This 2.10-carat natural dark blue sapphire gemstone is cut in a rectangular shape with beveled corners. Measuring approximately 7.4 mm in length by 3.8 mm in width, the gem presents a dark blue hue with consistent saturation across its structure. The elongated shape, combined with precise faceting, enhances light reflection along its surface, creating controlled brilliance while maintaining the depth of color.

The absence of artificial enhancements in this gemstone ensures the integrity of its natural formation, shaped by geological processes over millions of years. Its dark blue tone remains steady under varying light conditions, with a deep, inky quality that absorbs and reflects light in a subtle yet defined manner.

The rectangular cut allows for versatile use in jewelry, particularly in settings that emphasize clean geometry and symmetry. Its proportionate balance of length and width gives it a refined structure, suitable for designs that require a linear or step-cut aesthetic. 

This sapphire is a fitting choice for collectors or designers seeking a naturally formed stone with well-executed faceting and a rich, unaltered color profile.
