Stone Type _________________ Swiss Blue Topaz Approximate Stone Size _______ 8x6mm Approximate Stone Weight _____ 3 ct Jewelry Metal _______________ Solid .925 Sterling Silver Our Warranty _______________ A full year on workmanship Our Guarantee _____________ Totally unconditional 30 day guarantee ______________________________________________________________________ Swiss Blue Topaz -- what you get when you expose an ordinary clear topaz to radiation 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 sky straight up overhead on a clear, bright day. Just the most awesome blue you ever saw. I'm just totally in love with them. These stones are set into a sturdy 4 prong basket. We cast our own mountings and will never use flimsy "snap tight" stuff... It allows the most show of stone for the least expense in silver. It's a good stable setting that doesn't set you back a month just to get one. ______________________________________________________________________ BTW, Since we make this from scratch after you order it, we have a lot of flexibility. We can also make this for you in either 14k yellow gold or 14k white gold. 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.
