1950s Vintage Blue Aurora Borealis Crystal Cluster Clip Earrings. Magnificent colors bursting forward with each movement. Dazzling and stylish, excellent for any occasion. Many of the jewelry items listed are antique, vintage, and/or pre-owned. Items have had a life before I found them. Items may show evidence of that previous life; signs of wear, dents, scratches, oxidation, or broken stones, etc. I strive to be accurate & transparent in the descriptions of these pieces. I'm not a gemologist. I choose pieces based on their overall aesthetic & how well they accessorize. I try my best to accurately describe the stones in my jewelry items, but cannot absolutely guarantee them. I want the true age of the pieces to be represented, so I do not perform any type of cleaning or polishing. If the item is oxidized when I acquire it, that is precisely how you will receive it.
