2.31 Ct. Topaz from Ceylon (Sri Lanka)

This Swiss blue topaz weighs 2.31 carats and presents a perfectly balanced round shape, with exact dimensions of 7.85 x 7.93 x 5.26 mm. Cut to a mixed brilliant style, this stone combines the brilliance of a modern pavilion with the fire of graduated crown facets, yielding lively light return and pleasing scintillation. Clarity is graded as very very slightly included when evaluated at eye level, a level of purity that translates into clean appearance and minimal visible interruptions to light performance. Color intensity is medium intense, offering a vivid yet wearable blue that reads as classic Swiss blue under a variety of lighting conditions. Polish is excellent, so facet junctions are smooth and the surface presents a mirror finish that enhances the stone face up. This topaz has been enhanced by irradiation, a stable and widely accepted treatment for producing the desirable Swiss blue hue. The gem originates from Ceylon Sri Lanka, a locality known for producing topaz with fine crystal form and attractive color when treated, and provenance from that region adds appeal to collectors and connoisseurs who value traceable origins. As a seller experienced in gem grading I can explain that the combination of weight, cut, clarity, and polish in this stone positions it as a premium example of irradiated Swiss blue topaz, while the documented Sri Lankan origin and the VVS level clarity support confidence in quality for an educated buyer.

For an engagement ring this 2.31 carat Swiss blue topaz makes an exceptional center stone, offering a unique and modern alternative to more traditional choices while retaining durability for daily wear with a hardness suitable for most settings. The medium intense blue provides an elegant contrast when paired with white metals or warm yellow gold, and for clients seeking a soft companion stone we offer designs featuring White Opal accents, where the light body tone of White Opal introduces a gentle iridescence without overpowering the blue center. Practical considerations include opting for a secure prong or bezel setting to protect the girdle and choosing a metal and profile that minimize edge impacts, and we at The Natural Gemstone Company are available to advise on mounting options that preserve both beauty and longevity. This topaz represents a thoughtful choice for an engagement piece, combining eye catching color, excellent polish and high clarity, all supported by transparent treatment and origin disclosure for buyers who demand both aesthetic appeal and responsible sourcing.
