If you like Smoky Quartz, you're gonna love these.  I hand pick every Smoky Quartz I set, and I'm very picky.  I don't like them really dark, 'cause light can't get in there and bounce back at you.  I CAN set very light ones if that's what you prefer, but if left up to me, the stones are medium, and selected for good cut.

These stones are 6mm rounds set into a wraptight or cinchmount setting, hanging from a 14k Gold Leverback Earring.   

Essentially a variation on the bezel setting, it allows the most show of stone for the least expense in gold.

A good stable setting that doesn't set you back a month just to get one.
