0.68 Ct. Purple Sapphire from Ceylon (Sri Lanka)

This listing describes a single transparent marquise sapphire weighing 0.68 carat, with precise dimensions of 8.69 by 4.34 by 2.66 millimeters. The stone exhibits an intense purple hue and has been faceted in a mixed brilliant cut to balance scintillation and color saturation. Clarity is graded as very slightly included when evaluated at eye level, and the surface finish is described as excellent polish, which contributes to sharp facet definition and strong face-up brilliance. This sapphire has been heat treated, a common and stable enhancement for improving color and clarity, and its documented origin is Ceylon, Sri Lanka. The elongated marquise outline offers a traditional yet distinctive profile suitable for a variety of settings, and the measured depth of 2.66 millimeters indicates proportions consistent with good light performance for this size and weight.

From a durability perspective, this gem is corundum, placing it at 9 on the Mohs hardness scale, second only to diamond at 10. For practical comparison, quartz is 7 and topaz is 8, so this sapphire is markedly more resistant to scratching than many common gem materials. The high hardness means the stone tolerates everyday wear well and is suitable for rings, pendants, and earrings with standard precautions. Because the marquise shape has pointed ends, prudent setting choices such as protective prongs or V-shaped tips will reduce the risk of chipping from hard impacts, and routine checks of the setting are recommended. Heat treatment applied to this sapphire is stable under normal wearing and cleaning conditions, but avoid extreme thermal shock and direct, sustained exposure to harsh chemicals. For cleaning, warm soapy water and a soft brush are appropriate for maintaining appearance without risk to the enhancement.
