London Blue Topaz -- what you get when you expose an ordinary clear topaz to an electron stream at a nuclear facility. It turns into a really butt ugly color, but when you heat it up a tad, the ugly goes away and you're left with the color of the ocean off the Pacific Coast. Just the most awesome blue you ever saw, with just a hint of green to it. I'm just totally in love with them. This ring is a nice design; with a strong, heavy nugget pattern. This is a rugged design, something he's NOT going to mess up. ____________________________________________________________________ BTW, Since we make this from scratch after you order it, we have a lot of flexibility. We can also cast this in yellow, white or rose gold, and in any of 10k, 14k, or 18k. Obviously, these choices will affect the price, but email us and let us know what you're interested in, and we'll give you the best price we can live with. 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.
