I believe all seven rings are about a size 8 or approximately 18 mm across. The patterned ring is slightly smaller and the thinnest gold band with stone ring is slightly larger.

All are gold tone in color.
The oblong black stone ring is marked AVON as is the gold tone patterned band.
3 with clear faceted stones and one with three tiny stones.

Ring box is not included. 

From an estate. I will be listing more jewelry and am happy to combine shipping on purchases made within 7 days and PAID for at the same time.
