I made this choker necklace using tarnish resistant 18k gold plated curb chain with an extender that makes it adjustable from 16"-18.5" in length. I added an irregular shaped faceted clear crystal connector in gold, handcrafted from India. There is an 18k gold plated clasp and 24k gold plated connecting rings. * Your purchase will arrive in pretty packaging * Stone Name : Clear Quartz * Shape : Assorted Shape * Size : 15-20mm
