1.10 Ct. Purple Sapphire from Ceylon (Sri Lanka)

This transparent round purple sapphire weighs 1.10 carats and measures 6.14 by 5.90 by 3.79 millimeters, cut as a mixed brilliant to combine the lively scintillation of a brilliant crown with the color depth and face up presence produced by a stepped pavilion. The overall depth measures approximately 63 percent of the average diameter, a proportion that supports strong light return while preserving visual diameter on the finger. Clarity is graded slightly included at eye level, meaning small natural inclusions are present but do not materially interrupt transparency or windowing. Color is medium intensity purple with balanced violet and lilac components that read as true purple in neutral light. The polish is excellent, giving mirror like facet surfaces that enhance sparkle. This stone has been heat treated, a stable and common enhancement for sapphires, and its origin is Ceylon Sri Lanka, a source known for clean crystals and refined tone. The Natural Sapphire Company presents this stone as an example of precise cutting and consistent material quality.

Under daylight and neutral natural light the mixed brilliant faceting disburses light across numerous small flashes, revealing a true medium purple with subtle violet undertones, the stepped pavilion layers deepening the body color in the center while the brilliant crown delivers peripheral scintillation. Under warm incandescent lighting the purple takes on a slightly warmer aspect, leaning toward pinkish purple as longer wavelengths are accentuated, and the stone appears fuller and more saturated. Under cool LED or fluorescent lighting the stone displays the cooler violet spectrum more strongly, increasing contrast between flashes and areas of color saturation, which enhances perceived brilliance. Under a focused spotlight or display lamp the well executed crown facets produce acute pinpoint flashes and dynamic contrast, while the pavilion steps give a deep, velvety eye rather than a washed appearance. In low ambient light the medium color intensity preserves presence without appearing murky, and the excellent polish maximizes available reflectance so that the gem remains lively even with limited illumination.

For mounting the mixed brilliant purple sapphire benefits from an open setting or minimal bezel to allow light ingress and egress, and a white metal setting will emphasize sparkle while yellow metal will warm the tone. Given the slightly included clarity grade placing inclusions toward the girdle or under prongs can further minimize visibility. Heat treatment is stable under normal wear and routine jewelry maintenance, and the proportions and finish reflect careful cutting intended to optimize both face up beauty and optical performance. The Natural Sapphire Company recommends this 1.10 carat Ceylon sapphire for a solitaire or halo application where both refined purple color and precise light performance are desired.
