This is a new color for Topaz.  It may be the best color yet.  It reminds you a lot of of very high grade Aquamarine, and yet lighter Apatite comes to mind as well.  The stone clarity is amazing , the faceting is near perfect - -the result is a stone that just POPS at you.  That's the best I can describe it.  Color, cut and clarity all combine to produce one of the prettiest combinations we've ever seen.

They are set into a wraptight or cinchmount setting, hanging from 14k Threaders!
Essentially a variation on the bezel setting, it allows the most show of stone for the least expense in gold. It's a good stable setting that doesn't set you back a month just to get one.
