Our Champagne Bubbles Necklace features 5mm 14kgf Mermaid Bubble Beads placed throughout a gorgeous row of natural Champagne Topaz stones. Top grade, natural 4-5mm Champagne Topaz is extremely hard to get our hands on in this size and cut. We love the details in this minimalist necklace that gives it a little extra "punch". This 18" necklace is made of 14kgf metal (including the 14kgf Mermaid Bubble Beads) that won't tarnish, fade or peel!! Wear alone or layer with others (Second pic).
