15.69 Ct. Yellowish Green Prasiolite from Madagascar

This specimen is a transparent yellowish green prasiolite, emerald cut, weighing 15.69 carat, with dimensions 17.28 by 12.30 by 9.81 mm. The cut is an elongated emerald shape that emphasizes the stone’s table and step facets, producing broad flashes of color and a refined geometric presence. Clarity is graded as very very slightly included, evaluated at eye level, which ensures a clean appearance to the unaided eye while preserving natural internal characteristics. Color displays an intense color intensity, a vivid and even yellowish green tone that responds well to both natural and artificial lighting. The polish is excellent, reflecting precise facet junctions and a smooth pavilion finish, and the material has been heat treated to stabilize and enhance its color. Origin is Madagascar, a source known for producing high quality prasiolite material with distinct hue and character.

Compared to lab grown gemstones, this natural prasiolite offers attributes that appeal to collectors and connoisseurs who prioritize provenance, natural formation, and unique internal features. Lab grown stones can provide highly consistent color and clarity, however they lack the geological history and trace element signatures that are present in natural material, attributes that are often important for long term value and differentiation. Natural prasiolite from Madagascar carries a rarity and one of a kind aspect, with subtle inclusions and growth patterns that attest to its origin and formation, and these features are visible under magnification and appreciated by gemological study. Natural stones also allow for verifiable origin documentation and the tactile assurance of a material formed over geological time. For clients seeking a refined, sizeable centerpiece for bespoke jewelry, this 15.69 carat emerald cut prasiolite presents a balanced combination of weight, color saturation, and clarity, ideal for a prominent ring or pendant setting. The Natural Gemstone Company offers this prasiolite with detailed provenance and condition information, and can provide further assistance on setting considerations to maximize the stone’s step cut brilliance and overall presentation.
