1.00 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent, Other certified yellow sapphire, weighing 1.00 carat and cut into a cushion shape with mixed brilliant facets, stands out for the way it handles light, and The Natural Sapphire Company is proud to present it as an exceptional choice for both design flexibility and lasting value. The stone measures 5.80 x 5.53 x 3.62 mm, has a clarity grade of very very slightly included at eye level, medium color intensity, and an excellent polish. Because it is unenhanced and originates from Ceylon Sri Lanka, its surface finish and facet precision are unencumbered by treatment artifacts, so the mixed brilliant cut can maximize return of light to the viewer. In practical terms this means lively scintillation and a warm, even field of yellow across the table and crown facets, with brightness that reads truer in natural light than many heated or diffusion treated yellow gems. The excellent polish sharpens facet junctions so that flashes of white light and colored sparkle are crisp, and the cushion outline gives a larger face up appearance than many round cuts of equivalent weight, which increases visual impact.

When compared to other yellow gemstones that buyers commonly consider, this Ceylon yellow sapphire offers superior optical performance and long term value. Corundum has a refractive index around 1.76 to 1.77, which is noticeably higher than quartz family gems like citrine at about 1.54 to 1.55, and higher than topaz at about 1.61 to 1.64, so a natural yellow sapphire returns stronger brilliance and more pronounced facet contrast under the same lighting. Against treated yellow sapphires and diffusion enhanced material, an unenhanced Ceylon piece shows more natural depth and stable color across viewing angles, and the very very slightly included clarity at eye level ensures sparkle without the cloudy or oily appearance that can occur in lower clarity stones. For buyers seeking a gemstone that reads lively on the hand, photographs well, and maintains both beauty and value over time, this cushion mixed brilliant yellow sapphire from The Natural Sapphire Company is a standout choice.
