4.27 Ct. Precious Topaz from Brazil

This 4.27 carat oval precious topaz from Brazil measures 10.64 x 7.95 x 6.00 mm, presenting a clean, transparent body with an orangish yellow hue of medium intense color intensity. The gem is fashioned in a mixed brilliant cut, with a brilliant faceted crown paired with more restrained step influenced facets on the pavilion, a configuration that maximizes scintillation while preserving color saturation along the length of the oval outline. The mixed brilliant geometry enhances light return across the table and crown facets, producing crisp pinpoint scintillation and broad flash patterning, while the oval proportions minimize the perceptible bow tie effect typical of elongated shapes. Clarity is graded as very slightly included, evaluated at eye level, indicating minimal natural inclusions that do not impede transparency or compromise optical performance. The piece exhibits an excellent polish, delivering a bright vitreous to subtly subadamantine surface luster that sharpens facet junctions and improves overall light return. There is no enhancement, which guarantees natural color and structural integrity, and the stone’s Brazilian origin attests to its provenance and typical topaz crystal quality.

In comparison to more common gemstones the brilliance profile of this topaz is distinct and technically advantageous for collectors and connoisseurs who value crisp facet contrast and strong windowed color. Versus diamond this topaz has a lower optical dispersion and thus less fire, but its mixed brilliant arrangement exploits topaz’s refractive characteristics to yield highly defined scintillation and clean reflections that are more geometric and mirror like than the dispersed multicolored flashes seen in diamond. Versus corundum varieties such as sapphire or ruby which rely on deep color saturation and a more subdued luster, this topaz offers a brighter, more reflective appearance that emphasizes sparkle and light play without heavy color masking. Versus quartz varieties such as citrine the topaz displays superior facet brilliance and durability under repeated polishing, producing sharper light return and greater surface brilliance. The absence of treatment preserves the stone’s natural optical equilibrium, and the excellent polish accentuates the mixed brilliant architecture, resulting in a gem that stands out for its balance of vibrant orangish yellow color, precise cutting, and lively, crystalline brilliance.
