1.52 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.52 carat emerald cut shape blue sapphire, measuring 7.76 x 5.59 x 3.64 mm, offers a refined combination of geometry and optical purity that will appeal to the discerning buyer. The stone is faceted in an emerald cut, a style that emphasizes broad step facets and a large table, producing strong, mirror like flashes and a clean, architectural appearance when set. With an eye clean clarity grade as evaluated at eye level, the surface and interior present no obvious inclusions to the naked eye, which magnifies the sense of transparency and depth. The medium color intensity sits in a sweet spot for Ceylon origin material, providing a vivid presence without overwhelming darkness, and the excellent polish ensures that each facet edge reads crisply under direct light. This sapphire has been heat treated, a stable and widely accepted enhancement in the trade used to refine color and clarity, and its origin is Ceylon, Sri Lanka, a region historically celebrated for producing blue sapphires with lively tone and velvety brilliance. At The Natural Sapphire Company we present this gem as a precise meeting of traditional origin, careful cutting, and industry standard enhancement, ready to be appreciated for both its aesthetic qualities and its investment grade characteristics.

From a gemological grading perspective this sapphire offers multiple attributes that give it value to an educated buyer. The carat weight of 1.52 carat combined with the stated dimensions produces a balanced face up size, offering presence in a ring or pendant while maintaining proportional elegance. The emerald cut plays a decisive role in how the stone is read visually, because the step facets and expansive table prioritize color uniformity and broad reflective planes over the intense scintillation of brilliant cuts. The eye clean clarity grade means that the viewer will enjoy uninterrupted color flow and surface brightness without the distraction of visible inclusions, which also offers advantages for longevity and wearability. Heat treatment in this instance is consistent with industry norms for Ceylon sapphires, applied to enhance the stone in a stable manner without compromising its structural integrity, and it is a widely accepted practice among collectors and connoisseurs. The excellent polish is significant for light performance, because well finished polish increases light return and facet definition, translating into a more lively appearance in everyday wear. Origin matters to collectors, and Ceylon, Sri Lanka is prized for producing sapphires that often display a lively, bright blue rather than the overly dark saturation favored in other regions, which can influence both market desirability and historical provenance.

When comparing reflective qualities to other gemstones in its category, the emerald cut Ceylon sapphire has a distinct visual language that sets it apart. Against brilliant cut sapphires, which rely on numerous small facets to create a strong scintillation effect and dispersed sparkle, the emerald cut yields broader, cleaner flashes and a more mirror like lustre, so the gem reads as classically elegant rather than vigorously sparkling. Compared to Kashmir and Burmese sapphires, which are often sought for their uniquely deep and velvety tonal saturation, a medium intensity Ceylon stone will appear brighter and more lively, exhibiting a fresher, airier reflection that enhances visibility under varied lighting. Versus other blue gemstones such as spinel, aquamarine, and topaz, this sapphire will show richer color depth and a different type of light return, because sapphire has a higher refractive index and stronger color persistence, resulting in denser color planes and less watery light diffusion than aquamarine. Compared to colorless diamonds, the sapphire does not display the same high dispersion or fire, but it compensates with saturated hue and pronounced pleochroism in some orientations, giving a changing depth of blue that adds character rather than spectral flashes. In practical terms for setting design, the emerald cut shape lends itself to a refined aesthetic where broad facet reflections play with light in measured ways, making the gem ideal for buyers who value color purity and compositional clarity. At The Natural Sapphire Company we can place this sapphire into settings that maximize its step facet reflections and emphasize its eye clean clarity, and we welcome inquiries from clients who want detailed photos, lighting studies, or comparative examples from different origins to aid a fully informed purchase.
