1.77 ct natural cushion-cut Ruby, showing a rich, saturated red that draws the eye even under low light. Cut to 6.46 x 6.25 x 3.83 mm, the proportions were chosen to balance color and brilliance rather than maximize weight alone. This stone is untreated — no heat, no fillers, exactly as it was mined. With a hardness of 9 on the Mohs scale, an excellent choice for rings and other everyday jewelry.
