0.62 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes a single transparent, round shape blue sapphire weighing 0.62 carat, with precise dimensions of 4.72 x 4.71 x 3.43 mm, faceted and cut in a mixed brilliant style, clarity graded as very very slightly included when evaluated at eye level, medium color intensity, and an excellent polish. The stone has been heat treated to enhance its color and stability, and it originates from Ceylon, Sri Lanka. The combination of measured weight, exact dimensions, and careful cutting results in a balanced presence that reads as substantial in small scale settings, yet unobtrusive enough to pair with other stones or design elements. The mixed brilliant cut is engineered to optimize light return from both the crown and pavilion, creating a dynamic interplay of scintillation and depth while maintaining a classic round silhouette that adapts well to prong, bezel, and halo settings.

The sapphire’s medium color intensity delivers a vivid blue that is immediately noticeable against metal and skin, without veering into overly dark tones that can mask facet detail. Under daylight and common indoor lighting, the stone exhibits a saturated cornflower to slightly purplish blue hue that remains lively across viewing angles, the hue consistency aided by the mixed brilliant proportions that disperse light evenly through the crystal. This vibrancy ensures the gem will stand out in any jewelry setting, whether mounted as a solitary center stone in a minimalist ring, set within a delicate pendant, or incorporated into a multi stone composition. In white metals, the blue reads crisp and pure, creating a cool contrast that heightens perceived clarity, while in yellow and rose gold the warmth of the metal accentuates the stone’s blue, producing a complementary visual tension that can make the color appear richer and more saturated. The stone’s size and round outline provide flexibility for designers and clients seeking a focal point that commands attention without dominating an overall design, and the excellent polish enhances its surface reflection, ensuring bright, clean highlights that draw the eye.

Beyond color, the sapphire’s clarity and cut contribute materially to its standout quality in finished pieces. The very very slightly included clarity grade at eye level indicates minor internal features that do not detract from transparency or brilliance under normal viewing, allowing the depth of color and facet pattern to remain the primary visual elements. The mixed brilliant cut combines a traditional faceted crown with a pavilion designed for maximum light return, producing both fiery pinpoints of scintillation and broader flashes of color. This combination is particularly effective in small stones, where precision in facet geometry determines whether the gem reads as lively or dull when set. The excellent polish further refines the surface, reducing light leakage and enhancing the crispness of reflections. Heat treatment is a widely accepted enhancement for sapphire, applied to achieve color uniformity and reduce the visibility of minor inclusions, and in this specimen it has been performed to industry standards to stabilize the desirable medium blue tone. The origin of Ceylon, Sri Lanka contributes to the gem’s character, as sapphires from this region are known for their clarity and appealing cornflower to medium blue hues, qualities that are evident in this example.

When considering setting and styling, the stone’s measured proportions and vivid color suggest several effective approaches for showcasing its attributes. For an emphasis on color purity and optical brilliance, a four or six prong white gold or platinum mount will maximize light exposure and allow the mixed brilliant cut to perform at its best, producing a lively face up appearance with clear flashes. For a warmer, more classical presentation, a yellow gold bezel or low profile prong setting will create contrast that intensifies the blue, while a halo of small diamonds can increase perceived size and add scintillation without competing with the sapphire’s hue. The compact 4.72 by 4.71 mm table allows for secure settings in bands, solitaire rings, and stud earrings, and the excellent polish preserves the tactile quality of the gem in daily wear. The Natural Sapphire Company stands behind the factual attributes of this gem, and our description focuses on verifiable specifications that inform design choices and long term satisfaction. Care for heat treated sapphire is straightforward, clean with warm soapy water and a soft brush, avoid harsh chemicals and extreme thermal shock, and periodic professional inspection of the setting will maintain both the security of the mounting and the optical presentation of the stone.
