5.82 Ct. Red Fire Opal (Flame Opal) from Mexico

This exceptional Fire Opal, Flame Opal, presents as a transparent, faceted oval weighing 5.82 carats, with measured dimensions of 15.87 by 12.02 by 7.27 mm, originating from Mexico, and offered by The Natural Gemstone Company. The weight of 5.82 carats is a defining attribute that materially affects both rarity and market value, because faceted, transparent fire opals of this size are uncommon in the trade, and per carat pricing typically increases as size steps into higher weight brackets due to limited rough, yield loss during cutting, and the challenge of retaining vivid saturation in larger faces. This specimen is eye clean when evaluated at normal viewing distance, which removes the typical inclusion discounts and allows the full color intensity to command premium pricing. There is no enhancement, and the excellent polish combined with transparency ensures maximal light transmission, making the weight not only a quantitative measure but a qualitative advantage, since larger, clean stones display color depth and saturation more convincingly than smaller equivalents.

Technically, the gem is cut in an oval outline with a mixed brilliant facet arrangement, selected to optimize the unique optical properties of a fire opal. The mixed brilliant design uses a faceted crown with modified brilliant facets over a pavilion that balances triangular and kite facets, generating focused return of light through the table while preserving color saturation across the body of the stone. Faceting angles have been controlled to minimize light leakage and to favor warm red to orange hue concentration in the girdle to table axis, which is particularly important in fiery opals where color intensity is the primary value driver. The excellent polish accentuates facet junction precision, contributing to crisp facet contrast and stable reflections under varied lighting. For connoisseurs and technical buyers, the combination of a substantial 5.82 carat weight, eye clean clarity, vivid color intensity, lack of enhancements, and expert mixed brilliant faceting yields a rare investment grade fire opal that performs well in bespoke settings, particularly as a center stone in rings or pendants where the mass and facet architecture can be fully appreciated.
