2.33 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent yellow sapphire from The Natural Sapphire Company is a carefully documented gemstone, weighing 2.33 carats, with an oval outline and dimensions of 8.70 by 6.67 by 4.53 mm, presented in a mixed brilliant cut and finished to an excellent polish. The clarity grade is recorded as very very slightly included evaluated at eye level, which translates to minimal internal features that do not detract from the gem when viewed without magnification. Color intensity is described as intense, producing a vivid and saturated yellow field that remains consistent across the pavilion. The stone is beryllium diffused to enhance and stabilize its yellow hue, and its reported origin is Ceylon, Sri Lanka, a source known for producing sapphires with notable color purity and lively transparency. These technical details reflect the specimen as a gem with substantial presence for its carat weight, and an overall balance of cut, clarity, and color that supports versatile use in fine jewelry.

The mixed brilliant cut employed for this oval sapphire combines step cut facets on the pavilion with brilliant style facets on the crown, an arrangement that optimizes both face up color and internal light return. The crown facets disperse light into small flashes and contribute to scintillation, while the pavilion facets redirect light back through the table to reinforce body color and brilliance. Because the stone is transparent and carries very slight inclusions, light travels cleanly through the material, enabling crisp facet outlines and well defined flashes. The excellent polish enhances facet contrast, increasing the perceived sharpness of reflections and the overall visual impact. The beryllium diffusion treatment produces a more uniform and intense yellow than would be present in some untreated material, resulting in even saturation across the table and shoulders, while still allowing the structural cut to define brightness and sparkle.

Observing this sapphire under different lighting conditions reveals complementary aspects of its optical character. In natural daylight, particularly bright mid day sunlight and cool outdoor light, the gem displays a fresh lemon to sunflower yellow, with high clarity and lively scintillation where the mixed brilliant crown facets create micro flashes. Under warm incandescent light the color temperature shifts toward a richer golden hue, deepening the body color and giving the sapphire a warmer, more opulent appearance, while preserving crisp reflections from the excellent polish. Under modern LED lighting the presentation depends on the lamp spectrum, with broad spectrum white LEDs rendering a balanced view that highlights both saturation and brilliance, while cooler blue biased LEDs may increase perceived contrast between bright flashes and body color. Fluorescent light tends to flatten extreme color temperature shifts, showing a steady intense yellow and strong internal light return. In low light and candlelit environments the stone retains depth and glow, with the pavilion structure producing concentrated flashes that read as sparkling warmth against the darker background.

For use in finished jewelry, the combination of size, cut, clarity, and color makes this 2.33 carat oval sapphire suitable for a variety of settings where both color and light performance are important. A setting with an open head or a well designed bezel that exposes the pavilion will allow maximum light entrance and return, emphasizing brilliance and scintillation, while a warm metal such as yellow gold will harmonize with the intense color and increase the perception of depth, and a platinum or white gold mount will contrast the yellow for a cleaner, contemporary presentation. The very very slightly included clarity at eye level indicates reliable stability during setting, and the excellent polish ensures the stone will present crisp reflections across angles of view. Routine care is straightforward, using mild soap and water with a soft brush, and avoiding harsh chemicals and extreme thermal shock to preserve the diffusion treatment and surface finish. The Natural Sapphire Company documents the important attributes of this sapphire including the beryllium diffusion and Ceylon origin to ensure transparent communication about its provenance and enhancement history, providing a clear foundation for responsible selection and long term enjoyment.
