This unique sterling silver necklace is stamped with the artist's initials in the back of the pendant. It measures 1.5 inches tall by 1 and one eighth inch wide. The center stone is aventurine, and the beads of the necklace are amber, malachite, lapis, hematite, blue topaz, jasper, black and white onyx, and many more that I can't identify. The necklace measures a dramatic and generous 24 inches long, and closes with a toggle clasp that is also sterling. Wow! What a treasure! While the history is not known, I believe this piece is Native American made-generally, Native American artists initial their work as this one is. This is an exceptionally beautiful work of art. The necklace that you see in the photo is the actual necklace you will receive.
