Double Style Bench Bead Vintage Sterling and Turquoise Choker Necklace. I started collecting genuine turquoise and sterling jewelry years ago, before it was cool. This handcrafted piece is made of sterling silver and high grade Blue Gem Mine Turquoise. It is heirloom quality and really needs to be seen. This choker style necklace is 16" clasp to clasp, an extender could easily be added to make the necklace more adjustable. It has beautiful patina but could be polished to a high shine if so desired. A beautiful necklace worn alone or layered with other native pearls of varying lengths as the focal piece. This piece does not carry a maker's mark.
