Freshwater button pearls. Middling luster. $9.99 would be good if you could get it on eBay. The earrings are blurry, but probably about the same. I would start them @ $4.99 and have the lowest postage possible. $9.99 on Etsy. They just aren't special. I would take them apart and add gemstone beads in between each pearl. Actually, point the pearls to face each other with a gemstone inbetween and a smaller one between the backs.....
Better yet, use them to make dangle earrings. The shapes are better suited to earrings.
