Best Sterling Silver Peruvian? Pendant

Product Name: Best Sterling Silver Peruvian? Pendant
Sterling silver circular rainbow pendant. Probably Peruvian. Pendant is marked 925. Chain is 18", pendant is 1" x 3/4". I'm not sure about the stones-possibly includes mother of pearl. I love making bundles! See my other listings for more vintage jewelry and other cool stuff! Items are used and vintage. Some wear and tear is to be expected. Feel free to ask for more pictures before buying. Everything is cleaned in a sonic cleaner with water (except for fabric and natural materials). Metal items are not polished. Please let me know prior to purchase if you'd like me to polish it and I can adjust the price. I use PEEK. Polishing is an additional $5. Thanks for looking! North Shore best Aloha Vintage.
