Vintage Stone Ornate Pendant Necklace

Vintage Stone Ornate Pendant Necklace. Unsigned gold tone. Pendant has been added to a continuous strand chain with no clasp. Polished stone looks like some type of quartz or agate. I see a tad of sparkle within some of the stone with a loupe. Condition is good except there is some type of small glitter spill ( Nail polish perhaps ? ) on the back of pendant. A miniature mannequin is used for photos. Red Jewelry box is not included. 3781
