This gorgeous vintage glass is one of my favorites! I acquired it in an estate collection, so these earrings are limited edition. The glass almost looks black and iridescent until light passes through and then you get the beautiful green light refraction! These earrings are hand cut and made in Tiffany style with copper foil and lead free solder, finished with black patina for an antique look. The earrings weigh 6 grams a piece and have .925 silver hypoallergenic hooks. For reference a US quarter (coin) weighs 6 grams.
