Monceau Green Amethyst Prasiolite & Diamonds Necklace

This 18K white gold pendant necklace centers on a 6.39-carat natural green amethyst, cut in cushion form with an intricate Kord style facet pattern that distinguishes it from standard brilliant cuts. The result is a soft, stable mint-green stone that shifts subtly in tone depending on light and viewing angle—a characteristic of prasiolite that appeals to collectors seeking understated color rather than vivid saturation.

A halo of 30 round brilliant diamonds (0.31 CTW total) frames the 14x10 mm gemstone, amplifying its presence without overwhelming its delicate hue. The white gold surround emphasizes the cool undertones of both the prasiolite and the accent stones, creating a cohesive, refined silhouette. The polished finish and halo-and-cushion setting are hallmarks of high-jewelry construction, with each diamond selected for consistent clarity and brightness to support the central stone rather than compete with it.

This piece suits those who prioritize craftsmanship and gemstone authenticity over trend-driven design. Natural prasiolite is durable enough for daily wear (8 on the Mohs hardness scale) and, unlike synthetic alternatives, develops subtle visual complexity over time. The necklace works equally well layered with other fine jewelry or worn as a standalone statement that reads quietly elegant rather than loud.

The Monceau design balances contemporary geometric setting with classic color theory—a deliberate choice for collectors building timeless collections rather than seasonal pieces.
