Black Vintage Glass Drop Earrings
We found the mid-century West German Goldfluss glass drops featured in these earrings on our last button hunting trip. Goldstone glass, or Goldfluss in German, was invented by the Venetians in the seventeenth century and is manufactured by heating silica and copper oxide until metallic crystals form.
The production process was perfected by twentieth-century Czech and German glass artisans. Sadly, this trade is uncommon today and Goldstone glass is, therefore, becoming harder and harder to find.
