Question 1

What is tanzanite?

Accepted Answer

Tanzanite is a rare blue-to-violet gemstone found only in one location on Earth—near Mount Kilimanjaro in Tanzania. It’s a variety of the mineral zoisite and is prized for its unique colour and exclusivity.

Question 2

Is tanzanite more rare than diamonds?

Accepted Answer

Yes. Tanzanite is significantly rarer than diamond because it comes from a single, limited source. Some experts believe the supply could be depleted within decades.

Question 3

What colour tanzanite is most valuable?

Accepted Answer

The most valuable tanzanite displays a deep, vivid blue with flashes of violet. Strong colour saturation and minimal inclusions increase value.

Question 4

Is tanzanite a good investment?

Accepted Answer

Tanzanite can be a strong long-term investment due to its rarity and single-source origin. High-quality stones with deep colour and good clarity tend to hold and increase value over time.

Question 5

Can tanzanite be worn every day?

Accepted Answer

Tanzanite is softer than many gemstones (6–7 on the Mohs scale), so it’s best suited for occasional wear or protected settings like pendants and earrings rather than everyday rings.

Question 6

Does tanzanite change colour?

Tanzanite is known for its pleochroism, meaning it can show different colours (blue, violet, and burgundy) when viewed from different angles.

How do you care for tanzanite jewellery?

Accepted Answer

Avoid ultrasonic cleaners and harsh chemicals. Clean gently with warm soapy water and store separately to prevent scratches.
