0.71 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.71 carat round blue sapphire from Ceylon embodies a rich, bold color as a symbol of personal power and distinction, presented with technical precision and gemological clarity by The Natural Sapphire Company. The stone measures 5.33 by 5.38 by 3.41 millimeters, and its transparent body allows a full assessment of optical behavior and internal features. Origin is Ceylon Sri Lanka, a provenance known for producing sapphires with lively fluorescence and a characteristic vivid to intense blue hue. Enhancement is limited to traditional heat treatment, applied to improve clarity and color uniformity while preserving natural characteristics. The combination of size and optical purity in this 0.71 carat example makes it ideal as a principal gem for refined jewelry applications, where color dominance and technical cutting quality are paramount.

Cutting technique and finish are central to the performance of this mixed brilliant cut sapphire, where the cutter has married a brilliant crown with a modified pavilion to optimize both color saturation and light return. The crown facet arrangement disperses incoming light across multiple brilliant facets, while the pavilion geometry directs light back through the table and crown to maximize perceived depth and scintillation. The measured depth of 3.41 millimeters relative to an average diameter of 5.355 millimeters yields a depth ratio of approximately 63.7 percent, a slightly deeper profile that enhances color saturation without significant loss of brilliance. Facet junctions are crisp, symmetry is precise, and the excellent polish contributes to high surface luster and efficient internal reflection. These attributes work together to produce dynamic blue flashes and a controlled pattern of light and dark areas that emphasize the stone s structural geometry.

Color and clarity are the next layer of technical description, and they are exceptional in this specimen. Color intensity is classified as intense, with a primary pure blue hue and a high degree of saturation that reads rich and resolute in both studio lighting and natural daylight. The saturation leans toward a vivid, clean blue, with minimal secondary tones, and color distribution appears even across the crown and through the pavilion. Clarity is described as very very slightly included, evaluated at eye level, indicating that inclusions are minute and do not interfere with overall transparency or visual impact to an unaided viewer. Under magnification slight pinpoint or feather features may be detectable, but they do not impair the stone s structural integrity or optical performance. The heat treatment applied is a stable enhancement, commonly accepted in the trade, and it has been executed to improve clarity and to intensify the natural blue without over altering the stone s original character.

From a setting and design perspective this sapphire offers both technical versatility and a commanding aesthetic presence, ideal for clients who seek a gem that conveys authority and distinction through material excellence. The round mixed brilliant profile lends itself to classic solitaire settings where the gem serves as the focal point, as well as to halo or three stone designs that balance the intense blue with accent diamonds or complementary sapphires. Metals such as platinum or 18 karat white gold will enhance the stone s cool blue tones, while 18 karat yellow gold can introduce a contrasting warmth that amplifies the perception of depth and saturation. For those who prioritize documented provenance and expert handling, The Natural Sapphire Company provides detailed origin and treatment disclosures, along with expert mounting recommendations to preserve the stone s optical properties. This sapphire stands as a technical specimen and as a symbol, its rich bold color signifying personal power and distinction, and its precise cut and finish reflecting the craftsmanship that discerning buyers expect.
