0.46 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 0.46 carat round blue sapphire, measuring 4.61 x 4.61 x 2.92 mm, presents a refined balance of proportion and presence. Origin Ceylon, Sri Lanka, this sapphire is offered by The Natural Sapphire Company, and it is notable for being untreated, with no enhancement. The gem is fully transparent, allowing light to pass through the stone with minimal obstruction, and the combination of size and optical clarity makes it versatile for a range of fine jewelry applications. At 0.46 carats, the stone reads as an elegant focal point in delicate designs, and it adapts well to halo, solitaire, and three stone settings where precise placement and skilled mounting can maximize its visual impact.

The mixed brilliant cut of this round sapphire is central to its exceptional cut and brilliance, making it a true centerpiece in any collection. The cutting style combines a brilliant facet arrangement on the crown with a proportioned pavilion that enhances light return, producing strong internal reflections and lively scintillation. Facet junctions and symmetry are executed to yield balanced light performance, and an excellent polish further refines the interaction of light with each facet plane. The result is a stone that displays concentrated flashes of brilliance when viewed face up, and a pleasing interplay of contrast and brightness that emphasizes the round outline. This precise cutting work promotes efficient light return, which elevates perceived color saturation and contributes to the stone standing out in both direct and diffused illumination.

Clarity and color characteristics of this sapphire contribute substantially to its appeal. The clarity grade is very very slightly included, evaluated at eye level, which indicates that inclusions are minimal and do not compromise the transparent appearance or the gem s optic performance. These minor internal features do not detract from the gem s face up beauty, and they are consistent with natural origin and minimal human intervention. Color intensity is described as intense, providing a vivid blue that benefits from the stone s transparency and polished facets. The overall tone and saturation present a lively, attractive blue characteristic of high quality Ceylon sapphires, with enough depth to convey richness while retaining brightness that reads well in a range of lighting conditions. Because the sapphire has not been subjected to enhancement, the color and clarity are natural expressions of the material, an important attribute for collectors and connoisseurs who prioritize untreated gemstones.

From a practical and design perspective, this 0.46 carat round sapphire offers numerous possibilities as a centerpiece. In a solitaire setting with open prongs, the cutting and polish of the gem will be showcased to best effect, allowing maximum light to enter the pavilion and reflect back through the crown. A halo of fine melee diamonds can increase perceived size and add contrast, while a bezel or low profile mount will emphasize longevity and wearability for everyday use. Metal selection can be tailored to the desired aesthetic, with white metals accentuating brilliance, and warmer yellow or rose tones enhancing perceived warmth and depth. As corundum, sapphire rates high in hardness and durability, suitable for daily wear with sensible care. For routine maintenance, cleaning with warm water, mild detergent, and a soft brush preserves surface luster, and periodic professional inspections of the setting are recommended. The Natural Sapphire Company can assist with bespoke mounting, fitment, and recommendations for care, and is available to provide additional documentation on origin and treatment status upon request.
