Your products are absolutely gorgeous. Unfortunately, I would be like those irritating customers who only buy the $30, $40 items and never snag your jackpot items. For the right audience I'm sure you couldn't make them fast enough. But for people on limited budgets a $170 item is probably "too rich for their blood." It sure is for me, anyway.
As one person said, can you create just as beautiful and wonderfully hand crafted items with less expensive supplies? Or perhaps you just need to market, market, market to the RIGHT audience, as another said. The people who would willingly drop that kind of money on what you create are out there, for sure. You just need to find them.
Either way, I've definitely been drooling over your pendants. I only wish I could afford them.
