Antique Victorian 10k Gold Agate Cameo Ring Size 5.75

Antique Victorian era 10k rosy gold agate cameo ring. The shank was engraved on the inside but it is hard to read, though I can see that it was a name to another name.
Good condition with typical signs of age and wear. Evidence of previous sizing.
Ring size 5.75
