Mount St. Helens earrings in solid 14K gold.
What the stone is. Volcanic ash from the 1980 eruption, fused under heat into a green gem material. It is not a naturally occurring mineral — it exists because of one specific day in Washington State.
Why people buy it. Mostly as a piece with a story attached, which is unusual for a gemstone at this price.
