Triangular Amethyst Cocktail Ring in 14k Yellow Gold. This striking cocktail ring features an 8.48 carat purple amethyst in 14 karat yellow gold. The amethyst reflects colors of dark lilac and lavender. The triangle-shaped facets on the gem glitter and glisten against the warm-tones of the 14K yellow gold ring. From the profile, an openwork mounting showcases the underside of the stone, finished on an ornate and adjustable 14K yellow gold band.
