0.66 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are searching for a sapphire that ends the search and becomes the piece you reach for first, this 0.66 carat Ceylon trillion sapphire from The Natural Sapphire Company is exactly that solution, a gem that reads as both a classic and a modern statement. The triangular trillion cut, at 5.11 by 5.95 by 2.96 millimeters, has been executed with precision, producing crisp facets and an excellent polish that lets the stone breathe and flash with every movement. Its transparency combined with a clarity graded as very very slightly included at eye level gives you a gemstone that sparkles with clarity while carrying the subtle, natural fingerprint that tells the story of a real, unenhanced gem. With intense color intensity and no heat or other enhancement, this sapphire is a true Ceylon treasure, lively and honest in hue, ready to be set as a distinctive engagement center or kept as a rare collectible that will age gracefully.

When comparing hue and tone to sapphires from other famous sources, the differences help you understand why collectors prize origin and why this Ceylon stone has such broad appeal. Classic Kashmir sapphires are known for their velvety, cornflower blue with a soft diffusion of light that creates a sumptuous, almost powdered appearance, and those stones often sit in a deeper, more luxurious tone that feels very plush. In contrast, Burmese and Sri Lankan sapphires tend to be brighter and more lively, and this trillion captures that bright, vivid Ceylon character while maintaining a stronger intensity than many Sri Lankan stones that can sometimes be lighter. Compared to Burmese examples that sometimes lean toward a richer, royal blue, this Ceylon trillion reads as more luminous and energetic, with a clarity that makes its intense blue sing rather than brood, and that liveliness is part of what makes it so versatile for both classic and modern settings.

It is also instructive to set this trillion against sapphires from Madagascar, Australia, and Montana, so you can see how tone and hue shape the personality of a gem and why this piece will satisfy a collector or a bride looking for something singular. Madagascar sapphires can deliver spectacular saturation and a wide range of blue tones, often approaching the vividness you see in Ceylon material, but they sometimes show a slightly earthier depth that reads differently in daylight. Australian sapphires are famously inky, often darker and with more teal or green undertones, which lend a brooding, masculine appeal but do not convey the same luminous cheerfulness as this Ceylon trillion. Montana sapphires are generally paler and cooler in tone, with steel and icy blue notes that are delicate and refined, yet they lack the intense saturation of this stone. Placed side by side, this Ceylon trillion occupies the sweet spot between vivid and wearable, offering an intense, clean blue that is neither too dark nor too muted, and its tone has the hallmark Ceylon clarity and sparkle that photographers and designers love.

If your quest is for a stone that will finish an engagement ring design with unmistakable personality, or if you want a rare, unenhanced sapphire for a curated collection, this trillion is designed to meet that need. The unique triangular silhouette gives a modern edge to any setting, and because the stone is unenhanced and graded very very slightly included at eye level, you are buying integrity as well as beauty. Imagine it as the star of a delicate halo to amplify its brilliance, or as a minimalist solitaire to emphasize its intense Ceylon color and the crisp geometry of the trillion cut. At The Natural Sapphire Company we are committed to matching stones to the exact desire you describe, and we will help you envision settings that complement the stone s tone, whether you are drawn to a warm yellow gold to bring out blue warmth, a cool white metal to emphasize clarity, or a custom mixed metal design to capture both. This trillion sapphire answers the call for a gem that combines provenance, purity, and presence, and for customers who have been searching for that perfect balance between collector grade and wearable elegance, your search truly ends here.
