Sunset in Arizona, Autumn in North Carolina? Sort of an iridescent Orange/Pink/Yellow/Whatever.... It catches light like crazy -- I mean, bright sunlight makes it go berserk, and even in a low-lit restaurant, it can't hide. It insists on being seen, and does SUCH a marvelous job of it. Cool stone, however you describe it. Very pretty. A comfortable 6 carats, this is a really nice stone, clean and clear, with tons of bright, sparkly iridescent fire. Gives me goosebumps just to look at it., but then, I like Twilight Fire set in Sterling Silver. This ring is a nice simple design. It's more about the stone than the ring, but it's a nice setting just the same. At SylvaRocks, all of our Sterling Silver is made with a state of the art alloy which modifies the traditional Sterling Silver alloy (92.5% silver + 7.5% copper) by replacing some of the copper with the metalloid Germanium. Adding Germanium to the Sterling Silver results in a highly tarnish resistant silver. Since the resulting metal is still 92.5% pure silver, is still qualifies as Sterling Silver -- just better. (for more information, Google the term Argentium Sterling Silver) _________________________________________________________________________ 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.
