4.13 Ct. Chrysoberyl from Ceylon (Sri Lanka)

One beautiful transparent 4.13 carat emerald cut greenish brown chrysoberyl is presented by The Natural Gemstone Company. The stone measures 11.75 x 8.46 x 4.62 mm, and its proportions have been optimized for the step cut to emphasize color and clarity. Clarity is graded eye clean at standard viewing distance, and color intensity is described as intense, yielding a rich, saturated greenish brown that reads consistently across the table and crown. The polish is excellent, producing crisp facet junctions and smooth facet planes that contribute to surface brilliance. There has been no enhancement to this gem, and its origin is Ceylon Sri Lanka, a locality historically recognized for producing well colored chrysoberyl with good clarity and cut quality. The combination of weight, dimensions, polish, and natural color results in a gem that presents with immediate presence in jewelry settings without additional treatment.

When compared with more commonly encountered gemstones, this chrysoberyl stands out for its balance of refractive response, durability, and unenhanced color saturation. Chrysoberyl typically exhibits a refractive index around 1.74 to 1.76, which is higher than that of quartz and topaz, and slightly below that of corundum. This refractive profile produces a lively, bright appearance that translates particularly well in a well executed emerald cut, where clean light return and defined step flashes emphasize internal clarity and color rather than dispersion or flashy fire. Unlike emeralds, which frequently display significant inclusions that mute brilliance, this eye clean chrysoberyl offers unobstructed light transmission. Against sapphire and diamond, chrysoberyl will show less fire than diamond and a slightly lower refractive intensity than corundum, yet it benefits from exceptional surface luster and a resistive hardness around 8.5 that preserves lustre and polish in daily wear. The unenhanced, intense greenish brown hue, coupled with excellent polish and eye clean clarity, gives this specimen a distinct, refined presence that is at once durable and visually compelling. The Natural Gemstone Company offers this gem for clients seeking a natural, high quality chrysoberyl that balances brilliance, color, and practicality.
