The two large Turquoise nuggets in the necklace are almost 1" large. The Turquoise sphere is about 3/4" large. I have designed the center with the sphere and two antique Tibetan coins, I found in India. I have combined pyrites, fool's gold, to enhance the antique look along with Tibetan silver beads, agates, chalcedony and chrysacola beads. It wears dainty despite the length. The clasp is Tibetan Silver.
