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 set into a wraptight or cinchmount setting, hanging from a 14k Gold Leverback Earring.    By the way, did you notice these are  6mm round stones.  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.
