This necklace features dark blue opal in a faceted disc shape with 18K yellow gold beads.
The gemstones are considered black, but they are a deep blue and the flash is incredible. They're graduated in size from 3.5mm to 7mm and accented with 18K gold beads at the side. Finished with 14K lobster claw and 2" of 14K gold chain for adjustment from 18" to 20" in length.
Both lengths are shown in the photos above.
