems is happy to advise on a custom setting that honours this stone’s character.
