Vintage Cashmere and mink cardigan sweater

Gorgeous cashmere and mink vintage cardigan from the 1950s. The clasp is original made with aurora borealis glass in a half moon shape. Two stones missing. There are also single matching jewels on each sleeve at the wrist. The mink collar is not detachable. The stitching has come undone at the hem on the right side of the sweater about 4” long. Could easily be repaired with a needle and thread. This sweater is approximately a modern size 4-6. The tag inside is hard to read. I don’t see a size. It does say imported cashmere. Excellent condition. No stains or odor. Sleeve length 22.5 Top shoulder to bottom edge 20
