This listing describes a single, transparent Swiss blue topaz, 2.54 carats, round shape, with precise dimensions of 8.13 by 8.07 by 5.51 millimeters. The stone is fashioned in a mixed brilliant cut, combining a faceting scheme that balances table size and pavilion angles to enhance both brilliance and scintillation. Clarity has been assessed as very slightly included at eye level, indicating that the internal characteristics do not materially affect visual performance to the unaided eye. Color is classified as medium intensity Swiss blue, providing a clear and vivid hue without appearing overly dark, and the surface finish is graded excellent for polish, contributing to crisp facet junctions and strong light return. The color enhancement method applied to this material is irradiation, a standard and stable treatment for blue topaz, and the rough material is reported to originate from Brazil. The Natural Gemstone Company presents this gem with full disclosure of these technical attributes, as recorded by our in house gemological review.
The combination of weight and dimensions positions this topaz as a strong candidate for a statement piece, particularly in modern jewelry designs that favor a single, prominent center stone. At 2.54 carats and approximately 8.1 millimeters in diameter, the round silhouette occupies a visual footprint that reads larger than its numerical weight at first glance, due to the optimal diameter to depth proportion of this specimen. The mixed brilliant faceting further maximizes surface area reflections, producing lively scintillation across the crown that draws attention without relying on exaggerated saturation. Because the clarity is very slightly included at eye level, the gem projects as clean and transparent at normal viewing distances, which is a critical attribute for statement jewelry where the stone itself is the focal element. The gem maintains consistent tone across the table and crown facets, supporting a uniform appearance whether set in a solitaire ring, a pendant designed to hang freely, or as a prominent center in a cocktail ring.
Optical performance has been carefully considered in the cutting and finishing of this material, and the mixed brilliant cut is executed to preserve weight while optimizing light return. The crown faceting pattern produces a mix of broad flashes and smaller pinpoint scintillation, which reads as dynamic movement under ambient light, while the pavilion arrangement complements this by channeling light back through the crown for perceived brightness. Excellent polish contributes to mirror like facet surfaces and sharp facet junctions, both important to achieve clean reflections and to minimize light leakage. In practical terms, these attributes make the gem suitable for settings that allow open sight lines to the crown, such as prong or semi bezel mounts, and for designs that emphasize contrast between the blue topaz and companion metals or stones. Topaz has a hardness that makes it suitable for most types of daily wear when properly set, and when combined with an appropriate protective setting the gem will function well as a centerpiece in both contemporary and classic designs.
The provenance from Brazil and the disclosed enhancement through irradiation are relevant to both aesthetic and long term considerations, and The Natural Gemstone Company provides this information to support informed selection. Irradiation followed by appropriate heat treatment is an established process used to produce the Swiss blue color, and when performed and stabilized correctly the resulting hue is durable under normal wear conditions. The combination of medium intensity color, very slight inclusions at eye level, and excellent polish yields a gem that presents with clarity and presence suited to a definitive central element in jewelry. For clients and designers seeking a transparent, well cut, and visually engaging blue topaz with measurable dimensions and documented attributes, this piece offers predictable performance and a clear profile for design planning. The Natural Gemstone Company can supply additional imagery and measured reports upon request, to assist in evaluation and to facilitate integration into a finished design.
