Highly Sought After and Collectible, Antique Circa 1920s Venetian Boro Glass Necklace. These beads are generally sold individually because it's hard to find them still on original Necklaces. I just happened to find a couple of these in a Great Estate sale, many years ago. These are so Beautiful and Unique. The chain is Brass. This Treasure measures 31" long and goes over the head. The Pendant measures 1.25" including bail. ALL in Excellent Antique condition. The Depth and Richness of these beads cannot be overstated. You'll LOVE this Rare Heirloom Quality Treasure.The invention of borosilicate glass is usually credited to Otto Schott, a renowned late 19th century glassmaker. It was apparently first sold under the name 'Duran' in Europe in 1893. Item I52. I've been in Vintage/Antique jewelry for over 35yrs and I sell some new items occasionally.
