3.24 Ct. Topaz from Ceylon (Sri Lanka)

This Swiss blue topaz is a transparent, round mixed brilliant cut weighing 3.24 carats with precise dimensions of 9.04 by 9.02 by 5.98 millimeters. The cutting style combines a traditional round outline with pavilion and crown faceting optimized to maximize return of light and color saturation, and the gem has been finished to an excellent polish. Clarity has been evaluated at eye level as very very slightly included, indicating inclusions are minute and do not impede visual performance under normal viewing. Color intensity is classified as intense, presenting the vivid, saturated blue commonly described as Swiss blue, and the stone has been enhanced by controlled irradiation, a standard and widely accepted treatment that produces stable color when properly performed and disclosed. The topaz originates from Ceylon, Sri Lanka, and is presented with full disclosure of origin and enhancement by The Natural Gemstone Company.

In practical and aesthetic terms this topaz offers strong appeal for precision set jewelry and for collectors seeking a well-proportioned, eye-clean specimen. The mixed brilliant faceting yields lively scintillation and a broad distribution of blue tones across the table and crown facets, while the nearly round dimensions make it straightforward to center in a variety of settings. As with all natural topaz, hardness is approximately 8 on the Mohs scale, providing good resistance to daily wear, though the mineral’s distinct cleavage plane requires careful handling and professional setting to minimize risk of cleavage-related damage during manufacture or impact. The irradiation used to produce the Swiss blue color is a permanent enhancement under normal wear conditions, and when combined with the excellent polish and precise cutting it produces consistent performance in light return and color stability.

Compared with lab-grown blue gemstones, a natural Swiss blue topaz from Sri Lanka offers attributes that matter to many buyers and collectors. Natural stones bring provenance, a geologic history and growth fingerprint expressed by characteristic inclusions, zoning, and microscopic features that cannot be authentically replicated in the same way in a laboratory-grown material. These natural growth features serve as identifying markers for origin and contribute to long-term rarity and market considerations, factors that can influence resale and collectible value. Lab-grown gems typically provide very uniform color and high clarity at a lower price point and with excellent repeatability, which is desirable for some applications, but they lack the unique origin narrative and naturally occurring formation characteristics that define a natural stone. For consumers prioritizing documented origin, natural rarity, and the subtle individuality of formation, a transparent, eye-clean Swiss blue topaz like this one from Ceylon represents a distinct advantage. The Natural Gemstone Company maintains transparent disclosure of treatments and origin and can provide photographic documentation and examination reports upon request to support provenance and valuation.
