2.31 Ct. Swiss Blue Topaz from Ceylon (Sri Lanka)

This transparent 2.31 carat round Swiss blue topaz from Ceylon Sri Lanka presents exceptional visual appeal and technical merit, with precise dimensions of 7.85 by 7.93 by 5.26 millimeters, a mixed brilliant cut, and an excellent polish. The mixed brilliant faceting is optimized to balance pavilion depth and crown faceting to produce lively return of light, and this craftsmanship, together with the gem being very very slightly included as evaluated at eye level, creates a near flawless face up appearance that enhances scintillation from every angle. The medium color intensity of the Swiss blue tone is evenly saturated across the table and girdle, delivering a crisp cool blue that reads well in both daylight and artificial lighting conditions. The stone is transparent and free from any cloudiness, which allows each facet to act as an optical window for internal light play and for external reflections, so the gem appears lively and clean even under magnification. Enhancement by irradiation is disclosed for full transparency, and the resulting hue is stable when properly set and cared for, making this item suitable for daily wear thanks to topaz hardness on the Mohs scale.

For the informed buyer this topaz combines important valuation factors that support its desirability, namely weight at 2.31 carats, a consistent medium color, skilled mixed brilliant cutting, and an evaluated clarity of very very slightly included at eye level which implies minimal impact to appearance and light performance.
