I had a choker-style necklace made at a power stone shop, with a stone selected as the center piece. The center stone was one I chose from the display case, and I only remember that it was expensive... The name of the stone... Black Onyx? No, that's not it... I've forgotten. The stone has red, green, and blue-green sparkles within it. I also had a bracelet made at a different shop, using the same stone. The center stone is more beautiful in the choker. The bracelet is included as a bonus. If you are concerned about the details or are looking for perfection, please refrain from purchasing.
