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 at high noon. Just the most awesome blue you ever saw. I'm just totally in love with them. It'd better be a good, clean, solid, deep sky blue, or I won't carry 'em. Fantastic color, incredible cut, perfect clarity -- all combining to create a totally awesome stone. Very pretty. 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.
