0.93 Ct. Bluish Green Sapphire from Tanzania

This transparent 0.93 carat oval bluish green sapphire measures 5.88 by 4.88 by 3.80 millimeters, and it is a natural, unenhanced gem sourced from Tanzania. The stone presents an intense color intensity that balances blue and green tones in a way that reads uniformly when viewed face up. Clarity is described as very slightly included at eye level, indicating that inclusions are minimal and do not materially interfere with the gem s overall transparency. The cutting style is a mixed brilliant cut, and the surface shows an excellent polish, attributes that together contribute to a clean, lively appearance. This sapphire is offered by The Natural Sapphire Company, and it carries the hallmark qualities that characterize carefully selected, untreated material from reputable origins.

The mixed brilliant cut employed for this oval sapphire is specifically chosen to maximize the stone s interaction with light, enhancing both brilliance and color saturation. Mixed cutting combines the broad reflective planes and contrast of step facets with the multidirectional dispersion characteristics of brilliant facets. In practice this means the crown and pavilion geometry are arranged to redirect incident light back through the table and face of the gem, producing a high degree of return rather than allowing light to escape through the pavilion. The oval outline influences the distribution of light across the face of the gem, and controlled facet placement mitigates typical oval issues such as uneven brightness or an overly pronounced dark area along the long axis. The measured depth of 3.80 millimeters relative to the average diameter of 5.38 millimeters yields a depth to average diameter ratio of approximately 0.71, a proportion that supports effective internal reflection while maintaining a pleasing face up spread. Together the proportioning and mixed faceting create a dynamic balance between scintillation, which is the play of light with movement, and broad flashes of return, which enhance perceived size and color saturation.

The mixed brilliant faceting also amplifies dispersive flashes and localized contrast, creating a lively interplay of small bright points and deeper color zones. Brilliant facets break incoming light into multiple directions, increasing scintillation and the perception of brightness, while step facets contribute to larger mirrors that emphasize the gem s inherent color. For a bluish green sapphire with intense saturation, this combination accentuates the stone s hue without relying on excessive depth, preserving a well distributed color that reads consistent from different viewing angles. The excellent polish sharpens facet junctions so that light reflects cleanly across the surface, producing crisp, mirror like facets that minimize surface diffusion and maintain strong, focused return. Because the sapphire has not been treated, its pleochroic tendencies remain natural, and the faceting is executed to present the most attractive face up color while allowing subtle shifts in tone to appear as the stone moves.

Clarity that is very slightly included at eye level paired with excellent polish means the inclusions are unlikely to distract in ordinary wear, and the stone will present well in a variety of jewelry settings. In ring applications the mixed brilliant cut will accentuate lively scintillation and color, while in pendant or stud settings the balance of brilliance and broad color return will create an immediate and consistent visual impact. The lack of enhancement confirms that the color and clarity observed are intrinsic characteristics, and the origin of Tanzania provides context for the gem s natural formation and provenance. The Natural Sapphire Company inspects each specimen for cut execution, polish quality, and optical performance, ensuring that this 0.93 carat oval bluish green sapphire meets rigorous standards for proportion and finish before it is offered to clients.
