Estate sale pick up from consignment client. I do not test materials or clean the jewelry. I leave it this up to the buyer. All items from the estate have been stored for a long time and may/will need cleaning and are not in perfect condition. Some may be missing pieces, or parts or have spots of tarnishing. Some are vintage and some are costume. What you see is what you get. I took multiple pictures and video on all jewelry. Sold as is, with no returns. That being said some great finds!
