This gorgeous,deep blue Waterglass stained glass is absolutely stunning in the light! They are hand cut stained glass and made in Tiffany style with copper foil and lead free solder, finished with black patina for an antique look. They weigh in at 4 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.
