This transparent 19.75 carat oval purple amethyst presents precise proportions and high quality craftsmanship, dimensions 19.43 by 15.93 by 10.32 mm, faceted in a mixed brilliant cut to optimize both color saturation and light return. The length to width ratio of 1.22 situates the oval within classic design parameters for balanced wearability, while the depth represents a calculated 58.4 percent of the average girdle diameter, a proportion chosen to retain maximum weight without sacrificing optical performance. The pavilion and crown were cut to controlled facet angles to enhance internal reflection, creating a lively interplay between the large table facet and numerous crown facets, producing strong scintillation across the face. Clarity is eye clean when evaluated at normal viewing distance, indicating minimal to no visible inclusions that would interrupt the path of light, and polish is rated excellent, yielding razor sharp facet junctions and high surface luster. Color intensity is intense, exhibiting a deep, saturated purple with uniform distribution and minimal zoning, natural origin Brazil, enhancement none.
The journey of this stone from mine to market reflects deliberate, technically driven decisions at every stage. Sourced from Brazilian alluvial pockets, the rough was selected for homogenous color and structural integrity, then preformed by experienced cutters to respect natural crystal orientation and reduce the risk of cleavage. During faceting, the cutter employed a mixed brilliant pavilion geometry to marry classic brilliance with the broad color canvas an amethyst offers, adjusting crown height and table size to manage the trade off between depth and face up color. Polishing used progressively finer diamond laps to secure an excellent finish, and every facet junction was checked for symmetry under loupe magnification. No heat or chemical treatments were applied, preserving the gem in its natural state. Final quality control at The Natural Gemstone Company included standardized photographic documentation, measurement verification, and independent visual grading for clarity and color intensity. The result is a technically refined, market ready gemstone that carries clear origin, unchanged enhancement status, and the cutting choices that maximize both visual impact and structural soundness, ready for setting in a bespoke piece or acquisition by collectors who value disciplined lapidary execution.
