Tanzanite

Tanzanite is a natural gemstone renowned for its intense blue-violet colour and exceptional beauty. Composed of zoisite (Ca2Al3(SiO4)(Si2O7)O(OH)), it has a moderate hardness (6.5 to 7 on the Mohs scale), which gives it good resistance to wear when carefully set. Prized for its shimmering reflections and crystalline clarity, tanzanite shows shades ranging from deep blue to delicate violet, sometimes with faintly purple tones. Its rarity — it comes exclusively from deposits in Tanzania — makes it a highly sought-after and precious stone in fine jewellery. Elegant and refined, tanzanite enhances every creation, modern or classic.
