Obsidian Emerald with Marcasite Ring

Obsidian Emerald with Marcasite ring set in (nickel free) sterling silver. Marcasite is a dark silvery stone mined in Switzerland and used here as an accent stone to give an overall vintage look to the ring. This setting is available in sizes 5-10 and a variety of other colored gemstones. This stone was formed during the eruption of Mt. St. Helen and is also referred to as Helenite. A great option for the May birthstone.
