1.57 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One glance at this natural Ceylon blue sapphire immediately distinguishes it from the more common offerings on the market, the majority of which are heat treated or exhibit noticeable inclusions. This gem weighs 1.57 carats and measures 7.11 by 7.05 by 3.94 millimeters, a proportion that results in a depth of about 56 percent, a balanced dimension that preserves both face up color and lively light return. The vivid blue color is characteristic of fine Sri Lankan origin, presenting a true saturated tone without appearing dark or muddy, and the clarity grade of eye clean assures that the color and brilliance are not interrupted by visible inclusions. Many stones of similar weight and color require enhancement to reach an attractive appearance, but this sapphire is untreated, a distinction that makes it rarer and more desirable for collectors and connoisseurs who value natural beauty and long term value.

What truly sets this stone apart visually is its mixed brilliant cut, a deliberate hybrid that combines the scintillation and fire of a brilliant crown with a pavilion geometry that deepens and concentrates color. In contrast to a full brilliant cut which can sometimes leak color and create windows in sapphires, the mixed brilliant approach optimizes how light is managed inside the stone. The crown facets are arranged to break incoming light into lively flashes as the gem moves, while the pavilion facets are angled to reflect that light back through the face in a way that reinforces the stone s blue, rather than dispersing it out of the bottom. The result is a lively play of light with controlled contrast and a strong, even color face up. Excellent polish on all facet surfaces enhances every facet junction, producing crisp reflections and sharp scintillation that you feel rather than just see. Compared to step cuts that favor color but sacrifice sparkle, or full brilliants that favor sparkle but can sacrifice depth of color, this mixed brilliant gives the best of both worlds, a performance that is particularly well suited to blue sapphires where color depth and lively light interaction are equally important.

Beyond optical performance, this sapphire represents superior value when compared to many other market options. An untreated, eye clean sapphire from Ceylon with vivid color and excellent polish is uncommon at this size, and because it is unenhanced it carries the provenance and integrity that discerning buyers seek. The balanced measurements and the careful execution of the mixed brilliant cut mean the stone can be set in a variety of styles and still remain a strong visual anchor for the piece, whether placed in a classic solitaire ring, a halo setting that enhances presence, or a bespoke design where the gem is the focal point. At The Natural Sapphire Company we select and present stones with transparency and gemological rigor, and this sapphire embodies what collectors and gift buyers seek, a naturally vibrant color, crisp optical performance, and long term desirability. If you are comparing options, consider how treated stones may appear more vivid initially but can look artificial or uneven under different lighting, while included stones can interrupt the path of light and diminish both brilliance and perceived color, this Ceylon stone delivers natural, consistent beauty and the kind of presence that matures in value and appeal over time.
