3.09 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This natural blue sapphire is offered with a GIA certificate, it weighs 3.09 carats and is cut in a classic emerald shape. The measured dimensions are 8.63 by 6.46 by 5.93 millimeters, providing a substantial face up presence that balances table size and depth for a refined appearance. The stone is transparent, evaluated with a clarity grade described as very slightly included when viewed at eye level, and finished with an excellent polish that maximizes light return from the step facets. Color intensity is recorded as intense, and the material originates from Ceylon Sri Lanka, a region renowned for producing sapphires with lively and appealing blue tones. The sapphire has undergone customary heat treatment to improve color and clarity, a stable and widely accepted enhancement that does not alter the fundamental physical properties of the corundum, and The Natural Sapphire Company includes full documentation with the gem to confirm these details.

The emerald cut emphasizes the gem quality of this sapphire, the step facet arrangement creates broad planes of color and a measured interplay of light and shadow that highlights the stone core hue and saturation. At three carats plus, the stone offers a strong presence suitable for central settings in rings, pendants, or bespoke jewelry designs, while the rectangular proportions provide a refined silhouette that accommodates both traditional and contemporary mounting styles. The very slightly included clarity grading indicates that inclusions are minimal and not readily apparent to the unaided eye, a characteristic that complements the emerald cut which is sensitive to clarity due to its broad facets. The excellent polish enhances transparency and surface brightness, and the heat treatment history is disclosed to ensure full transparency about the gem provenance and preparation, consistent with the standards and practices upheld by The Natural Sapphire Company.

From a durability standpoint this sapphire is corundum, it records nine on the Mohs hardness scale, second only to diamond which is ten, this high hardness provides excellent resistance to scratches and abrasion for everyday wear. For comparison, common jewelry minerals such as quartz are seven on the Mohs scale, and topaz is eight, making this sapphire markedly more resistant to surface wear than those stones. Hardness is only one aspect of durability, the emerald cut does introduce angular corners that can be susceptible to impact if left unprotected, therefore settings that offer corner protection are recommended, such as bezel mounts or secure prong styles. Routine care is straightforward, warm soapy water and a soft brush will safely clean the stone, ultrasonics are generally acceptable for heat treated sapphires but use caution and consult a professional if the setting includes fragile components, avoid exposure to harsh chemicals and rapid temperature shock to maintain the integrity of the mounting and the gem. The Natural Sapphire Company provides the GIA report and professional guidance to assist in choosing an appropriate setting and to ensure the long term enjoyment and durability of this exceptional Ceylon blue sapphire.
