Hi was wondering if someone could identify this object and what it is possibly made of, i did think it might be a japanese netsuka but am not sure due to the carved out centre circle as for material am not sure it feels cold to the touch and is heavily stained but did wonder if it might be jade or not.
So…the entire piece is 7cm x 5 cm (2.76″ x 1.97″) with the inner hole is 2cm round x 7mm deep (.78″ round x 0.28″ deep)?
