Chunky, genuine amethyst crystal drawer pulls / cabinet knobs bring a sophisticated, upscale look to your furniture, kitchen or bath. Each Amethyst Crystal knob is made from a chunky, lavender purple piece of genuine amethyst. The crystal is 1 1/4" to 1 3/4" long and each piece is unique. The crystal is then permanently affixed to cabinet hardware. The hardware piece has a satin nickel finish, projects 5/8" from the mounting surface before addition of the amethyst, and includes a standard 8-32 threaded 1" screw. It has a tiny nib on the bottom that keeps the knob from twisting with use, it's not visible when the knob is installed.
