21.42 Ct. Topaz from Ceylon (Sri Lanka)

This specimen is a beautiful transparent 21.42 carat emerald cut blue topaz, with precise dimensions of 18.24 by 13.33 by 8.65 mm, offered by The Natural Gemstone Company. The classical emerald cut emphasizes step facets and broad tables, creating even, architectural flashes of light that suit either a bold solitaire or an elegant pendant. Clarity is graded as very very slightly included, evaluated at eye level, which means that to the unaided eye the stone reads as clean and bright, while minute natural features confirmed by gemological inspection attest to its natural origin. Color intensity is medium light, a refined aqua blue that remains versatile across different settings and metals. The finish is described as excellent polish, which enhances surface luster and maximizes the gem s ability to return light. The stone has undergone irradiation to achieve its blue hue, a common and stable enhancement for topaz that is fully disclosed here, and one that does not compromise structural integrity when standard care is observed. The topaz is from Ceylon, Sri Lanka, a historical and respected source, and the combination of weight, cut, and very good clarity makes this piece noteworthy for both connoisseurs and designers seeking a statement yet wearable gemstone.

Beyond its optical and gemological attributes, this blue topaz is presented with ethical sourcing and traceability in mind, in keeping with The Natural Gemstone Company s responsible purchasing policy. We work directly with ethical partners and reputable suppliers in Ceylon, Sri Lanka, who adhere to fair labor practices and environmental safeguards, and we prioritize transparent supply chains that allow for origin verification and respectful treatment of mining communities. For the conscious consumer, this gem combines aesthetic and scientific credibility, the disclosed irradiation treatment offering confidence rather than ambiguity, and the clear provenance aligning with values of responsible buying. In practical terms, the gem is ideal for a collector or a client seeking a central stone for a high quality ring, pendant, or bespoke commission, because the emerald cut and substantial 21.42 carat weight deliver presence without unnecessary complexity. If you require certification, additional imaging, or assistance designing a setting that honors both the material beauty and ethical story of this stone, The Natural Gemstone Company is available to provide documentation and consultation.
