37.20 Ct. Orange Fire Opal (Flame Opal) from Mexico

This Fire Opal, Flame Opal, offered by The Natural Gemstone Company is a rare, transparent 37.20 carat specimen of radiant shape precision, with measured dimensions of 22.83 x 22.83 x 14.98 mm. The stone is faceted in a classic radiant cut that marries stepped pavilion geometry with a brilliant facet crown, producing a controlled balance of scintillation and broad luminous surfaces. The facet architecture features trimmed corners and a well proportioned table that maximizes internal reflections, while the pavilion faceting has been executed to optimize light return and to present the opal s intense orange hue with even saturation. Origin is Mexico, enhancement is none, and the polish is graded excellent, indicating a fine lapidary finish with crisp facet junctions and minimal surface disturbance.

From a clarity and color grading standpoint this piece is of exceptional interest to discerning collectors. Clarity is graded very slightly included, evaluated at eye level, with small natural internal characteristics that do not materially impair transparency or light performance, and that in some orientations contribute subtle internal texture typical of natural Mexican fire opal. Color intensity is described as intense, with a vibrant, pure orange field that displays minimal color zoning under standard viewing. The combination of substantial carat weight, transparent body, untreated status, and meticulous cutting yields pronounced internal glow and strong face up presence when set or displayed. Craftsmanship techniques evident in this cut include precise facet symmetry, controlled pavilion depth for optimized brilliance, and a consistent girdle outline that allows for secure mounting with minimal risk to weight retention. For high end gemstone collections this radiant fire opal offers both technical refinement and collector appeal, serving as an exemplary representation of Mexican flame opal material that performs beautifully under loupe and to the eye, and that stands as an investment quality addition to a curated collection.
