MC Crystal Beads
Suncuts (or bicones) are just one specific cut of so called Machine-Cut Beads or otherwise known as tin cut beads. The production technology, type of glass (crystal) used and their properties are the same as imitation MC stones. They ideally combine the brilliance and optical qualities of crystals with multiple use of beads.
The name suncut is used for many years by the local cutters since when looking from the side this particular cut evokes the beams from the sun.
