0.46 Ct. Chrysoberyl from Ceylon (Sri Lanka)

This 0.46 carat oval chrysoberyl from Ceylon is a study in precise lapidary control and classic material pedigree, presented by The Natural Gemstone Company. The gem measures 5.20 by 4.09 by 2.75 millimeters, producing a length to width ratio of approximately 1.27 which sits squarely within the preferred range for oval proportions, and a depth percentage of approximately 59 percent which indicates a balanced pavilion and crown relationship that optimizes light return. The stone is cut to a mixed brilliant scheme, where a brilliant style crown with multiple small star and kite facets meets a modified pavilion geometry designed to preserve weight and saturate the face up color. The cutter maintained crisp facet junctions and an even girdle thickness, evidence of careful preforming and final symmetry control, resulting in an excellent polish that enhances the gem s inherent adamantine luster derived from chrysoberyl s high refractive index.

Color evaluation for this specimen is precise and technical, described as intense greenish yellow with lively saturation and a medium light tone. Chrysoberyl s refractive index in the range of 1.746 to 1.755 coupled with its relatively low dispersion of approximately 0.014 means that the gem exhibits strong brilliance and scintillation without the overt spectral fire found in higher dispersion materials, and this characteristic allows the greenish yellow hue to read cleanly across different lighting environments. The mixed brilliant cut was deliberately chosen to balance scintillation with color depth, using pavilion angles that retain a concentrated face up color while the well executed crown facet pattern disperses light into small, lively flashes. The intense color intensity quoted is a function of both natural coloration and the cutter s decisions, the result being a vivid presence that remains appealing at ring scale, and the small overall dimensions are consonant with chrysoberyl s specific gravity of approximately 3.73 to 3.75 which yields notable weight relative to size.

Clarity is described as slightly included when evaluated at eye level, a practical assessment for collectors who understand that chrysoberyl often contains small pinpoint crystals or healed fissures that do not compromise structural integrity. Under magnification these inclusions are identifiable and are generally situated away from the table plane and primary light path, which means they have minimal impact on brilliance and do not obstruct the gem s attractive transparency. From a gemological and setting perspective the slightly included grade informs mounting choices, for example a bezel or protective low profile prong setting will guard against knocks while preserving the face up presentation. The gem is natural and untreated, with no heating, diffusion, or oiling reported, a condition that maintains the original crystal chemistry and zonal color distribution. The hardness of chrysoberyl at 8.5 on the Mohs scale further supports daily wearability, making this stone suitable for engagement jewelry or a center accent in a bespoke piece that will be worn frequently.

The provenance from Sri Lanka, historically referenced as Ceylon, is significant both culturally and commercially, as the island has been a primary source for fine chrysoberyl for centuries, and its gem cutting traditions have long emphasized the marriage of material character and lapidary technique. Historically chrysoberyl varieties have been used in South Asian jewelry and talismanic objects for perceived protective and auspicious properties, a heritage that informs the contemporary appeal of a vivid Ceylon chrysoberyl presented with modern cutting precision. For the connoisseur who values documented origin, natural state, and technical execution, this 0.46 carat oval greenish yellow chrysoberyl represents a compact but sophisticated example of the species. The Natural Gemstone Company stands behind the gem s origin and treatment status, and can assist with certification, bespoke mounting recommendations, and advice on metal pairings that best complement the warm yellow green tone, such as white metals to emphasize brilliance or warm yellow gold to harmonize with the hue.
