Zimmi Diamonds

Zimmi Diamonds are among the rarest natural treasures in the world, revered for their unrivaled intensity and the most saturated golden hue of all yellow diamonds. Representing a mere 0.001% of all Fancy Vivid and Fancy Deep Yellow diamonds, they are extraordinarily scarce and sought after by the most discerning collectors.

Exquisite Hues

While the majority are graded Fancy Vivid Yellow or Fancy Deep Yellow, some reveal exquisite secondary hues: delicate inflections of orange, green, or brown adding layers of character and individuality.

Unmatched Rarity & Premium

Though the GIA grading scale does not separate saturation levels within the Fancy Vivid category, the distinction of Zimmi’s color is unmistakable to the trained eye. Their radiance is so exceptional that Zimmi Diamonds command a world-class premium. Universally classified as Type Ib, they owe their remarkable intensity to rare nitrogen impurities, a scientific rarity that translates into unmatched beauty.

Origin

Born in the rainforest-rich Zimmi region of Sierra Leone’s Pujehun District, along the Liberian border, these diamonds are unearthed through traditional alluvial mining by local communities. Each stone is fully traceable and certified under the Kimberley Process, guaranteeing their conflict-free provenance.

Exquisite, rare, and steeped in heritage, Zimmi Diamonds are jewels of legends, an enduring expression of rarity and refinement available only through the most trusted names in the world of luxury.
