The banded sardonyx beads measure 6mm each. The agate spikes graduate from approximately 21mm-27mm in length.
This necklace measures approximately 16 3/4 long in overall wearable length. It is in EXCEPTIONAL antique condition!
Three of the agate spikes have small insignificant chips to the tips, and one has a flake on the side. This is highlighted in the last picture. This is all very minor, to be expected from age and use, and not noticeable unless you look for it. This is an absolutely FANTASTIC piece! The spring ring clasp is hallmarked 14K gold.Please feel free to ask any questions you might have, and be sure to check out my other GREAT items!
