Worn once or twice. Looks just like the JTV Jewelry pictures now selling for around $150.00 on sale. JTV description: Product Information: 5.20ctw round green chrome diopside with .60ctw round white zircon rhodium over sterling silver pendant with 18" Singapore chain. Measures approximately 1.44"L x 1.00"W. 2.5mm bail. Lobster Claw Clasp. 2" Extender. Accent stones primarily zircon. Everything about it is of the best – the rhodium over sterling silver setting, the white zircons that surround the center medallion-style motif, the floral influence … even the bail is done with elegance. We love the versatility it offers. Pair it with a green velvet at holiday time for a head-turning effect, pair it with a simple sundress in the summertime. Winter, spring, summer or fall, this necklace works — in fact, it works wonderfully. Chrome diopside has several origins, but most of the finest material, and the only commercially viable deposit, is in the Republic of Sakha in Siberia, Russia. As you can imagine, production of this Siberian treasure is sporadic due to extreme winters that last more than eight months. The vivid greens of chrome diopside are a welcome alternative to rare and pricey emerald or tsavorite garnet, but it has yet to gain mainstream recognition due to its limited availability. Minor sources of chrome diopside include Australia, Austria, Canada, Finland, Italy, Madagascar, South Africa, and the United States.
