2.42 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a technically precise and visually compelling example, ideal for the buyer who values measured gemological detail. The stone weighs 2.42 carats, and its oval outline measures 8.64 x 7.37 x 4.41 mm, dimensions that give it a confident presence at the center of an engagement ring without overwhelming the finger. It has been cut in a mixed brilliant style, a facet design that combines step cutting on the pavilion with brilliant facets on the crown to maximize life and scintillation while preserving color. Transparency is excellent, and the clarity is graded very slightly included, evaluated at eye level, meaning any internal characteristics are subtle and do not interfere with the gem's face up appeal. Color is described as vivid in intensity, a saturated and lively blue that reads richly in both daylight and indoor light, and the stone receives an excellent polish so that individual facets return light crisply. The piece has been heat treated, a common and accepted enhancement in the trade to stabilize and intensify color, and the sapphire is of Ceylon origin, from Sri Lanka, a provenance long associated with finely colored blue sapphires.

From a gemological perspective the combination of Ceylon origin, vivid saturation, eye level clarity that is very slightly included, and a thoughtful mixed brilliant cut makes this a particularly attractive and balanced sapphire for an informed buyer. Sapphires from Sri Lanka are prized for their pure, lively blues that often sit between cornflower and royal tones, and heat treatment in this context refines the hue without compromising the structural integrity of the corundum. The very slightly included clarity grade reflects natural growth features rather than fractures, and because these features are minor at face up inspection they largely confirm the stone is natural and unfilled, attributes that collectors and connoisseurs recognize as valuable. The mixed brilliant cutting style enhances return of light and gives the oval a scintillating, lively surface that reads larger visually than weight alone might suggest. The excellent polish not only improves brilliance but also reduces wear over time by creating smooth facet junctions that resist surface abrasion.

As an engagement gemstone this 2.42 carat Ceylon sapphire offers a compelling combination of beauty, durability, and provenance, making it a practical and meaningful choice for everyday wear. Sapphire rates nine on the Mohs hardness scale, second only to diamond for the most commonly used gemstones in jewelry, and that inherent toughness makes it suitable for ring settings that are worn daily. For optimal protection while showcasing its vivid blue, settings such as a secure four or six prong solitaire, a bezel for low profile wear, or a halo that accentuates the stone size are recommended, and the mixed brilliant cut will respond well to either open prong or bezel styles depending on the desired balance between brilliance and protection. The color and size provide presence on the hand while remaining versatile with platinum or 18 karat gold, and the stone’s eye clean appearance means it will present as a clean, luminous centerpiece. At The Natural Sapphire Company we prioritize transparency about treatments and origin, and our team can provide additional imagery, independent laboratory reporting on request, and support for bespoke mounting and ring design to ensure that the final piece reflects both technical quality and personal meaning. If you are seeking a durable, ethically sourced, and visually striking engagement gemstone with codified gemological merits, this Ceylon blue sapphire represents a strong, informed choice.
