Great old Victorian watch Fob in 9K yellow gold. I tested the metal, and it is 9K. Faint hallmarks on the edges for 9 375. I can see other hallmarks that are very faint, not readable for my old eyes. On one side of the Fob is a fine Bloodstone, the other side a Carnelian stone. Both stones are almost 3/4" round. The Fob swivels, and the top has a step design. The Fob measures 1 1/8" from top to bottom. Weight is 5.5 grms. Condition is very good. With a 10X loupe I see a fine crack running through the bottom of the Bloodstone, but when I run my finger or nail over the small crack I don't feel anything. I don't think the crack interferes with the integrity of the stone. Small edge bites to both stones. I would date this great Fob at c 1860's-80's.
