6.59 Ct. Yellow Sapphire Crystal from Ceylon (Sri Lanka)

This yellow sapphire offered by The Natural Sapphire Company is a semi translucent specimen weighing 6.59 carats, presented in a various shape form with dimensions 21.87 by 6.31 by 4.48 millimeters. The stone has been fashioned with a rough crystal cut that preserves the original crystal outline and growth features, while an excellent polish has been applied to the surfaces that were intentionally faceted and finished. Color evaluation yields a medium intense yellow tone, evenly distributed across the body of the crystal, and the material is entirely natural with no enhancement reported. Origin has been determined as Ceylon Sri Lanka, and the piece displays the characteristic warm hue and internal texture often associated with sapphires from that provenance.

Clarity is graded as slightly included, evaluated at eye level, which corresponds with visible but not dominant internal features when viewed unaided, and these inclusions contribute to the stone s natural character rather than detract from structural integrity. The elongated taper and rough crystal cut make this sapphire particularly suitable for bespoke or artisanal mounting approaches that celebrate natural form, with options including bezel settings that follow the profile or custom mounts that secure irregular shapes while maintaining visual balance. Light transmission through the semi translucent material produces a soft glow rather than mirror like brilliance, an attribute to consider when choosing complementary metals and setting styles. Care recommendations follow standard protocols for corundum, with avoidance of harsh chemical cleaners and impact that could chip pronounced edges, and professional cleaning and inspection are suggested after initial setting. For collectors and designers seeking a natural, unenhanced Ceylon yellow sapphire with evident crystal character and precise measured dimensions, this 6.59 carat rough crystal cut stone represents a reliable, documented option from The Natural Sapphire Company.
