This is a top grade strand of bright royal purple “gel” sugilite beads complemented by solid 18k gold beads and clasp. It has a custom cut and perfectly matched 16.0 ct sugilite focal bead at the center.
Sugilite is a relatively new gemstone that is found only in South Africa and is no longer commercially available. The rondelle beads in this strand range from approx. 8 mm down to 4.0 mm except for the center bead which is 20.0 mm long and 12mm wide at the widest point. Wire protectors, and crimps, which are subject to wear/stress, are made with gold filled components for greater durability.
Beware of fake sugilite and simulants for sale on the Internet. I have seen dyed chalcedony and jasper marketed as sugilite. You can be confident that you get what you paid for at ARJ.
