Stone Type _________________ Smoky Quartz Approximate Stone Size _______ 10x8mm Approximate Stone Weight _____ 3.3 ct Jewelry Metal _______________ Solid .925 Sterling Silver Our Warranty _______________ A full year on workmanship Our Guarantee _____________ Totally unconditional 30 day guarantee ______________________________________________________________________ When I first saw these Smoky Quartz, cut using the Quantum, or concave Cut -- I fell in love... This cut is so fluid, the sparkle so intense. I mean really, Smoky Quartz was always sort of a dull brown. NOT ANY MORE. These are really cool stones, with a life you've never seen before. Very pretty. This stone is 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.
