1.40 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.40 carat oval shape blue sapphire, measuring 6.82 x 5.14 x 4.16 millimeters, presents an ideal balance between presence and wearability. The mixed brilliant cut combines the depth and color concentration of step facets with the scintillation and light return of brilliant style faceting, producing lively fire and even color distribution across the table. With an intense color intensity and an excellent polish, this gem gives an immediate impression of richness without appearing overly dark, which makes it visually striking under both daylight and artificial lighting. The elongated oval outline enhances finger coverage in a ring setting while preserving a classic proportions profile that flatters many jewelry designs. For an educated buyer who appreciates how cut, proportions, and finish interact, this sapphire demonstrates thoughtful cutting decisions that maximize both color and brilliance from a moderately sized rough.

Clarity is an important consideration in sapphires, and this stone is graded very slightly included, evaluated at eye level, which places it among the more attractive clarity grades available for natural material. Very slight inclusions mean that any internal features are minimal in size and distribution, and they do not distract from the overall face up appearance when the gem is worn. Evaluated at eye level indicates that the gem was assessed for what an observer will actually see, as opposed to microscopic grading that can emphasize inclusions inconsequential to daily enjoyment. The excellent polish further minimizes any optical interference, allowing light to pass and reflect cleanly. This sapphire has been heat treated, which is a stable and widely accepted enhancement in the trade, used to refine color and clarity without compromising structural integrity, when properly performed. Heat treatment in sapphires typically produces permanent improvements and does not require further maintenance, a fact that educated buyers routinely accept when paired with full disclosure.

Origin is a key factor for connoisseurs, and this sapphire comes from Ceylon, Sri Lanka, a source with a long and esteemed history for producing bright and lively blue stones. Ceylon sapphires are often prized for their clarity and a distinct, vivid blue that tends to be lighter and more luminous than the deep velvet blue associated with some other sources, which allows them to appear more vibrant and versatile in different settings. The geological conditions in Sri Lanka create a balance of trace elements that produce this desirable hue, and collectors recognize provenance as a meaningful component of value. At 1.40 carats and with an oval outline of these exact dimensions, the gem offers a pleasing face up area that appears generous for its weight, particularly because the mixed brilliant facets enhance light return. The polished finish and facet placement mean this sapphire will sit beautifully in a fine mounting, and its proportions accommodate a variety of designs, from a solitaire engagement setting to a bezel set pendant that emphasizes the color and shape.

Beyond immediate appearance, sapphires are renowned for lasting beauty and practicality, which is an important aspect for buyers seeking a gem that will continue to captivate over the years. Corundum, the mineral species of sapphire, ranks 9 on the Mohs hardness scale, making it exceptionally resistant to scratches and abrasion compared with most other gemstones, which preserves polish and facet crispness over long periods of wear. The combination of stable heat treatment, excellent polish, and durable material ensures that the intense blue of this stone will remain luminous rather than dulling with time, provided basic care is observed. Simple cleaning with warm water, mild detergent, and a soft brush keeps the gem at peak brilliance, and periodic inspections of the setting will prevent loss or damage. For collectors and those making a considered purchase, the appeal of this Ceylon sapphire lies in its balance of natural origin, aesthetic quality, and practical longevity. The Natural Sapphire Company stands behind each gem and can provide further documentation and guidance for setting and care, making this 1.40 carat oval blue sapphire an informed choice for an educated buyer seeking both beauty and enduring value.
