When this lovely necklace was made they laced the Green beads with Aventurine which makes the gold roping in the green beads. They are the most beautiful beads. Then there is even size navy blue bead, that show off the green. There are little gold spacer between all. This is a hand crafted necklace. The beads are all strung on strong chain. There is an inch gap that will hang in the back to give the beads a chance to hang right. The closure is a safety clasp. The length of the necklace is 23 inches and the green beads are 1/2 inch wide and 3/4 long. the navy beads are 3/8 inch. A lovely and impressive necklace in perfect shape. Aventurine from Kansas. !
