2.10 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent yellow sapphire weighs 2.10 carats and measures 8.51 by 5.95 by 4.17 millimeters, presented in a radiant shape that combines trimmed rectangular proportions with step and brilliant style facets. The stone is graded at very slightly included at eye level, indicating clarity that reads clean to the unaided eye while retaining minor internal characteristics visible under magnification. Color is described as medium intensity yellow, a saturation that balances vivid presence with sufficient transparency to promote lively light return, and the surface finish carries an excellent polish that maximizes mirror like facet surfaces. The sapphire has been heat treated, a stable and widely accepted enhancement that refines color and clarity without compromising structural integrity. Origin is Ceylon, Sri Lanka, a historic source noted for producing sapphires with a characteristic luminosity and clean tone. The Natural Sapphire Company presents this example with straightforward documentation of its measured dimensions, weight, cut, clarity grade, color intensity, polish, treatment, and origin, enabling objective assessment and comparison with other gemstones.

Optically, this radiant cut yellow sapphire displays the hallmark attributes of corundum, namely a high refractive index and a strong vitreous lustre, which together deliver good brilliance and crisp facet contrast. Compared with blue sapphires in the same weight range, the yellow tone here absorbs less blue and near ultraviolet light, and consequently often reads slightly brighter under mixed lighting conditions, producing a more open appearance and faster light return, particularly when the medium saturation keeps absorption moderate. Relative to deeper or more saturated sapphires, this specimen offers improved scintillation because the lighter color permits greater internal reflection through the pavilion facets. When contrasted with other yellow gemstones that occupy a similar market category, such as citrine, yellow topaz, and yellow beryl, the sapphire stands apart through superior refractive properties. Citrine and beryl have lower refractive indices and therefore exhibit softer brilliance and less distinct facet reflection. Yellow topaz presents more noticeable dispersion based color flashes on occasion, but it lacks the combination of hardness and enduring polish retention that corundum provides. Compared with diamonds and other high dispersion gems, sapphire displays less fire due to lower dispersion, however the radiant cut and excellent polish focus attention on clean, white light return and sharp facet delineation, qualities prized for colored stones. The Sri Lankan origin contributes a particular clarity profile and a clean, luminous yellow that emphasizes evenness of tone across the table and crown facets.

From a practical and gemological perspective, the radiant cut and excellent facet execution of this 2.10 carat sapphire create predictable and dependable reflective behavior when set in jewelry, the strong polish preserving crispness of highlight and contrast, and the medium color intensity ensuring balanced light return across varied lighting environments. The stone’s very slightly included clarity classification indicates that it will maintain its visual integrity in typical wear, while the corundum hardness provides substantial resistance to abrasion and facet wear, making it suitable for frequent use in rings and pendants. Heat treatment reported here is stable under normal wear and routine jewelry care, and does not require special handling beyond standard precautions for any fine colored gem. When evaluating reflective qualities for design decisions, consider that the radiant cut emphasizes both broad flashes from its trimmed outline and lively scintillation from its pavilion faceting, a combination that complements the inherent lustre of sapphire more effectively than some mixed cuts which prioritize either facet contrast or overall brightness alone. The Natural Sapphire Company documents each characteristic to assist in technical comparison and to support informed selection, focusing on measurable qualities such as dimensions, weight, clarity grade, color intensity, polish, treatment, and origin, rather than promotional language, so that the gem’s intrinsic optical performance can be judged on its own merits.
