5.35 Ct. Blue Topaz from Brazil

This transparent 5.35 carat blue topaz measures 16.04 by 11.86 by 6.25 mm, is fashioned in a fancy shape with a mixed brilliant cut, and displays a medium color intensity with an excellent polish. Clarity is graded as very slightly included when evaluated at eye level, which in practical terms yields an eye clean appearance for most settings and lighting conditions. The mixed brilliant cut combines step facets on the pavilion with brilliant facets on the crown, creating balanced light return that accentuates both table brilliance and internal scintillation. Originating from Brazil, and enhanced by irradiation to develop its stable blue hue, this gem represents a common and accepted treatment for topaz that produces predictable and lasting color when performed to industry standards.

When compared to more commonly known blue gemstones, this Brazilian blue topaz stands out for a number of measurable and practical reasons. Against aquamarine, which has a slightly lower refractive index, this topaz typically displays stronger return of white light and a crisper scintillation, due in part to the mixed brilliant faceting and its high transparency. Versus blue sapphire and zircon, which can show higher refractive indices and different optical behaviors, this topaz offers a cleaner, more open window to the stone at a fraction of the price per carat, while still offering attractive brilliance and fire for everyday jewelry. Topaz has a Mohs hardness of 8, making it durable enough for frequent wear with normal care, while its excellent polish maximizes surface reflectivity and contributes to perceived light performance. For the educated buyer seeking a statement size, the combination of weight, dimensions, eye level clarity, and the mixed brilliant design provides exceptional spread and visual impact without the premium pricing of classic gem species. The Natural Gemstone Company presents this piece as a reliably attractive and technically sound option for collectors and designers who value documented origin, clear grading notes, and stable enhancement practices.
