128.90 Ct. Blue Topaz from Ceylon (Sri Lanka)

One beautiful transparent 128.90 carat oval shape blue topaz presents an immediate impression of scale and refinement, with dimensions of 33.70 x 23.44 x 20.00 mm that speak to a statement piece suitable for a variety of designs. The stone is faceted in a mixed brilliant cut, combining the pavilion and crown geometry associated with brilliant faceting and the elongated elegance of an oval outline, a combination that produces a balanced interplay of scintillation and broad flash. With a clarity grade of very very slightly included, evaluated at eye level, the gem reads as effectively eye clean while retaining natural character when observed under magnification. The cutting proportions emphasize symmetry and table size appropriate to its weight, and the excellent polish ensures clean facet junctions and a smooth surface that contributes directly to the stone's visual performance and tactile quality.

The blue topaz exhibits medium color intensity, a depth that allows for a satisfying presence without appearing heavily saturated, and the transparent body allows light to travel with minimal obstruction. The mixed brilliant cut is optimized to enhance light return and to display both lively sparkle and uniform color distribution across the oval plane. The gem has undergone irradiation as an enhancement, a well established and stable treatment for producing the classic blue tones associated with fine topaz, and its appearance benefits from a predictable and enduring color result under normal wear conditions. Origin is recorded as Ceylon, Sri Lanka, a source noted for producing topaz specimens with clean crystal habit and favorable clarity, this provenance contributing to the gem's documentation and collectible interest. The overall finish and polish quality are excellent, with crisp facet edges and a surface condition that maximizes the stone's optical potential.

The size and proportions of this blue topaz afford considerable versatility, allowing it to be set with equal success in both casual and formal contexts, from understated everyday pieces to more elaborate evening jewelry. In a casual setting the gem lends itself to pendant configurations and drop earrings that emphasize movement and approachable scale, while in formal applications the same stone functions as a striking center in a solitaire ring or a halo composition, where surrounding accent stones can be used to modify perceived color and increase visual contrast. Designers will find the oval silhouette amenable to both east west and traditional north south orientations, and the mixed brilliant faceting adapts well to settings that showcase both table facet brilliance and perimeter flashes, such as tension settings, bezel mounts with open backs, and classic prong assemblies. For practical considerations and longevity in everyday wear, secure prong settings or a protective bezel are advisable given the gem size, and a lower profile mounting will reduce the risk of impact while maintaining presence.

Care and handling recommendations are straightforward and aligned with the material properties of topaz and the known behavior of irradiation treatment, avoid exposure to extreme heat and prolonged contact with strong acids or abrasive cleaners, clean with warm water, mild detergent, and a soft brush, and dry with a lint free cloth. When not being worn, store the stone separately from harder gemstones to prevent surface abrasion, and consider an insured appraisal if the piece is incorporated into high value jewelry. Documentation provided by The Natural Gemstone Company accompanies this gem, detailing its carat weight, dimensions, cut style, clarity assessment, color intensity, enhancement status, and origin, providing clarity for makers, appraisers, and collectors. The combination of noteworthy size, precise cutting, stable enhancement, and Ceylon provenance makes this blue topaz an adaptable and durable option for refined jewelry designs across a spectrum of occasions.
