Bi-color Amethyst Diamond Pendant

Description This Bi-Color Amethyst Diamond Pendant features a rare 4.13 carat bi color amethyst, expertly cut into an elongated step-cut shape that highlights its natural dual coloration. Bi-color amethyst is a single quartz crystal displaying two distinct hues—purple amethyst and white/colorless quartz—formed through natural environmental changes during growth. Variations in iron content, temperature shifts, and oxidation processes create these dramatic zones, making each bi-color gemstone one of a kind. This purchase also includes one uncut bi-color amethyst gemstone (see image). During formation, amethyst often develops natural color zoning, but bi-color amethyst represents the most striking expression of this phenomenon. The dramatic transition from deep purple to clear quartz is visible from every angle in this precision step-cut stone.   Set in two-tone 14K gold (yellow and white gold), the pendant balances classic structure with contemporary lines. Three natural round brilliant diamonds, tube-set for a modern finish, add subtle brilliance without distracting from the gemstone’s unique character.
