5.62 Ct. Blue Cabochon Sapphire from Ceylon (Sri Lanka)

This gemstone is a transparent 5.62 carat cushion shape blue sapphire, with dimensions of 9.26 by 9.24 by 6.29 millimeters, cut in a sugar loaf style, and originating from Ceylon, Sri Lanka, supplied by The Natural Sapphire Company. The stone displays an intense color intensity with excellent polish, and it has been evaluated as slightly included at eye level, a clarity grade that indicates small inclusions that do not overwhelm the stone when viewed face up. The sapphire has undergone routine heat treatment, a standard and widely accepted enhancement in the trade, applied to improve color saturation and overall clarity, and the combination of weight, transparent body, intense color, and careful finishing makes this a rare and desirable specimen for both collectors and connoisseurs seeking quality from a reputable source.

When assessing the quality of a sapphire, color is the primary determinant of value, and this Ceylon sapphire exhibits a deep, vivid blue that combines strong saturation with lively tone, creating a pleasing balance between depth and brilliance. Ceylon sapphires are known for their vibrant, lively blues that often present a slightly lighter, more luminous character than stones from other classic sources, and this example retains that regional character while achieving an intense presence that reads as rich and vivid in a variety of lighting conditions. The sugar loaf cut emphasizes color concentration and a soft, elegant play of light across the surface, producing broad flashes of blue rather than the scintillation associated with faceted brilliant cuts, and that effect is particularly attractive in larger stones where color and polish are the priorities. The excellent polish enhances surface luster and ensures clean light return, so the gem presents a satiny sheen and strong color at all angles.

Clarity described as slightly included evaluated at eye level means the inclusions are present but typically small, and they do not materially interfere with the gem's transparency or its face up appearance, and in many cases the inclusions are characteristic of natural origin and can actually support claims of authenticity. Heat treatment in sapphires is a stable, permanent enhancement when properly executed, and it is fully disclosure accepted by the market, it improves color and clarity without compromising structural integrity, and it does not diminish the desirability of the stone among educated buyers who value documented treatments and origin information. The 5.62 carat weight offers a substantial presence while remaining versatile for a fine ring or a pendant, and the near square cushion proportions, at 9.26 by 9.24 millimeters, make this an excellent candidate for a custom setting that showcases the gem core, while the 6.29 millimeter depth provides the necessary volume to maintain color richness and optical depth.

An educated buyer will recognize the combination of Ceylon origin, intense blue color, transparency, significant carat weight, and excellent polish as attributes that justify both aesthetic and investment interest, and The Natural Sapphire Company stands behind the provenance and treatment disclosures to ensure confidence in purchase. For everyday wear sapphires are among the hardest gem materials available with a Mohs hardness of 9, so this stone is durable enough for daily jewelry when set and cared for properly, and routine cleaning with warm soapy water and a soft brush is recommended, while avoiding exposure to extreme heat or harsh chemicals that could affect mounting adhesives or settings.
