Sunstone is sold by the carat at a fraction of the price of most gems, and this 5.8 carat piece is a clear example: Rs. 1,310 in total, about Rs. 226 per carat. The per-carat figure makes it an easy stone to try if you have not bought a loose gem before.

Sunstone is known in the trade for a glittery, sparkling effect that comes from tiny reflective inclusions, and buyers usually choose it for that play of light. Look at it in sunshine and under a lamp to see how it behaves when you receive it. Its Mohs hardness is 6 to 6.5, so it is softer than topaz or sapphire and suits a pendant or an occasional ring better than a ring worn every day.

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 sunstone rates 6 to 6.5. 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.
