1.82 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

I am pleased to present a transparent, vibrant 1.82 carat round bluish green sapphire, measuring 7.05 x 6.99 x 4.73 millimeters, cut in a mixed brilliant style, with a clarity grade of very slightly included when evaluated at eye level, intense color intensity, and an excellent polish. This sapphire has been heat treated, a standard and stable enhancement that improves both color and clarity while leaving the natural origin characteristics intact, and it comes to you from Ceylon Sri Lanka, a source renowned for producing some of the most lively and saturated sapphires in the world. At The Natural Sapphire Company we focus on providing fully described gemstones with transparent details about their cutting, clarity, treatment, and origin, because these factors directly affect the stone quality, performance, and long term value for an educated buyer. The mixed brilliant cut that has been applied to this round sapphire is designed to marry the scintillation of a brilliant style with facets that enhance the stone color, producing a gem that reads as both lively and deeply saturated, with excellent polish giving a clean, glassy surface that maximizes light return.

Understanding the clarity grade of very slightly included at eye level is important when assessing value and durability, and this sapphire balances clarity with natural character. Very slightly included means that any inclusions present are small, well healed, and not distracting to unaided observation, allowing the eye to appreciate transparent, even light transmission across the table and crown. At this clarity level the stone remains visually clean and luminous, which is especially important for stones in the two carat range where inclusions, if present, can be more apparent. The excellent polish indicates that the lapidary attention to facet finish was meticulous, reducing surface graining and increasing crisp reflections, which in turn enhances apparent brilliance and sparkle. The mixed brilliant cut places a strategic arrangement of facets that captures and returns light as bright, white scintillation while simultaneously concentrating color within the pavilion and crown, this balance makes the gem appear both lively and deeply colored under a variety of viewing conditions, and it also helps the stone retain strong presence even when set in jewelry.

Color and provenance are central to the appeal of this sapphire, and the bluish green hue combined with intense saturation reflects both trace element chemistry and Ceylon origin characteristics. Sapphires from Sri Lanka often display a lively, velvety presence, and the bluish green in this example suggests a balance of iron based tones producing green, with iron and titanium contributions producing blue, resulting in a teal to oceanic cast that is highly desirable. The intense color intensity means the saturation is strong without being overly dark, allowing the faceting to display both depth and clarity simultaneously, which is a hallmark of top quality sapphires for the educated buyer. Heat treatment is commonly used to enhance this balance by reducing inclusions and optimizing color, and when performed correctly it is stable, widely accepted in the market, and disclosed as it is here. Origin from Ceylon adds provenance value because collectors and connoisseurs associate that island with a spectrum of vivid and desirable sapphire colors, particularly those that are bright and medium to intense in tone, making this gem an attractive and meaningful choice for investment or for a significant custom commission.

How this sapphire will perform under different lighting conditions is one of its most compelling attributes, and the mixed brilliant cut together with high transparency ensures a dynamic response across lighting environments. In strong natural daylight the gem will display crisp white scintillation and lively flashes of light, while the intense bluish green hue will read vibrantly, appearing slightly cooler and more blue in direct midday sun. Under warm incandescent or candlelight the stone will show richer, deeper tones, with the green components becoming softer and the overall appearance taking on a velvety depth that is intimate and jewel like. In modern LED lighting the gemstone will exhibit sharp, clean brilliance and a brisk, lively scintillation, with directional flashes that emphasize the mixed facet structure, and in low ambient light the high transparency and polished facets will preserve a clear color identity, maintaining presence and making the gem visible without the need for bright illumination. Additionally, sapphires can display pleochroism, showing subtle shifts between blue and green tones as the stone is rotated, and this specimen will benefit from that optical character, offering visual interest and variety to the wearer. For mounting, a white metal setting will maximize the stone scintillation and emphasize cooler blue notes, while a yellow gold setting will warm the appearance and bring forward the greenish teal character, both approaches are valid depending on stylistic preference. At The Natural Sapphire Company we encourage viewing gemstones in several light types before finalizing a setting, and we can provide photographs and grading details to help you make an informed decision, this sapphire represents a strong combination of carat weight, transparent clarity, intense color, skilled cutting, and reputable Sri Lankan origin, qualities that serious buyers look for when seeking a stone with both aesthetic appeal and enduring value.
