by deorwine » Jan 8, 2019 Oh! Exactly the same thing happened to me, with the stone in my avatar, which I had been wearing a lot in a ring. I had my jeweler reset it. When I got the new ring back, I said, "Wow, I can't believe this is the same stone!" -- it went from a sleepy stone to a much more crisp sparkly one, and if I remember correctly I did perceive more purple in it in fluorescent/incandescent light (though not in daylight). I mean, I was mostly joking -- it was clearly the same stone, with a wonky native cut. And the picture in my avatar is from the original vendor and you can see it always had some purple in it. Turns out all they did was clean it really well before putting it in the new setting! On my finger it had gotten dirty (I'd been cleaning it but I guess wasn't able to clean it as well as they did), which made it more sleepy-looking. I would also not be surprised if something about the grime changes the way the light goes through the stone, potentially changing the perceived color somewhat. OK, now I want someone to do an exhaustive color comparison with dirty and clean stones!
