1.99 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent cushion shape blue sapphire weighs 1.99 carats, and measures 8.02 x 5.52 x 4.53 mm. The gem is cut with a mixed brilliant facet arrangement, combining a brilliant style crown with a more structured pavilion to achieve both strong color saturation and lively scintillation. Clarity is graded as eye clean at normal viewing distance, indicating that no inclusions are readily visible without magnification. Color intensity is vivid, presenting a deep blue that is characteristic of fine Ceylon origin sapphires. The gemstone has been heat treated to enhance its tone and clarity, a stable and commonly accepted enhancement in the trade, and the polish is graded excellent, resulting in crisp facet junctions and very smooth facet planes. The provenance from Ceylon Sri Lanka is noted, and the gem has been selected and presented by The Natural Sapphire Company.

Under varied lighting conditions this sapphire displays consistent and appealing optical behavior. In natural daylight the stone exhibits its truest blue, a vivid medium to deep blue that remains saturated without appearing overly dark, with the mixed brilliant cut allowing the crown facets to return strong blue flashes across the table. Under cool daylight or north light the gem leans toward a pure, slightly velvety blue, with distinct internal reflections that emphasize depth. In warm incandescent lighting the tone becomes richer and slightly warmer, revealing subtle blue violet undertones while maintaining overall saturation. Under modern LED or full spectrum lighting the sapphire shows heightened contrast between bright facet reflections and darker color windows, producing crisp scintillation and lively movement as the stone is viewed or as it tilts. In low level or candlelight the sapphire retains a dignified presence, showing concentrated flashes and a sense of depth rather than broad dispersion, as sapphires exhibit lower fire than colorless gemstones but excel in color saturation and facet scintillation. When set with an open pavilion or used with backlighting the gem can reveal internal zoning and fine facet reflections, enhancing the perception of clarity and structure without compromising the vivid color.

For jewelry design and daily wear considerations this cushion sapphire balances presence and practicality. The dimensions and mixed brilliant cut make it well suited for a ring center stone, a classic pendant, or a sophisticated custom mount, where the excellent polish will translate into crisp visual impact once set. The heat treatment applied is stable and routine, and standard care practices for corundum gemstones apply, including avoiding prolonged exposure to harsh chemicals and sudden thermal shock, and occasional professional cleaning to preserve the polish and brilliance. The eye clean clarity grade and vivid color intensity mean the gem offers strong visual appeal without requiring loupe inspection to appreciate its quality. The Natural Sapphire Company provides detailed imaging and handling guidance for setting, and our gemologists can advise on complementing metal choices and setting styles that will maximize the sapphire's light return and color performance in real world wear.
