Subject:Need help identifying Chinese Jade (?) Bowl
Posted By: Humberto Thu, Jun 16, 2016 IP: 84.126.82.137

I need any information you may have about this Chinese bowl. Its dimensions are 20 diam x 10 ht cm (7.9 x 3.9 inches). Thank you.

The chance of this bowl being made of real jade such as Jadeite or nephrite, IMHO, is close to none. A very modern bowl that was made of soft stone. Sorry.

It looks like the "carving" was done with acid, DID YOU DO THE SCRATCH TEST? The "dirt"was added to make the bowl look old.

Thank you for your reply. Yes, I did the scratch test with the tip of a fine German steel knife. It did not scratch it. Which means the Mohs hardness must be 6 or above.

Do the symbols on the bottom of the bowl have any significance?

You need to do a 2-3 mm scratch, with enough pressure to see a tiny scratch. Then tell us if it is a white or black scratch

I first tried the tip of a steel knife, could not scratch even with pressure. Then tried the tip of a hardened steel scissor, made a white scratch.

Sorry, test failed,,, it is Serpentine, which is softer than Jade.
