21.39 Ct. Imperial Topaz from Brazil

From the moment this reddish orange imperial topaz was first liberated from hard rock in Brazil, its journey was governed by geological time and careful human decision making. Formed in late stage granitic pegmatites, the rough material displayed zoned chromophores that produced the rare brown orange to reddish orange palette now visible in the polished stone. Field sorting in situ prioritized pieces with dense, even saturation and minimal fracturing, and the selected crystal was documented as Other certified brown orange before being transported to our cutting studio. At The Natural Gemstone Company we recorded the rough dimensions, noted the orientation of color zoning and internal growth features, and mapped potential facet arrangements. That mapping process determined that an oval outline would best balance retention of weight with the delivery of optimum color display, so the cutter planned an economy conscious but quality driven approach that would preserve a generous 21.39 carat yield in the finished gem.

The cutting phase translated geological information into optical performance through disciplined facet engineering. The stone was faceted in a mixed brilliant design, featuring a brilliant crown with well proportioned star and kite facets, and a modified pavilion that blends pavilion mains with refined step like elements to control light return and color saturation. The finished proportions are 19.93 x 14.77 x 9.66 mm, with a table size chosen to enhance the face up reddish orange tone while maintaining contrast through calibrated pavilion depths. The clarity was assessed as very slightly included evaluated at eye level, and inclusions are positioned and oriented so that they do not interrupt the overall window of color when the stone is set. The gem presents intense color intensity through a combination of intrinsic chromophore concentration and the cutting strategy that promotes internal reflections of warm tones. Heat treated enhancement was applied to stabilize and intensify the reddish orange hue, a common and accepted treatment for topaz that yields consistent color throughout the body of the stone. Surface finish received an excellent polish, with crisp facet junctions and smooth girdle execution, yielding superior brilliance and a lively scintillation pattern across the crown.

When this imperial topaz reached the marketplace it carried both technical provenance and practical versatility. Buyers who value material science will appreciate that topaz has a refractive index range and hardness that make it robust for everyday wear, while the gemologist level documentation provided by The Natural Gemstone Company traces the stone from mine to master cutter to finished inventory. The 21.39 carat oval is well suited to single stone pendants and statement rings where the elongated outline emphasizes the warm reddish orange spectrum, and the mixed brilliant cut maintains light performance in settings that allow for moderate light access through the pavilion. For bespoke jewelry the gem pairs exceptionally well with warm yellow gold to amplify the brown orange facets, and with rose gold when a subtler, vintage inspired warmth is preferred. We recommend secure four or six prong settings or a bezel with a delicate open under gallery to permit light ingress and to protect the girdle. Routine care consists of gentle ultrasonic cleaning when no fractures are present, and periodic professional inspection to confirm setting integrity and surface condition.

This gem represents a balance of natural rarity, measured enhancement, and precision craftsmanship, attributes that are central to The Natural Gemstone Company approach to sourcing and finishing fine material. The documentation accompanying the stone includes origin notes, treatment disclosure, dimensions and clarity assessment, enabling confident valuation and grading by independent appraisers. For connoisseurs of color and technical quality, this imperial topaz stands as a demonstrable example of how informed cutting choices, careful treatment protocols, and detailed grading yield a jewel ready for both display and durable wear, and our team is available to discuss setting options, custom mounting, and shipping logistics for buyers worldwide.
