2.58 Ct. Topaz from Ceylon (Sri Lanka)

This transparent sky blue topaz weighs 2.58 carats and measures 8.97 by 6.99 by 4.81 millimeters, presented in a classic emerald cut that emphasizes clarity and color. The stone exhibits a medium light color intensity, a refined, cool sky blue that reads evenly across the table and through the step facets. Clarity is graded as eye clean, evaluated at normal viewing distance, which means there are no inclusions visible to the unaided eye and the gem presents a clean, open appearance that is ideal for the emerald cut. The polish is excellent, producing crisp facet junctions and strong light return along the steps, and the gem is transparent and uniformly saturated without color zoning. This topaz has been enhanced by irradiation, a standard and stable treatment for producing attractive blue tones in topaz, and the treatment is fully disclosed. The combination of its weight, the precise emerald cut, and the clean transparency delivers a substantial face up presence for a 2.58 carat stone, suitable for a prominent solitaire or an elegant three stone setting.

From a gemological and buyer perspective, several grading factors make this topaz particularly attractive to an educated purchaser, beginning with the emerald cut itself. Step cuts like the emerald emphasize internal clarity and the purity of color, producing a hall of mirrors effect that offers sophisticated flashes of light rather than scintillation, so an eye clean material and excellent polish create the ideal optical performance. The medium light color intensity sits within the most desirable range for sky blue topaz, providing a pleasing, wearable blue that complements both white and warm metal settings. Irradiation is the industry standard enhancement for blue topaz, it is an accepted and permanent treatment when performed and followed by proper post treatment protocols, and it is important for buyers to receive full disclosure, which we provide. The stone’s dimensions and proportion produce a strong table to depth ratio, which enhances face up size while maintaining good depth for secure setting and durability. Topaz rates an 8 on the Mohs hardness scale, offering substantial resistance to everyday wear, though as with all gems care should be taken to avoid harsh knocks and extreme thermal shock.

The origin of this topaz in Ceylon, modern day Sri Lanka, adds a meaningful layer of provenance and value. Sri Lanka has a long, documented history of producing high quality gem material, and its alluvial and pegmatitic deposits are known to yield stones with fine clarity and attractive color that appeal to connoisseurs and collectors. Provenance from Ceylon signals not only geological quality but also a traceable supply chain and often artisanal cutting traditions that are respected in the market, which can command a premium compared with anonymous sources. For the discerning buyer, provenance provides reassurance about sourcing practices and long term desirability, especially when combined with third party verification or detailed company documentation. At The Natural Gemstone Company we prioritize transparent sourcing and strict quality control, and we stand behind the gem with full disclosure of treatments and origin. For care we recommend cleaning with warm soapy water and a soft brush, avoiding prolonged exposure to high heat or harsh chemical cleaners, and considering an independent gemological report if you intend to insure or resell the stone. This sky blue emerald cut topaz from Ceylon is a refined, technically well presented gem that offers a compelling blend of eye clean clarity, elegant cut, stable enhancement, provenance, and everyday wearability, and it represents a strong choice for both collectors and fine jewelry clients seeking a beautifully balanced blue topaz.
