    My traditional test is to take a bottle straight from the box, and put it against my cheek: glass is always room temperature, while stone (quartz, jade, agate, etc.) is always cold.  The cheek of your face is the most temperature-sensitive part of the human body.
    I learned this test 42 years ago. What is the specific gravity test?
Shabbat Shalom,

Dear Joey,

I went to a jade shop and got to test your theory. The owner's father have retired but was around at that time(lucky day). He took 2 jadeite pendant from the display shelf and put it on my cheek. Guess what! One feels icy icy cold while the other just feel cool. Later found out that the other piece is actually reconstituted from jade powder.

Cheers Joey,
