Thank you. What I think you have is a silver set with amethysts.From around 1930-40s. A market valuation is approx. $200. But I would go past a jeweler for a second opinion about the stones. The might be synthetic.
I hope this information was helpful!
I am happy to answer follow-up questions.
If you want to sell your item then here are a few suggestions:
Facebook Marketplace, NextDoor.com, Webstore.com, Varagesale.com
GoAntiques.com, Truegether.com, Mercari.com, Wanelo.com, Poshmark.com, Bonanza.com, Etsy.com, eBay, Pamono.com, and Chairish.com.
If you have several jewelry items then start a new thread/request per item. If you write
'FOR ANNA' in headline the question comes to me.
I strive to always provide five-star service, please let me know if you like more information about your item. As the assessment is made online and with the reservations and uncertainty it provides, I would recommend a physical assessment before a possible sale.
