6.64 Ct. Blue Sapphire from Ceylon (Sri Lanka)

From the moment this crystal began to form deep within the earth, its story has been one of slow, patient refinement, an elemental tale that ends in a singular experience of beauty, weight, and presence. This is a transparent blue sapphire, a superb example of Ceylon provenance, weighing 6.64 carats, cut into an elegant emerald shape, with exact dimensions of 11.35 by 8.68 by 6.74 millimeters, clarity evaluated as eye clean at normal viewing, intense color intensity, and an excellent polish. The gem has undergone careful heat treatment to stabilize and intensify its color, a traditional and accepted enhancement for sapphires, applied by skilled hands to reveal what nature intended. When you hold this sapphire, you hold both time and place, a piece of Ceylon, Sri Lanka, carried to you by The Natural Sapphire Company, offered precisely as it was assessed and finished by our master cutters and gemologists, ready to be set into a ring, a pendant, or a bespoke creation that celebrates its every facet.

The origin of this stone traces back to the famed gem lands of Ceylon, Sri Lanka, a place where sapphire history and human tradition have intertwined for centuries. In those alluvial deposits, under tropical skies and the patience of miners who read the veins of the earth, corundum crystals grew slowly, colored by trace elements that give Ceylon sapphires their often vivid, lively hues. Artisanal miners work with intimate knowledge of the land, following stories handed down through generations, and that legacy is encoded in each rough stone, including this one. The journey from the riverbeds and shallow pits of Ceylon to our workshops carries the whisper of monsoon rains, the labor of careful sorting, and the moral responsibility of sourcing practices that The Natural Sapphire Company supports, because provenance matters as much as beauty. Knowing that this sapphire was born in Ceylon, Sri Lanka gives it a cultural resonance that complements its physical attributes, making it more than an object, but a relic of place and human craft.

The transformation from rough crystal to the graceful emerald cut you see is where art meets precision. The emerald cut, with its long step facets and open table, was chosen to emphasize this sapphire’s clarity and to present its intense blue in broad, even planes that draw the eye inward. At 11.35 by 8.68 by 6.74 millimeters and 6.64 carats, the proportions were carefully balanced to maximize light performance while preserving as much of the natural weight as possible, a crucial consideration for a gem of this size. Eye clean clarity means that when examined with the naked eye at a typical viewing distance, the stone appears free of inclusions that could interrupt its luminous field, and the excellent polish gives each facet a mirror finish that sharpens contrast and intensifies color. Heat treatment has been applied with restraint and expertise to unlock and stabilize the vibrant Ceylon blue, never to deceive, but to reveal the gem’s highest potential. The result is a sapphire that reads as premium at first glance, with the kind of optical presence and crisp edged geometry that only a finely executed emerald cut can deliver.

A 6.64 carat weight is a statement, it marks this sapphire as an investment in rarity, presence, and timeless elegance, qualities that collectors and connoisseurs immediately recognize. Weight in carats is more than a number, it is a measure of the stone’s physical heft and the audacity of its visual impact, the difference between a whisper and a proclamation on the hand, or at the throat. For those seeking a centerpiece that carries both provenance and perfection, this Ceylon sapphire, presented by The Natural Sapphire Company, answers that call with authority. We stand behind every facet, offering detailed documentation of treatment and origin, and guidance on settings that will showcase the emerald cut and protect the stone for generations.
