Van Gogh said that cobalt is the most divine color and I have to agree! This gorgeous, cobalt blue stained glass is hand cut stained glass and made in Tiffany style with copper foil and lead free solder, finished with black patina for an antique look. The earrings are texture facing out. They weigh in at 5 grams a piece, and have .925 sterling hooks. For reference, a US quarter coin weighs 6 grams. My pieces are all hand cut glass, so there are slight irregularities that provide artistic uniqueness.
