The larger stones are getting increasing difficult to obtain, and the miners are raising their prices accordingly. The price you see in this listing reflects the current market, and is only going to go higher, possibly doubling before the year is out. When these stones are gone, they are gone. I'm sorry for the rapid price increase, but I have no control. These stones have, for years now, been the best London Blue Topaz on the market, but with the mines playing out, the larger ones will vanish, but the smaller ones will still be around for awhile -- but they will be going up in price. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The stone measures 16x12 mm, and weighs in the neighborhood of a huge 13 carats. The mounting is a very pretty, heavy filigree. It's a good, solid mounting; 5 grams, and very sturdy. This ring just "feels" good, and look great! ________________________________________________________________________ BTW, Since we make this from scratch after you order it, we have a lot of flexibility. We can cast this in yellow, white or rose gold, and in any of 10k, 14k, or 18k.

We enjoy a strong repeat business, and keep it by making good jewelry you'll want to wear at prices that we both can live with.
