The trendy lustrous necklace is the work of famous Murano Glass masters, which stands out from the rest thanks to gorgeous colors, swirling patterns, and signature avventurina sparkles. To achieve such effects, the glass-makers employed ancient Sommerso technique, where colored threads of glass are submerged in a layer of transparent glass to create a layered effect. The copper particles infused into the glass while it's still hot create a subtle shimmer inside each bead for a trendy and glamorous effect. Stylish, artistic, and one-of-a-kind, this Italian Murano necklace will brighten up your look and your mood. Give this beautiful Venetian gift to yourself or someone you love. Measurements: The necklace is just over 16 inches long and comes with an elegant attached extender chain. Each bead is approximately 3/8 inch in diameter. The non-glass elements of this necklace are made of 18 kt gold-plated brass for durability, all-day comfort, and an elegant look. This Murano Glass necklace comes with an attractive velvet pouch and a certificate of authenticity. Additional matching jewelry items such as earrings and bracelet shown on some product photos, are NOT included. Because each Murano Glass multicolor necklace is a unique work of art made by hand, variations of colors and patterns will occur. Although each necklace will contain a random combination of colorful sparkling Murano Glass beads, the product photos shown very well reflect the design and the look of this necklace.
