Original material from the Paulsen family who had the patent for this material.

Helenite is created from the ash of the May 18, 1980 Mt. St. Helens explosion!  It’s historical rough that's a great conversation starter and cuts gorgoues gems⁠.⠀⁠⠀

It’s a really nice facet grade glass that cuts pretty gems and this teal is to die for.
