1.35 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 1.35 carats, and measures 7.02 by 5.02 by 3.88 millimeters, presented in a classic emerald cut. The stone exhibits a vivid color intensity, with a saturated and well distributed blue that is characteristic of fine Ceylon origin. Clarity is graded as very slightly included, evaluated at eye level, a grade that indicates minor internal features that do not detract from the gem when viewed without magnification. The cutting and polish are executed to an excellent standard, producing crisp facet junctions and a clean table plane that enhance both color and light performance. The sapphire has undergone a standard heat treatment, a widely accepted enhancement for sapphires that improves tone and saturation while remaining stable under normal wear and maintenance. This gemstone is offered and presented by The Natural Sapphire Company, with full disclosure of its measurements, origin, clarity, and enhancement.

The emerald cut presents a refined geometry, with step facets that emphasize color and clarity rather than brilliance alone, creating a measured and elegant appearance. The shape and faceting pattern allow the vivid blue to show in broad, even flashes across the table, while the depth and pavilion angles have been balanced to retain color saturation without appearing overly dark. The excellent polish contributes to surface brightness and a pleasing luster, and the transparency permits a clean interaction of light with the internal structure. The very slightly included clarity grade means that inclusions are minimal and typically not visible to the unaided eye, which preserves the gem quality while providing a natural fingerprint of origin. Ceylon sapphires are known for their lively and complex blues, and this stone exemplifies that character through its combination of hue, tone, and clarity.

The combination of an emerald cut and the inherent durability of corundum makes this sapphire versatile for a wide range of settings and uses. Sapphire ranks nine on the Mohs hardness scale, which supports daily wear in rings, bracelets, pendants, and earrings, and the robust nature of the stone accommodates both secure prong settings and protective bezel mounts. In a casual context this sapphire provides a refined counterpoint to everyday attire, pairing well with both lighter and darker metals, and adding a considered touch to daytime looks. In formal settings the stepped facets and vivid color present a composed and sophisticated presence, where the stone contributes a measured elegance without dominating an ensemble. The clean lines of the emerald cut lend themselves to modern minimalism and to vintage inspired designs, enabling the gem to function as a focal point or as part of a complementary suite with side stones.

The Natural Sapphire Company provides transparent documentation and support for this sapphire, including details of origin and treatment upon request, and guidance on appropriate settings and care. Heat treatment in sapphires is a permanent enhancement that is stable under typical wearing and cleaning conditions, however routine professional checks and prudent handling are recommended to preserve the mounting and to ensure the stone remains secure. Cleaning with mild soap and warm water and a soft brush is effective for routine maintenance, and professional ultrasonic cleaning can be considered depending on the setting and any secondary treatments, with a professional evaluation advised prior to use. For clients seeking additional information on matching stones, setting options, or certified reports, our specialists at The Natural Sapphire Company are available to provide technical details and measurements, enabling a confident selection process that respects both the gemology and the aesthetic intentions of the purchaser.
