Frequently Asked Questions
What makes tanzanite so rare and sought after?
Tanzanite is found in only one location in the world, making its supply inherently finite and its desirability enduring. What further distinguishes it is its extraordinary trichroism — the ability to display blue, violet, and burgundy tones depending on the viewing angle and light source. This 0.98-carat specimen, with its rich purplish-blue transparency, exemplifies the colour saturation that collectors and jewellery designers prize most highly.
Is the heat treatment on this tanzanite considered acceptable in the trade?
Absolutely. Heat treatment is the universally accepted and standard practice for tanzanite, used to stabilise and enhance the stone’s characteristic blue-violet hue from its naturally more brownish rough state. This process is permanent, does not affect the stone’s durability, and is fully disclosed as an industry norm. The treated status of this tanzanite in no way diminishes its value or beauty — it is, in fact, how virtually all gem-quality tanzanite on the market is presented.
What jewellery settings would complement this 8 x 6 mm oval tanzanite?
The oval mixed cut at 8 x 6 mm is a beautifully versatile dimension, lending itself to a wide range of bespoke designs. The stone’s purplish-blue character is especially luminous when set in white gold or platinum, which allow its cool tones to radiate without competition. It would make an exquisite centre stone for a solitaire or halo ring, a refined pendant, or an elegant pair of earrings when sourced alongside a matched companion. At Yala Gems, our team is happy to assist you in envisioning the perfect setting for this stone.
How should I care for a tanzanite gemstone?
Tanzanite, while a captivating gemstone, benefits from mindful care due to its sensitivity to sharp temperature changes and hard impacts. It is best cleaned gently with warm soapy water and a soft brush, avoiding ultrasonic or steam cleaners. When not worn, store your tanzanite jewellery separately from harder stones to prevent surface scratching. For pieces intended for everyday wear, a protective bezel or halo setting is advisable to safeguard the stone’s edges and preserve its brilliance for generations.
