Interesting vintage, mustard, yellow clip on earring’s

Estate sale pick up from consignment client. I do not have information on the composition of materials, or have I tested materials for any specific composition. Please do not bid or purchase if this is an issue for you. All items from the estate have been stored for a long time and may/will have tarnishing, are not in perfect condition, or need cleaning. I do not clean jewelry. I leave this up to the buyer based off of lack of material composition. I took multiple pictures and video on all jewelry. What you see is what you will get. Sold as is, with no returns. That being said some great finds!
