EUC Mt St Helens Emerald Obsidianite ring in Sterling Silver Sz 7.75/8

I’ve shown the ring on the sizing stick. I would say it’s slightly smaller than an 8. This was purchased at Mt St Helens and only worn a handful of times. One side of the ring is a little crooked but that was how it was at time of purchase. There is minor scratching along the band. The Stone: On May 18, 1980 Mount Saint Helen's erupted with the explosive force of 500 atomic bombs leveling 200 square miles. Thirteen hundred feet of earth was blown from the top of the mountain, sending a cloud of ash more then 60,000 feet into the air and eventually circling the earth. From this volcanic ash and rock is created Mount St Helen's Jewelry, a fused silica similar to obsidian, with the natural color of the evergreen forests that once surrounded the mountain.
