Nephrite jade that’s specific gravity is 2.57g/cm3

[BillKao]

I bought a small piece of nephrite jade from 324 Castro Street, Mountain View. When I returned to my home, I did test, the result is 18.71g/7.28cm3=2.57g/cm3.
This piece is a real nephrite jade?

I am sorry, that is wrong place for my post.

Welcome to Tnet.

This is something you could easily look up for yourself via Google. At 2.57 g/cm3 (equivalent to Specific Gravity) it doesn't fall within the range quoted by the International Gem Society: 2.90-3.02 and usually 2.95.

It doesn't correspond to the other form of "jade" either (jadeite), which would be a little higher at around 3.30-3.38

Why not post some nice sharp close-up pictures, although that won't necessarily help in identification?

I'm sure the Mods will move your post to a more appropriate area than the "Help" section for technical problems with the forums.

nephrite jade is not precious

I like to learn how to identify rocks and minerals. Real jadeite is precious. Some stores sell serpentine as jade.

Quality serpentine can closely resemble both Jadite and Nephrite. In comparison, it has both a lower specific gravity and is softer.
