Ridiculous! There is a big thing made about Sleeping Beauty turquoise be rare because the mine has closed, but there is an awful lot of it about and at much cheaper prices. Not keen on it myself, I like the darker colours with some texture.
Now I have SB turquoise but that's more because I fell in love with a really pretty pair of earrings. They're a bit like a wee bunch of danglies with a mix of silver discs and bezel set turquoise on different lengths of silver chain. Then I got a matching pendant and ended up with a ring and a bracelet.
Not sure I'd really have collected SB if I hadn't started with the earrings.
Have a lovely turquoise station necklace. It's really not good quality, lots of inclusions and barely better than pebbles on a beach but I love it. Was cheap as chips ... from TJC I think. It's on a silver chain though and with a summer top or frock it's really quite pretty. Hardly a heirloom piece but that's the fun of jewellery I think.
