5.82 Ct. Red Fire Opal from Mexico

This Fire Opal is a transparent, oval shape gemstone weighing 5.82 carat, with precise dimensions of 15.87 x 12.02 x 7.27 mm. The stone is fashioned with a mixed brilliant cut that combines a faceted crown optimized for light dispersion with a proportioned pavilion that supports strong return and depth of field. Faceting follows a classical mixed brilliant schema, where triangular and kite shaped crown facets meet step influenced pavilion facets to preserve table size while enhancing body color. Clarity has been graded eye clean at normal viewing distance, which allows the vivid red hue to read uniformly across the table without visual interruptions. Color intensity is vivid, displaying saturated red tones characteristic of high quality Mexican fire opal, and the surface displays an excellent polish, indicating meticulous lapidary finishing and careful polishing sequences. There is no enhancement, the transparency is natural, and provenance from Mexico is provided, assuring collectors and connoisseurs of its origin and untreated status. The Natural Gemstone Company offers this gem with full technical disclosure and imaging to support its quality assessment.

The 5.82 carat weight is central to this stones value profile, because carat weight in colored gemstones compounds rarity and visual impact in a non linear fashion, especially for transparent fire opal material. At this weight and at these dimensions, the stone presents a substantial face up area that amplifies the vivid red saturation, and the larger table area allows the mixed brilliant faceting to produce consistent color delivery without appearing windowed or overly dark. From a market and rarity perspective, transparent Mexican fire opal material of this weight and of eye clean clarity is uncommon, which increases its desirability for high end settings and investment grade collections. The cutter balanced crown height and pavilion depth to maximize brilliance while preserving color, a technical choice that enhances light return and reduces extinction in the center. For setting considerations, the gem will perform well in open faced designs that allow transmission light, and it can also anchor statement pieces where its weight provides both physical presence and financial substance. The Natural Gemstone Company stands behind the gem with technical documentation and can provide additional photographs, facet schematics, and advice on mounting to preserve the stones luster and value.
