My guess is this one is over 500 pounds! It is from our mining claim in CCMA. Area is now closed to mineral entry and we have 2 valid claims in CCMA. So we are in the middle of a giant turmoil up there. Anyhow these stones are increasingly rare and very difficult to find. The color is a gorgeous mix of various blues and has white veins of pure crystalline jadeite. These rare jades took millions of years to be shaped by the river.
