I ordered amethyst studs for a birthday present. I received a horrid, ugly and very cheap pair of tacky fresh water pearl studs, the kind you find at flea markets with a necklace for under $10. I am waiting on their customer service to reply. They do include a return label, and request that you insure the package for tracking and include $3.99 for a "non-defective" exchange!!!! No explanations, the invoice states amethyst studs.
