Need to sell 400 lbs. (200 each) of Natural slab style cut Green Jade and White Nephrite!!!?

I acquired it from Mingʻs about 20 years ago-a prominent jeweler who made their own jade jewelry in Hawaii for decades. The pieces are mostly in slab form, about 1/2" in thickness and measuring anywhere from 4-8 inches on anyside-most in more or less a square shape. I need to sell it and havent had much luck with cold calling jewelry stores.
