32.44 Ct. Blue Topaz from Brazil

One transparent blue topaz, 32.44 carats, round shape, dimensions 16.38 by 16.35 by 13.90 millimeters, fancy cut, clarity graded eye clean when evaluated at eye level, light color intensity, excellent polish, enhancement by irradiation, origin Brazil, presented as a refined inclusion for a high end gemstone collection. The gem displays consistent tone across the table and crown, and its transparency allows for unhindered observation of optical characteristics under standard viewing conditions. The reported weight and millimeter measurements place this example among larger single stones of its species, which contributes to its presence when mounted or exhibited, and supports its categorization for collectors who prioritize size with maintained optical quality.

The cutting style is a deliberate departure from a classical brilliant profile, performed in a fancy cut that emphasizes a domed, multi faceted crown and a robust pavilion, resulting in a pronounced three dimensional form that interacts with light in a distinct manner. The recorded depth relative to the mean diameter is approximately eighty five percent, which is substantial compared with typical proportions, and this greater depth yields a tempered combination of internal flash and soft color diffusion rather than the high contrast scintillation associated with shallow brilliant cuts. The excellent polish supports clean facet junctions and minimizes surface diffusion of light, permitting the stone to present a lucid, vitreous luster across its facets. The clarity assessment of eye clean indicates absence of inclusions visible without magnification, which in combination with the gem s transparency promotes visual uniformity and allows faceting nuances to be readily evaluated by practitioners and connoisseurs.

The stone has undergone irradiation to induce its blue hue, a stable and commonly applied treatment within the trade, and this enhancement is disclosed to provide full transparency regarding condition and origin. While irradiated color in topaz is generally durable for normal wear, prolonged exposure to elevated temperatures in the absence of professional guidance can alter tonality, and standard care practices are recommended, such as avoiding harsh chemicals and aggressive thermal or ultrasonic cleaning without prior consultation. Provenance from Brazil is documented, aligning with established supply regions for commercial and collector grade topaz. Offered through The Natural Gemstone Company, this specimen is characterized for collectors and jewelers seeking a substantial, transparent blue topaz that combines uncommon dimensions with a distinctive fancy cut, clear visual presentation, and conventional, disclosed treatment.
