Hello,

Found these at a Gem & Mineral Show last weekend. Fairly sure the beads are old jade, of white type I'm thinking Old Hetian(?), based on internet images. My question would be, each bead has rough calcium like patches on the surfaces and inside the bead holes. Would this indicate extreme heating or that they were excavated, as I've read soil PH can cause these type of markings. One bead has an extremely weathered surface and a faint 9-eye DZI pattern. It also has these white blotchy patches. This one looks like a greenish/yellow agate. Any thoughts on these beads are appreciated. Excited to string a necklace with them!

Thanks Much,
Kim

I forget which year they started exhibiting in Tucson - ten years ago?

The long bead reminded me of this material.

I would be surprised if the Chinese didn't immediately buy tons.

If you follow some of the other links, you'll find pictures of them helicoptering boulders out of the Nor Cal mine site.

Jade (being a rock) is always old, the cracalature on the surface was probably heat or chemical induced as even after jade calcifies and gets chalky it often retains a smooth or shiny surface. These stones fave been fiddled with.

I have a small piece where the little rounded bumps are quite fine, as in your long bead.

Alas, it has an unfortunate resemblance to a booger. I'll see if I can find it and snap a pic.
