Is that graveyard material? I can’t quite tell, but it looks like the plumes are breaking through the surface.

Rock is huge, plumes all over the place. I can’t speak for others, but myself personally, plume or moss that breaks the surface is no good. Specifically for the reasons that it doesn’t allow for a polish when cutting cabochons where it breaks through and also has a tendency to under cut because it’s softer than the material it’s hosted in. That doesn’t mean it’s not worth anything. But for lapidary purposes, it wouldn’t be highly desirable. Can’t count the number of times I’ve found new material, cut it, then find the plumes/moss are too soft to work with. It commonly happens. |

Always something to be learned here! Thanks for the input realrockhound. Maybe this material is too plume-y... |

Graveyard Point Plume can be silica infused even if it breaks the surface and can polish as well as the agate itself. I'd polish a piece on wheels or in a tumbler and see how yours does.

Sabre52 that sounds like a great idea, I'm not sure why I didn't try that yet. Lol.

It's definitely GYP plume. I've polished many cabs of this material and while the white plumes tend to be opal I suspect there's enough silica infusion to prevent undercutting. Not sure what mineral the black plumes are, probably manganese, but I've never had problems with them either. |
