While classifying some material for the sluice, I found this river washed stone that is quite heavy. It's a little larger than a golf ball, elongated. I could see some reddish/pinkish translucent material in the black/yellow matrix. I decided to cut a cross section from it. The cross section is about 1/8 inch thick and my photo is blurry, but the translucent material color is accurate. Any ideas?

Yes, I recognized it.... you think it's Garnet? You should do a Simple Specific Gravity Test. That would help narrow things down.

My Grandpa back in the 50's worked for the Montana Highway department, they were building a road somewhere in the Mountains, and he told me when they cut into the mountain side, there were 4 foot long individual quartz crystals, too heavy to even pick up. He did have one that was about a foot long. Wish I knew where it was exactly. |
