37.20 Ct. Orange Fire Opal from Mexico

One transparent Fire Opal weighing 37.20 carat, presented in a square radiant shape with overall dimensions 22.83 by 22.83 by 14.98 millimeters, offers a rare combination of size and optical purity. The cutting style is a classic radiant cut, employing a mixed faceting scheme that blends brilliant facets on the crown with modified pavilion facets, and carefully trimmed corners to reduce chipping and allow for secure mounting in high end settings. The stone displays an intense orange bodycolor that is characteristic of top grade Mexican fire opal, and the bodycolor is delivered with remarkable uniformity across the table and faceted planes. Clarity is graded as very slightly included, evaluated at eye level, indicating only minor internal features that do not compromise transparency or light transmission. The depth of 14.98 millimeters yields an approximate depth ratio of 65.6 percent relative to the table dimensions, a proportion that contributes to strong light return and saturated color intensity. The polish is excellent, with clean facet junctions and mirror facets that maximize surface reflectivity, and there has been no enhancement applied to this natural specimen.

From a craftsmanship perspective this piece exemplifies the precision that experienced cutters apply to transparent opal material to optimize both color saturation and structural integrity. The mixed facet architecture is executed to create a lively interaction between crown angles and pavilion slopes, producing even color dispersion and minimizing windowing in the center of the table. Girdle thickness has been maintained for secure setting without adding unnecessary weight, and the trimmed corners inherent to the radiant silhouette reduce vulnerability at pavilion intersections. Origin attribution to Mexico is significant for collectors, as Mexican fire opal is renowned for its pure bodycolor and transparency rather than reliance on play of color. Offered by The Natural Gemstone Company, this 37.20 carat radiant Fire Opal is an exceptional centerpiece for a high end gemstone collection, ideal as a museum quality specimen or as the focal stone in a bespoke jewelry commission, where its scale, intense color, and exceptional cutting will command attention and retain long term desirability.
