One thing every kunzite buyer should know before anything else: the pink in this gem is sometimes boosted. Kunzite is commonly irradiated or heated in the trade to strengthen its colour, and that colour can later fade after years in strong sunlight. Neither is a defect, but both are worth asking about and should be disclosed.

So here is what we can say about this 3.70 carat stone. Its body colour is a soft champagne with only a whisper of pink, not the saturated rose most people imagine. It rates 6.5 to 7 on the Mohs scale, with perfect cleavage, so protect it from sharp knocks and keep it away from steam and ultrasonic cleaners.

Paler kunzite usually costs less per carat than deeply pink material, and a stone like this can look lovely beside yellow gold.

Quote reference GSN-KZ-02 when you message us about it. The photographs show this exact stone, so what arrives at your door is the piece you chose on screen.

Between two and six carats is the range most people choose for a gents' ring or a noticeable pendant. Here colour drives the price more than size does, which is why two stones of near-identical weight can be priced very differently.

On the Mohs scale kunzite rates 6.5 to 7. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy kunzite from, make sure of three things: the stone is natural rather than lab-grown, glass or glass-filled; any treatment is stated in writing; and the weight quoted is the weight of the finished stone. We check every kunzite for those three points before it is listed, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
