Pre-owned. From an estate. Both the butterfly backs and the posts are marked "925". This pair of earrings came from an estate which had a lot of Sundance Catalogue jewelry in it. I believe these may be from that catalogue. Oxidation to silver, so it could use a light polishing. I do not know what the larger pink stones are. One of those larger stones has a couple of chips. These earrings are 2 7/8" long x 3/4" widest. Combined weight is 10.8 grams.
