Wow you keep finding different colors! I never realized there were so many. Have you tried tumbling any yet? My tumbler is little & slow, but the apache tears I did a few yrs ago turned out amazing! There were a few that chipped in the process, but all in all it was a very successful project.
Yah, tried to tumble some but it took soooooo long and some did break. Think that since they "come" sort of tumbled anyway most don't really need it. Plus I kind of like the more "natural" look, when they're tumbled they sort of turn out like a lot of "tumbled stones" & not so special. And the ones with the silver sheen are pretty so don't I don't want to loose that. But the uglier ones probably could use a bit of a tumble for sure! lol
