0.27 Ct. Emerald from Afghanistan

This 0.27 carat round green emerald, supplied by The Natural Emerald Company, demonstrates how precision cutting can transform the inherent optical properties of beryl into concentrated brilliance, clarity and color saturation. The gem measures 4.81 by 4.76 by 2.55 mm, giving a depth ratio of approximately 53.3 percent, a proportion that balances internal reflection and light return for beryl with a refractive index in the range of 1.577 to 1.583. The mixed brilliant cut combines a brilliant style crown with a modified pavilion configuration, creating a network of star and kite facets on the crown and elongated pavilion facets that redirect light through complementary angles. Facet junctions are uniformly aligned to promote symmetrical light paths, so incoming light encounters sequential reflections that enhance scintillation and preserve color uniformity rather than dispersing it into excessive leakage. The excellent polish contributes to clean facet planes that minimize scattering losses at the surface, increasing apparent transparency and allowing the vivid green hue to broadcast with maximum saturation.

Color and clarity are treated with the same technical rigor, the piece showing vivid color intensity coupled with transparency that allows saturation to be read through the table without significant obstruction. Clarity is very slightly included evaluated at eye level, with inclusions minimal and positioned so as not to interrupt primary light return channels. Standard enhancement has been applied, consistent with trade practice for emeralds, improving stability of appearance while retaining natural character. The cutter calibrated pavilion angles and table proportions to the specific birefringence of emerald, reducing windowing and enhancing face up brilliance, so the gem presents a lively balance of flash and deep green body color in both daylight and artificial lighting. Origin from Afghanistan is noted for producing clean, vividly colored stones, and this example reflects the region's material quality and the meticulous craftsmanship invested in preforming and final faceting. For buyers who value technical execution and optical performance, this emerald is an instructive example of how expert cutting and finishing convert geological color and clarity into measurable visual performance, a standard upheld in every offering from The Natural Emerald Company.
