The are large green turquoise beads with silver end caps.
These amazing Thai beads have come a long way to our shop. Our amazing finder Michael found them in Thailand and brought them over for us. When they are gone, they are gone. We may never get any more of them! They are made of green turquoise and since they are handmade, no 2 look exactly alike.
