DSC_0843_Humboldt Coast jade cabochon
I collected and cut this years ago (there should be another 1-cab slablet or two somewhere, but it was a small cobble) on Agate Beach, at the recently renamed Sue-meg State Park.
While it doesn't look like typical California Coast jade (nephrite), it does seem to be a rare piece of jadeite. It polishes like it, makes slightly "foamy" swarf like jade, and has a specific gravity of 3.32 -- right smack-dab in the middle of the jadeite range.
It is primarily white jade, with some dark green. The yellow in the healed fractures may or may not be jade
