1.40 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Imagine a blue born deep beneath the tropical soils of Ceylon, where millions of years of heat and movement coaxed aluminum and traces of iron into the crystalline order of corundum. From those ancient flows a single, transparent oval arrived at our workshop, a gem that still carries the memory of its origin in every facet. This 1.40 carat blue sapphire measures 6.82 x 5.14 x 4.16 mm, a compact but commanding presence that reflects the island geology from which it was extracted. The mixed brilliant cut was chosen to balance sparkle and depth, and its medium color intensity allows light to travel through and play across its planes, revealing blue tones that shift with every turn. Evaluated at eye level the clarity grade is very slightly included, giving the stone an honest character that tells a natural story, while the excellent polish lets those surfaces sing. At The Natural Sapphire Company we believe every sapphire should arrive to its keeper with provenance and pride, and this stone is accompanied by the clear, simple truth that it has been heat treated to enhance its inherent beauty.

Weight is the language in which rarity and value most directly speak, and a 1.40 carat sapphire is a persuasive storyteller. Carat reflects mass not simply visible size, and in corundum that mass translates to lasting substance and presence on a hand or in a setting. As a gemstone climbs through the carat scale, each incremental increase is harder to find in clean material, because rough crystals of the right color and clarity of sufficient mass are rare. That is why a stone like this one, at 1.40 carat, commands attention beyond its millimeter dimensions. Cutters faced a choice when fashioning this gem, and skilled hands preserved weight while opening the stone to light with a mixed brilliant pavilion and crown. The result is a sapphire that reads larger than its dimensions might suggest, because the balance of depth and table maximizes visible area and fire. The very slightly included clarity grade tells you it is natural, not synthetically perfect, and that adds to collectible value. The medium color intensity offers versatility, flattering many metal tones and design styles, and the excellent polish ensures that every facet returns light with crisp clarity.

The journey from Ceylon mine to the case at The Natural Sapphire Company involved careful decisions at every stage, and the carat weight was central to each choice. When we examine rough material we map where inclusions lie, and we plan cuts to retain as much weight as possible while achieving the finest optical performance. For this sapphire that meant a disciplined approach to faceting, yielding the 6.82 x 5.14 x 4.16 mm oval form that sits beautifully on a finger, or anchors a custom pendant with quiet authority. Heat treatment was applied in a controlled fashion to deepen and stabilize the blue, a common and lasting enhancement that improves color without obscuring origin or character. For customers seeking a ring, a 1.40 carat oval creates a focal point that wears with elegance and everyday practicality, large enough to be noticed, modest enough to be comfortable. For collectors, this weight confirms the stone as a meaningful addition to a cabinet, because sapphires of Ceylon origin and this balanced combination of weight, cut, clarity, and color are items of persistent interest. At The Natural Sapphire Company we welcome conversations about settings that complement the sapphire s natural proportions, and we provide full disclosure about treatments and origin so that your choice is both informed and inspired.
