Vintage Graduated Faceted Disc Rock Crystal Quartz Necklace

Gorgeous design of graduated faceted disk rock crystals with tiny clear pyramid crystal spacers. Strung with heavy threading with a barrel screw closure. Some thread showing on one end at the clasp but shows no signs of breaking or loosening. During my inspection I found a chip in one of the large crystals with hairline cracks. I’ve tried showing the best I could in the photo (last one). It’s hard to see while wearing, you have to pull the crystals up close to see it. Hallmarks: None Measurements: 16” length, the largest disk is .75” diameter and the smallest is 1/4” diameter. Condition: Beautiful vintage condition with noted flaws
