2.27 Ct. Blue Sapphire from Thailand

This 2.27 carat oval blue sapphire presents precise proportions and thoughtful finishing, attributes that reflect the standards of The Natural Sapphire Company. The gem measures 9.45 by 6.67 by 3.71 millimeters, with a depth that works out to approximately 46 percent of the average diameter, a proportion that contributes to a broad face up and stable profile for setting. The cut is a mixed brilliant style, combining a faceted crown with a step influenced pavilion to balance scintillation and color retention. Transparency is described as transparent, the clarity grade is very slightly included when evaluated at eye level, and the polish is excellent. The stone has been heat treated, a standard and stable enhancement used to improve tone and saturation, and its documented origin is Thailand.

In hand and under natural daylight this sapphire displays a dark color intensity with a primary blue hue that reads deep and inky, with subtle cool modifiers. The surface shows controlled reflections and a restrained degree of brilliance, characteristics that are consistent with a darker tone and with a mixed brilliant cut designed to preserve color while adding facet scintillation. Pleochroic behavior is present as is common in corundum, with slightly different blue depths when viewed from different angles, which is observable in the provided profile images and in actual handling. The very slight inclusions do not distract from the face up appearance, and the excellent polish aids in smooth light return and a clean table window, providing a composed and elegant presence on the finger.

Comparing hue and tone to sapphires from other famous locations clarifies the identity of this stone. The deep, inky blue of this Thai sapphire is darker and more saturated than the classic Ceylon sapphire from Sri Lanka, which is often lighter and brighter with a more pronounced cornflower blue or vivid royal blue hue. By contrast this stone is closer in tone to many Thai and Australian material that favor a more intense, velvety blue that reads near midnight blue under lower light. When set beside a Kashmir sapphire, which is celebrated for its rare, softly diffused cornflower blue and a medium tone that carries a velvety silk like effect, this Thai example will appear notably darker and denser, with less of the luminous soft diffusion that gives Kashmir stones their signature glow.

A further comparison with gemstones from other notable sources reinforces the character of this sapphire. Burmese sapphires from well known sources in Myanmar can exhibit a vivid, saturated royal blue with a slightly warmer, sometimes more vivid saturation than Thai material, making them appear more vivid at matched depths. Madagascar sapphires often show a wide range of hues and can approach the deep tones seen here, but their color can be more variable and frequently shows stronger saturation shifts when viewed at different angles. Australian sapphires, including those described as dark or inky, can be very similar to this stone in both hue and tone, often producing the same near midnight effect that reads almost black under certain lighting conditions. Montana sapphires from the United States typically inhabit the lighter to medium blue to teal spectrum, and therefore present a distinctly brighter and more pastel face up compared with this dark Thai sapphire.

From a practical and gemological perspective this sapphire is well suited to a variety of fine jewelry applications, particularly in center stone roles where its 2.27 carat weight and broad oval face will make a defined visual statement without overpowering most mounting designs. The mixed brilliant cut has been executed to balance color retention with facet play, which is advantageous in darker stones where maximum light return at the table can prevent the stone from appearing flat. The clarity grade of very slightly included at eye level indicates inclusions that are minimal in their impact on the overall appearance and stability. The heat treatment is a common and accepted enhancement that improves tone and evenness, and the hardness and toughness of sapphire make it appropriate for everyday wear when set and maintained properly. For clients who value geographic origin, this stone carries the documented provenance of Thailand and the assurance of quality handling associated with The Natural Sapphire Company.
