1.59 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.59 carat emerald cut blue sapphire presents a measured and restrained elegance, with dimensions of 7.00 by 4.79 by 4.75 millimeters. The stone is transparent, with a clarity grade of very, very slightly included, evaluated at eye level, and an excellent polish that contributes to crisp facet definition and refined light return. The color displays medium intensity along a cool blue axis, with even distribution across the table and pavilion, and the gem has undergone standard heat treatment to optimize hue and clarity without altering its natural identity. The emerald cut emphasizes linear geometry and step facets, producing broad, luminous planes that reveal the sapphire s internal color and clarity characteristics in a way that is distinct from brilliant or mixed cuts. For clients and designers seeking a balanced combination of classic form and subtle color presence, this stone offers a clear specification package, suitable for precise settings and proportionate mounting designs.

Optically, the sapphire s emerald cut and excellent polish create strong facet outlines and a defined hall of mirrors effect that moderates flash and scintillation in favor of controlled, even light movement. The medium color intensity places the gem in a tonal region that reads neither deeply saturated nor pale, and the hue skews toward a cool, slightly silvery blue rather than a warm or heavily inky blue. At this scale and cut, the very, very slight inclusions remain unobtrusive to the unaided eye, contributing to the stone s overall transparency while offering internal features that are typical for natural material. The pavilion depth and table proportions are managed to preserve face up size, while the step facet arrangement enhances the perception of depth and color zoning control, making the gem a practical choice for settings where clarity, table presence, and an understated blue are priorities.

When compared to sapphires from other renowned origins, this Ceylon, Sri Lanka example reveals characteristic regional tendencies in both hue and tone. Classic Kashmir sapphires are renowned for a deep, velvety cornflower blue with a softened, almost powdered tone and exceptional saturation, qualities that are not mirrored here, as the present stone exhibits a lighter, more transparent blue with a cooler, silvery undertone. Burmese, or Myanmar, sapphires often present richer, more intense royal or deep blue tones with stronger saturation and warmth than this Ceylon gem, so the present stone reads as more delicate and airy in comparison. Australian sapphires tend to be darker and more inky, occasionally with greenish overtones, which contrasts with the clarity and cooler brightness of the Ceylon sapphire on offer. Madagascar produces a wide range of blues, some closely approaching Ceylon s lighter, vivid styles, and in many cases Madagascan material can be similar in tone but may differ in the way light is returned due to cutting preferences and crystal habit.

Further comparison highlights how the sapphire s medium intensity and cool hue align it with the more transparent, luminous spectrum associated with Ceylon origins, while distinguishing it from other geographic typologies. Montana sapphires, for example, frequently exhibit steelier, teal tinges and generally sit at a lower saturation, which makes them feel more subdued and earthy relative to this gem s cleaner blue. Conversely, some Madagascan or Thai sapphires may present warmer or greener biases, shifting a gem toward turquoise or teal, neither of which is apparent here. The emerald cut accentuates the stone s Ceylon character, presenting the cooler blue in planar facets that emphasize clarity and color consistency rather than the velvety diffusion prized in Kashmir stones. The Natural Sapphire Company presents these comparative observations to inform design choices and provenance preferences, acknowledging that origin related expectations are useful guides, while individual stones must be assessed on their own optical and structural merits.

In practical terms, this sapphire s size, cut, and face up appearance make it well suited to a variety of fine jewelry applications where a refined, cool blue is desired, including solitaire and three stone ring designs, as well as more contemporary bezel or channel mountings that benefit from the emerald cut s linear silhouette. The medium color intensity allows the gem to pair effectively with both white and yellow metals, although the cooler blue typically harmonizes more quietly with platinum and white gold, accentuating the stone s silvery overtones. Heat treatment is a common, widely accepted enhancement that stabilizes and refines natural color and clarity, and the treatment here is disclosed consistently with industry standards.
