Purchased from the diver himself, who harvested this and other naturally ocean worn Jade, from out of the Pacific (off Big Sur). You can see from the photo, the gentler color, but without good lighting, it is all darker (like the top left in this photo).
Over 3/4 of a pound of honest and true Nephrite Jade, polished beautifully into a large palm piece!
Sold to me as a gem quality green Kyanite (which I can't imagine it being), it was mined elsewhere and carved in India. Looks just like Nephrite Jade, minus the black spots. It could also be a very high quality Serpentine. The translucency is exquisite, looks like green ocean surf! Highly recommended (and good sized)specimen!
