INVESTMENT AND JEWELRY POTENTIAL:
Appreciation: Prices of fancy-color diamonds show a strong, long-term upward trend, significantly outpacing the price increases of colorless diamonds.

The exceptionally complex, multi-tonal color composition—featuring visible shades of green, gray, and yellow (Fancy Dark Greenish Gray Yellow)—combined with its impressive weight of 1.51 carats, makes this piece unique and gives it high collector’s value.
Application: The elegant and traditional emerald cut beautifully showcases the stone’s unique, multidimensional color. It is perfectly suited as a durable and stable investment or as the centerpiece of luxury custom-made jewelry. Setting a stone with such rare characteristics significantly increases the final market value of the entire piece.
