17.48 Ct. Topaz from Ceylon (Sri Lanka)

A jewel of unmistakable presence, this transparent 17.48 carat heart shape blue topaz measures 16.00 x 16.19 x 10.14 mm, a size that reads as both statement and heirloom. Cut in a refined mixed brilliant fashion, its proportions and symmetry have been calibrated to deliver maximum return of light, producing a scintillation and brilliance that arrest the eye. The vivid color intensity is an oceanic blue that registers as both saturated and pure, a color rendered more alive by an excellent polish that allows each facet to sing. Clarity grade of very very slightly included, evaluated at eye level, means the stone presents as visually pristine to the wearer, with inclusions so discreet they do nothing to diminish the gem’s luminous character. This topaz has undergone enhancement by irradiation, a common, stable treatment that deepens its tone while preserving the natural crystalline integrity. Origin Ceylon Sri Lanka anchors this gem in a legacy of exceptional rough that gem connoisseurs associate with fine color and clarity, and at The Natural Gemstone Company we present it as a rare find for the collector who values provenance, presence, and polish.

What separates this heart from ordinary blue topaz is its internal architecture, the precise interplay between facet geometry and optical physics. The mixed brilliant cut marries the reflective sparkle of brilliant facets on the crown with the controlled light return of step facets in the pavilion, creating a dynamic tapestry of pinfire scintillation and larger, more dramatic flashes. The pavilion depth, cut angles, and crown faceting have been optimized for topaz’s optical character, encouraging internal reflection that cycles light back to the eye rather than allowing it to leak away, so each movement of the hand releases a choreography of brightness. The heart silhouette amplifies this effect, its lobes and cleft acting as lenses that refract and concentrate color into lively areas of contrast, while excellent polish ensures there is no barrier between the gem and the light. In hand or set as a centerpiece, this blue topaz speaks of cultivated taste, a confident aesthetic, and the quiet luxury of having sourced an exceptional stone through The Natural Gemstone Company, an investment in beauty that transcends trends and endures as a personal emblem of refinement.
