Hi everybody! A family friend who is in his eighties,(his wife fixed-up me & my wife), Gave me some jade he collected in the late 1960's to early 1970's. The place he collected it is called Patrick's Point located in Northern California. It is supposed to contain the only black jade is CA? Something like that. He says it's quite rare and he's only found a few dozen small stones in the 10 years he looked for it. Here's the stones. They are tough to polish since I learned on agates. #1  #2  #3  #4  #5  #6  #7  #8  #9  Wow, the black ones were tough to photograph. Thanks for looking |

A friend of mine collects that stuff it's called chloramellenite (Spelled wrong) It's supposed to be black jadeite. He gave a few pieces and they'er all round and about 3 inches wide. I haven't worked the stuff yet, after seeing yours I will try some. Nice cabs you made from the material.

I like the soft round shapes of these cabs, and the shine you put on some of them is amazing. Very nice material.

Howdy fishenman, Great job on some fine looking jade! Actually jade occurs up and down much of the California coast from Ventura County north. Patrick's Point is very far north in California being almost to the Oregon border. I've been there but never was lucky enough to find any. Black jade does occur at Porterville in the Sierra Nevada foothills. One form is quite black while the other is actually very dark green so it appears almost black. Another dark green almost black jade occurs near Coulterville in Mariposa county but it tends more toward dark gray/green. Black jade with magnetite also occurs near Victorville on the Calif desert. Your cabs are really nice looking and appear very homogeneous and free of the softer inclusions which make some of the other California jades somewhat problematic.......Mel

Black Jade also occurs near Paradise in North Central California.

Thanks so much everybody. The soft round shapes came out because I cabbed beach tumbled stones and went with the natural flow. Nephrite, Mel and bobby1 great info on this material. I don't know why they won't completely shine up  . This is my first time working jade and I tried 3 diff. methods. I just want a  worthy shine. First I went with all my wheels on the Genie followed with tin oxide on leather. The shine was nice but full of tiny white specks of polish. Second I tried going to just the 600 nova and tin oxide, about the same. Third I went through all the wheels on the Genie then soaked them in mineral oil. I would like to get them shinier but I'm not sure how. Any thoughts? In my original post I forgot to say that these are cabs I am cutting for my friend they were not given to me. Thanks again, Geoff |

Nice job. Some people would say to try chromium oxide, but I've had good luck just using diamond paste on leather. I've been up to Patricks cove, it's really nice up there.

I've heard chromium oxide too but have had good luck with optical grade tin Oxide myself. I think the stages before the polish are very important and those who really get a good shine have told me to sand with very worn silicon carbide belts and not use diamond as the diamond really tears at the fibers in the jade causing a minutely pebbly texture that is harder to polish....Mel

I would second the info on the very well worn 600 grit S/C belt, but do it dry and don't worry about the heat buildup. I do all of my Nephrite cabs this way.
