1.50 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing presents a transparent 1.50 carat blue sapphire, emerald cut, measuring 7.75 x 5.28 x 3.45 millimeters, a size and proportion that balance presence and wearability. The emerald cut is a step facet design that emphasizes broad, flat facets and a large table, a cut choice that requires a high degree of clarity and careful proportioning to achieve optimum face up appeal. With a depth of approximately 53 percent calculated from the given dimensions, this stone sits in a range that favors a generous face up appearance while maintaining good light return for this style of cut. The cut classically lends itself to an elegant, architectural aesthetic, offering crisp facet lines and a refined, understated sparkle rather than the intense scintillation of brilliant cuts. For the educated buyer this combination of weight, dimensions, and emerald cut reveals a deliberate selection that prioritizes color saturation and a clean window into the stone, delivering a gemstone that reads as both substantial and sophisticated.

Clarity and polish are essential considerations for a step cut sapphire, and this gem carries an eye clean clarity grade, evaluated at typical viewing distance with the unaided eye. Eye clean means no inclusions are visible to normal inspection, a valuable attribute in a stone with large step facets, because any internal features would be readily apparent. The excellent polish reported ensures crisp facet junctions, precise reflections, and a smooth surface that maximizes luster and tactile quality in finished jewelry. The combination of eye clean clarity and excellent polish allows the emerald cut to showcase the stone s internal color without distraction, a key advantage for buyers who prioritize visual purity and a refined appearance. These characteristics are particularly important to collectors and purchasers who appreciate transparency in grading and expect a strong correlation between the technical attributes of the stone and its visual performance.

Color and origin are central to this sapphire s appeal. The stone is described as having a dark color intensity, presenting a rich deep blue that is highly sought after by many clients. Dark color intensity in blue sapphires imparts a sense of depth and formality, ideal for designs where a sophisticated, saturated hue is desired. This sapphire originates from Ceylon, Sri Lanka, a historical source renowned for producing sapphires with lively tonal ranges and attractive brilliance. Ceylon sapphires are esteemed for their balance of color and clarity, and provenance from Sri Lanka carries recognition among connoisseurs who value documented origin. The heat treatment enhancement disclosed is an industry standard, stable, and permanent when properly performed. Heat treatment is widely accepted in the trade as an enhancement that improves color and clarity, and full disclosure of this treatment aligns with best practices for ethical sales and informed purchasing.

Durability and versatility are practical advantages that make this sapphire an excellent candidate for both everyday wear and more formal, statement pieces. Sapphire is corundum, a mineral with a hardness of nine on the Mohs scale, second only to diamond, making it highly resistant to scratching and suitable for rings, bracelets, and other items exposed to daily use. The emerald cut offers a refined silhouette that translates elegantly in a solitaire ring, a three stone setting, a modern bezel pendant, or refined cufflinks. In casual settings the stone s deep Ceylon blue and understated step flash provide a sophisticated but not ostentatious presence, pairing well with denim or business casual attire. In formal settings the same qualities project gravitas and elegance, particularly when set in platinum or yellow gold that complements the warm undertones often present in Ceylon blues. The combination of durability, size, and cut makes this sapphire a flexible choice for clients seeking a single stone that performs across diverse contexts.
