These earrings display spectacular London Blue Topaz.  They are clean, with no cracks or inclusions.  The color is incredible -- so deep, you'll want to go swimming in it.

These stones 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.
