0.67 Ct. Purple Sapphire from Tanzania

This 0.67 carat pear shape purple sapphire from Tanzania combines precise proportions with expert cutting to maximize color and light return, and is offered by The Natural Sapphire Company. The gem measures 6.49 x 4.55 x 2.91 mm and is executed in a mixed brilliant cut, with a brilliant style crown and a calibrated pavilion facet arrangement that balances broad flash and lively pinpoint scintillation. Clarity is graded very slightly included when evaluated at eye level, with internal features positioned and oriented so that they do not create significant windowing and have minimal impact on face up transparency. Color intensity is described as intense, exhibiting a saturated purple body tone with even distribution across the table and girdle, and polish has been graded excellent, producing crisp facet junctions and clean facet planes. No enhancement has been applied, preserving the natural tonal depth and crystal chemistry associated with Tanzanian corundum. The pavilion depth at 2.91 mm is proportioned to favor efficient light return while retaining a pleasing table face and a strong silhouette suitable for precision settings.

Under varied lighting conditions this sapphire performs with consistent sophistication. In bright natural daylight the stone presents its truest intense purple, with even color saturation and broad flashes of violet that contrast against deeper core zones, and moderate pleochroic shifts are observable when the stone is rotated, moving between richer violet and cooler bluish purple. Under warm incandescent or halogen illumination the gem takes on a slightly warmer aspect, the saturation appears fuller and the depth increases, producing a velvety, near regal tone. Cool white LED or fluorescent lighting enhances crispness and contrast, accentuating scintillation and revealing sharper facet reflections along the brilliant crown. Point source lighting and spotlights provoke strong scintillation and small, brilliant flashes from the mixed cut faceting, while diffuse ambient lighting emphasizes even color distribution and minimizes contrast, presenting a more uniform field of intense purple. In lower light levels the gem maintains presence, reading as a deep saturated purple rather than losing its character. For mounting considerations, open back or light enhancing settings will amplify brilliance, white metal will emphasize contrast and crispness, and warmer metals will deepen perceived hue, and the gem s proportions and polish are well suited to rings or pendants where both crown orientation and pavilion exposure are optimized to exploit the mixed brilliant facets.
