I saw the photos of your visit to the stone carvers. I'm sorry to hear of the lossy of our dad. I lost lost mine last year.

I will be in the process of taking photos of the raw material in the near future. Also will be digging out cut slabs and polished material, it's all under a ton of crap in the back of the garage. Nepherite is between 7-8 on the mohs scale, much harder then oriental jade and diamond tools work best for cutting and grinding.
