Dear Steven
In my experience, the jades turned that black are to be seen from Six Dynasties, caused by the use of heavy mercury from the dead bodies. Mercury was used instead of expensive cinnabar for maintaining the dead body for long days of Chinese funeral ceremonies. May be the burial environment have high mercury ore in the earth.
Your rings are donut-like, thick with inner and outer smooth convex adges, the craftmanship is not delicate as Hongshan made. The stones are not of Hongshan quality. It would be later period not of Hongshan, but I think it is nephrite and it is authentic.
It has pitts, red cracks from iron inclusions. And it has no trail of acid treatment as well as artificial whitening. Nice simple piece.
look ar style, stone, craftmanship, as well as evidence of age. I assumed that these 2 pieces are of the Qing Dynasty.
I may be wrong.
Have fun
