Rare chinese antique stamp/seal maker possible jade

Hello,
I am not finding anything online but I think its like a seal very heavy for its size. Would anyone be able to translate this? I have two files below. Thank you for any help.

 

Picture of the whole item will be needed

 

"Heavy for its size" - How big and how heavy, please?

 

Hi, the second photo looks like a cash coin.

Thank you for your replies. Attached is another image. The size is about 4" x 2.25". Thank you for any help!

 

It could be Shoushan stone or one of the many stones used for carved Chinese chops. As far as being "rare",there have been millions made.

let's give @Asian Fever , a shout out..

 

As the photo komo posted shows, it is not rare or antique. It is handmade though. Most are made for tourist trade/export.

 

Agreed; bought one for myself in Taipei. "Made to order" for your own name.
