About Our Tanzanite Collection
Tanzanite is a blue-violet variety of the mineral zoisite, prized for its strong pleochroism — the way it can show different colours, including blue, violet, and burgundy, depending on the angle it's viewed from. It rates 6–6.5 on the Mohs scale, softer than sapphire or ruby, so tanzanite pieces suit earrings and pendants especially well, while rings benefit from protective settings and a bit more careful daily wear.
Every tanzanite in this collection is a natural, hand-selected stone, available in 925 sterling silver or 9KT–18KT gold. Gold settings are BIS hallmarked, and every purchase is backed by our lifetime warranty and buyback programme. Need to return or exchange an order? See our Returns & Exchange Policy for full details.
Tanzanite is a recognised December birthstone, alongside turquoise and zircon, and a popular choice for its rare, distinctive colour.
Caring for tanzanite: avoid ultrasonic cleaners, harsh chemicals, and sudden temperature changes. Clean gently with mild soap, lukewarm water, and a soft cloth, and store pieces separately from harder gems. See our full jewellery care guide for more tips.
Frequently Asked Questions
What is natural tanzanite jewellery?
Natural tanzanite jewellery features genuine tanzanite gemstones — a blue-violet variety of zoisite known for its distinctive colour and rarity.
Why does tanzanite show different colours from different angles?
Tanzanite is strongly pleochroic, meaning it can display different colours — blue, violet, and burgundy — depending on the angle from which it's viewed and how it's cut.
Is tanzanite durable enough for daily wear?
Tanzanite rates 6–6.5 on the Mohs scale, softer than sapphire or ruby, so while it's suitable for regular wear, rings benefit from a protective setting and a bit more care than harder gemstones.
Is tanzanite a birthstone?
Yes. Tanzanite is a recognised birthstone for December, alongside turquoise and zircon.
Is tanzanite usually treated?
Nearly all tanzanite on the market is heat-treated to develop its signature blue-violet colour. This is standard, widely accepted practice in the trade, not a defect.
How should I care for tanzanite jewellery?
Clean gently with mild soap, lukewarm water, and a soft cloth. Avoid ultrasonic cleaners, harsh chemicals, and extreme temperature changes, and store pieces separately in a soft pouch or lined jewellery box.
