Tanzanite: the Ultimate Jewellery Guide

Tanzanite is one of the most extraordinary gemstones in the world — admired for its deep violet-blue hues and its incredible rarity. Discovered only in the 20th century and found in just one location on Earth, this gemstone has quickly become a modern treasure, adored for its exotic beauty and luminous charm.

As the birthstone for December, tanzanite is both meaningful and luxurious, making it a perfect choice for statement jewellery and milestone gifts.

History & Symbolism of Tanzanite

Tanzanite was first discovered in the 1960s in northern Tanzania, near Mount Kilimanjaro — the only place in the world where it is found. Believed to be 1,000 times rarer than diamonds, its exclusivity has made it one of the most coveted modern gemstones.

Symbolically, tanzanite is linked with transformation, calm, and spiritual awakening. Its shifting colours, which change between blue, violet, and burgundy depending on the light, embody creativity, individuality, and inner strength.

Colour Range & Beauty

Tanzanite is renowned for its unique pleochroism — the ability to display different colours when viewed from different angles. Its shades include:

  • Violet-Blue: The most recognisable and popular hue.

  • Deep Indigo: Rich and luxurious, often the most valuable.

  • Soft Lavender-Blue: Lighter tones, delicate and dreamy.

The most prized tanzanites show a vivid, saturated blue-violet, often compared to sapphire but with a softer, more romantic glow.

Popular Tanzanite Jewellery Styles

Tanzanite’s exotic appeal makes it a favourite for statement and bespoke designs. Popular styles include:

  • Tanzanite Solitaire Rings – Bold, luxurious centrepieces.

  • Tanzanite & Diamond Earrings – A radiant combination of colour and sparkle.

  • Three-Stone Tanzanite Rings – Symbolising past, present, and future.

  • Tanzanite Pendants – Perfect for December birthdays or anniversary gifts.

  • Art Deco & Modern Cocktail Rings – Showcasing the gem’s vibrant tones.

Choosing a Quality Tanzanite

When selecting tanzanite, consider the following:

  • Colour: Rich, saturated blue-violet tones are the most valuable. Paler stones are more affordable but still beautiful.

  • Clarity: Most fine tanzanites are eye-clean, meaning they have no visible inclusions.

  • Cut: Cushion, oval, and emerald cuts enhance the stone’s depth of colour, while brilliant cuts maximise sparkle.

  • Carat: Larger tanzanites show more intense colour and rarity, making them especially prized.

Caring for Tanzanite Jewellery

Tanzanite has a hardness of 6.5 on the Mohs scale, making it softer than sapphires or diamonds. It requires gentle care to maintain its beauty.

Care Tips:

  • Clean gently with warm water, mild soap, and a soft brush.

  • Avoid ultrasonic and steam cleaners.

  • Store separately to prevent scratches from harder gemstones.

  • Remove before physical activity or exposure to strong chemicals.
