I found these incredibly gorgeous marcasite encrusted necklace accents and I am creating one-of-a-kind designs with each one. From left to right: vintage Swarovski crystal and a gorgeous pinky silvery-gray pearl; vintage Swarovski crystal and a gorgeous, shimmery artisan dichroic glass bead; a handmade Bali silver bead with filigree stripes, a beautifully purple vintage crystal and a jet faceted glass crystal; a twisted glass rod and vintage Swarovski crystals, paired with a freshwater pearl dangle; and an oblong striped handmade silver bead and an artisan glass bead decorated with shimmery dots patterned on the surface of the glass, with beautiful Aurora Borealis sparkle. Please carefully look at the the pictures here; the sterling and marcasite bar is two-sided! The reverse is smooth silver with a heart in the center of the design. I hope you love it as much as I enjoyed making it! The chain is 17 inches long, with an additional extension chain to allow flexibility, up to 21 inches. And I finished the necklace with a beautiful sterling silver clasp in the shape of a heart. One of a kind!
