Garnet, Marcasite

vintage GARNET necklace Sterling Silver 925 Czech 2 oz. sparkly Marcasites 17.5″

I pulled this out of my jewelry box. i bought it to impress a Czech guy i knew. Didn’t pan out. So here it is. nice 17.5 inches long. fold over clasp with hinge. solidly built. heavy loops. nice prongs. i should have cleaned it. the marcasites are sparkly. the Garnets are very sparkly. tear drops and round designs. complete. nice. will be protected in shipping. it weighs 2 1/4 ounces. What is the silver value today?
