In this video i cut and polish a piece of helenite volcanic ash gem material.
This comes from mt st. helens volcanic ash after the eruption of the volcano in 1980.
Different additives can give the material different colors. The one i used is the green variety. Thanks to john c for sending the material.
Helenite cuts and polishes easily, i used a darkside lap and cerium oxide to polish it.

This loocking so good!
I’m living in Czech Republic and this stone is Moldavite from CZ?
I have some collection of this stone’s, but in original!

Super nice job man..is there any way I can have you facet a couple stones of mine 🙏🤙

@tamwolf20 5 years ago

Beautiful cut Brent. I do have a question about the bubbles in the material. Did you have any issues with the bubbles breaking through on a facet and creating a dibit in the facet face?
Another wonderful video. Thank you Brent.

Been wanting an ultratec for 7 years... long before they became all all rage in the glassblowing industry.. every time I get the money almost there... life happens. I get much vicarious enjoyment from watching you work. You seem to treat your machine right- it irritates me to no end to watch other glassblowers abusing machines that I can't afford. They let swarf dribble down into the quill, and get filth accumulate all over the mast, etc. 😂
