Silver (925 Sterling) and Onyx Circle Necklace

17” necklace (times 2 for 34” total length). Excellent condition. Has a trademark A on it but I cannot identify whose mark that is. Very classy look. Spend $100 or more and I’ll throw in $50 worth of additional jewelry from my not-yet-listed collection! Check out my other listings, create a bundle and make a reasonable offer. I’ll continue to list new stuff as time permits. Thank you.
