Heavy sterling silver and Malachite ring. Malachite is a popular stone which has light and dark green banded areas.
The inside of the band is hallmarked STERLING on one side and 14K and something I can't make out on the other side.
I would guess this ring to be about a women's size 8-9, measuring approx. 2.5 inches around.
The stone is large, measuring 7/16ths inches across.
Condition is excellent.
No reserve. US shipping $7.00

 

Marked only STERLING, hand worked bar pin. C clamp. Measures 2 3/4 by 1/4 inches. No reserve. Shipping $6.00  

Very well made heavy sterling silver bar pin. Measures 2 3/8ths inches long by 3/4 inches high by 1/4 inch thick. It is a rounded thickness towards the center for a 3D effect.
Marked 925BA.
Moving clasp works well. (Not the older plain C Clamp, seen in the Arts and Crafts jewelry, so it is later than that period, but I don't know exact vintage.)
Condition excellent. Original patina. I have not polished, though there is some tarnish on the back that could be polished.
No reserve. US shipping $7.00
