1.04 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shape blue sapphire weighs 1.04 carats and measures 5.87 x 5.14 x 3.46 mm, offering a balanced profile for a wide range of mounting styles. The gem is transparent and displays a light blue color intensity that reads as delicate and airy in daylight, while retaining clear saturation in indoor lighting. The mixed brilliant cut combines a faceted pavilion designed for optimized light return with restrained crown faceting to preserve weight and depth, producing a refined scintillation and clean face up appearance. Clarity is graded as very slightly included, evaluated at eye level, and these small internal characteristics do not detract from the overall visual appeal or brilliance. The polish is excellent, resulting in crisp facet junctions and a smooth surface that enhances luster. This sapphire originates from Ceylon Sri Lanka, and it has not undergone any enhancement, preserving its natural formation and characteristics. The Natural Sapphire Company provides this stone with full provenance information and standard gemological documentation upon request.

On the Mohs hardness scale this sapphire registers at 9, placing it among the hardest gem materials after diamond which is 10. This hardness makes corundum exceptionally resistant to abrasion and surface wear compared to commonly used jewelry gems such as topaz at 8 and quartz at 7, and it is significantly harder than beryl varieties which typically fall around 7.5 to 8. The combination of high hardness and excellent polish means this sapphire is well suited to everyday wear in rings and other jewelry that experience regular contact, while the cushion shape and mixed brilliant cut provide both durability at bezel or prong settings and attractive light performance. Routine care consists of gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemicals and ultrasonic cleaners if significant inclusions are present. For secure mounting and long term preservation The Natural Sapphire Company recommends professional setting and periodic inspection of the mounting to ensure the stone remains protected and performs as intended.
