0.81 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This entry from The Natural Sapphire Company is a transparent 0.81 carat cushion shape blue sapphire with dimensions 5.67 by 5.64 by 3.23 mm. The stone is cut in a mixed brilliant style that balances facet arrangement for both depth of color and scintillation, and it has been given an excellent polish that produces crisp, even facet reflections. Color is described as vivid in intensity, presenting a rich and saturated blue that remains lively under varied lighting. Clarity is graded as very very slightly included, evaluated at eye level, indicating that the gem reads as visually clean to the unaided eye while retaining the natural internal features consistent with a natural origin. Enhancement is heat treated, a standard and stable practice in sapphires, and the parcel origin is Ceylon, Sri Lanka, a source known for producing lively, intensely hued blue sapphires.

Inclusions in this sapphire are subtle, and they function as natural identifiers that contribute to the gemological character of the stone. Under magnification the sapphire displays fine, minute features, including tiny crystal inclusions and delicate silk like threads and faint growth zoning typical of corundum from this region. These internal markers are not blemishes in the cosmetic sense, rather they are analogous to a fingerprint for the gemstone, offering certifiable evidence of natural formation and historical provenance. Because the clarity is assessed as very very slightly included at eye level, the internal features do not interfere with transparency or light transmission, and they are not noticeable in normal wear. The presence of natural inclusions also aids matching when a pair of stones is required, and provides durable confirmation in gemological reports, without detracting from the stone surface, polish, or overall visual appeal.

From a practical and design perspective this cushion sapphire is well suited to a range of settings where color and clarity are priorities. The mixed brilliant cut concentrates return of light through the crown, so the vivid blue color remains the dominant visual attribute, while the excellent polish enhances sparkle on movement. The modest dimensions and weight make the stone appropriate for a center stone in a delicate ring, a refined pendant, or as the focal point in bespoke jewelry where careful setting will protect the girdle and corners of the cushion outline. Consideration of metal choice will influence perception of color, white metals such as platinum or white gold will emphasize the sapphire sparkle and cool tones, while warm metals such as yellow gold will create contrast that can intensify perceived saturation. As corundum, sapphire rates high for everyday wear, and conventional care is sufficient, with avoidance of harsh chemicals and strong thermal shock recommended, and professional cleaning can be arranged when needed.
