I bought this archer's ring that was a whitish/beige color. It looked like either ancient or fake calcification, I'm not sure, but there appears to be no pitting. I tried cleaning it off, but I haven't been too successful.

Now there are still white parts, though the ring looks mostly greenish black now. However, a translucent green is starting to show through.

Obviously without seeing the before shot it's hard to get an opinion, but what does the forum think, a new ring made to look old or an actual old ring?

Any thoughts on how to accelerate the removal of this film?

Thanks!

Dear Jack

I do not understand why the 1st picture have metalic lustre, but the other 2 pictures do not have.

Correct me if I am wrong, I noticed that the 1st picture show drilling marks on the surface which unlikely found on authentic jade thumb ring.

After careful observation, it looks like ancient glass instead of nephrite. Glass is hard, too. It may pass needle pecking. You may perform SG test to know what exactly it was made of.

And fakers can fake anything on jade.

The metallic look can be attributed to the flash of the camera going off and making the area exposed in the middle look metallic. It is actually black and smooth there.

I will have to do a specific gravity test, but the hardness seems to be a five. Weight was 1.4 ounce = 39.6893324 gram.

Calcification is artificial and can probably be washed off (but I advise against it).

It is unlikely that it was made of nephrite jade. It is simply too transparent. If it is made of jadeite (which can be that translucent) then there should never be such severe calcification found on it (due to its hardness and high S.G.). Therefore this piece is most likely made of serpentine with a low possibility of being made of jasper. A hardness test and a S.G. test will confirm the material.

Difficult to say, but surface alteration doesn't look natural, real antique surface calcification would take very long time to disappear.

Also this type (shape) of archer's ring correspond to recent period of time (Qing dynasty at most) therefore it shouldn't show much calcification...
