This is a beautiful vintage,  possibly antique brass ring with a lovely goldstone cabuchon in prong setting.  There may be a degree of gold fill as similar pieces are, but not able to confirm

We felt there may be faint makers marks, but there is patina, so not able to confirm

Sz 8.5

Shimmery Copper Sandstone oval is 1/2 inch in length

Goldstone is a sparkly copper stone made of glass

The brass thick filagree setting is amazing

Just over 1/2 inch at the thickest

1/8 inch at thinnest

Patina and age as shown, but overall, beautiful condition

Thanks so much for stopping by!
