1.62 Ct. Chrysoberyl from Ceylon (Sri Lanka)

One transparent pear shape chrysoberyl weighing 1.62 carat, dimensions 9.92 x 6.46 x 4.28 mm, mixed brilliant cut, greenish yellow hue with medium intense color intensity, clarity grade very very slightly included as evaluated at eye level, excellent polish, no enhancement, origin Ceylon Sri Lanka. This example from The Natural Gemstone Company combines precise cutting and high quality rough to present an exceptionally clear and lively stone. The mixed brilliant arrangement of facets balances table and pavilion proportions to maximize internal reflection, while careful polishing preserves crisp facet junctions and clean contrast. The resulting appearance is a clean, saturated greenish yellow presence, with abundant return of light and controlled dispersion when subjected to both steady and moving light.

The distinctive sparkle of chrysoberyl is a direct outcome of its crystal and optical properties, combined with expert cutting. Chrysoberyl crystallizes in an orthorhombic lattice, a structurally anisotropic framework that influences the way light is refracted and split within the material. Its relatively high refractive index means that a larger proportion of incident light is bent and reflected back through the crown, creating strong brilliance. At the same time the material displays modest dispersion, which produces measured flashes of spectral color without overwhelming the body color. Biaxial optical behavior can contribute subtle internal light separation that, when harnessed by a mixed brilliant cut, enhances scintillation and the perceived depth of the gem. The cutter of this stone optimized facet geometry to take advantage of those properties, positioning crown and pavilion facets so light traverses differing path lengths and encounters multiple internal reflections before exiting, a sequence that increases dynamic sparkle and lively contrast at short viewing distances and in motion.

Physical durability and finish further reinforce the visual effect, and support long term performance in jewelry. Chrysoberyl has a high hardness which allows facets to be cut sharply and to retain polish under normal wear conditions, preserving the crisp interplay of light over time. The medium intense greenish yellow color of this piece is neither washed out nor overly dark, permitting both bright flashes from the crown and deeper contrast from the pavilion, a balance that intensifies perceived brilliance. Clarity described as very very slightly included at eye level indicates inclusions do not significantly interrupt light return, so scintillation remains clean and uninterrupted. In practical terms this means the gem projects a lively, three dimensional look on the finger or in a pendant, with a consistent pattern of bright facet flashes and fine, controlled fire. For clients seeking a colored gem with both durability and optical liveliness, this chrysoberyl from The Natural Gemstone Company demonstrates how material, cut, and finish combine to produce a sparkle that is distinctive among colored gems, and in many respects unmatched.
