2.00 Ct. Swiss Blue Topaz from Brazil

This marquise shape Swiss blue topaz presented by The Natural Gemstone Company is a transparent 2.00 carat specimen, with exact dimensions of 11.95 x 6.16 x 3.76 millimeters, and a length to width ratio of approximately 1.94 to one, yielding an elegant elongated outline suited to rings and pendants. The cutting style is faceted, executed as a mixed brilliant design that combines a brilliant style crown with a precision pavilion layout to maximize return of light and dynamic scintillation along the marquise profile. Color is graded as medium intensity, produced by controlled irradiation to achieve the trademark Swiss blue tone, and the gem exhibits a very slightly included clarity at eye level, with an excellent polish that allows clean facet junctions and crisp optical contrast between table, crown facets, and the pavilion. Origin is Brazil, and overall cutting and finish reflect careful proportioning to balance brilliance, depth distribution, and visual weight for a two carat marquise.

From a durability standpoint this topaz is highly appropriate for everyday jewelry when set and handled with considered care. Topaz registers eight on the Mohs hardness scale, providing robust resistance to most scratches encountered in daily wear, and the excellent polish and mixed brilliant faceting help conceal minor surface wear. Attention must be paid to topaz cleavage and brittleness, the mineral having a pronounced directional cleavage that makes sharp blows or hard knocks to facet junctions or the marquise points a primary risk. For daily settings we recommend protective mounting strategies such as a bezel or partial bezel for the pointed ends, or secure V prongs that cradle the tips, and avoid exposed thin girdles. The irradiated Swiss blue coloration is stable under normal light and usual wear conditions, however exposure to extreme temperatures, abrupt thermal shocks, and aggressive cleaning methods such as steam cleaning are best avoided. Gentle cleaning with warm soapy water and a soft brush, periodic inspection of the setting, and removal during heavy manual activity will ensure long term performance and retain the gemological qualities of this finely cut Brazilian topaz.
