This is a top grade strand of bright purple “gel” sugilite beads complemented by solid 18k gold beads and clasp. It has a custom cut and perfectly matched 9.65 ct sugilite focal bead at the center (see photos with dime for size/scale). Many of the beads are translucent when backlit by the sun or strong light. The last photo in the series shows four sugilite necklaces for comparison.
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. 8.5 mm down to 4.0 mm except for the center bead which is 16.0 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.
