1.83 Ct. Pinkish Purple Sapphire from Tanzania

This 1.83 carat oval pinkish purple sapphire from Tanzania is cut to precise dimensions of 7.68 by 5.92 by 4.86 millimeters, it is faceted in a mixed brilliant cut to marry the depth and color saturation of an oval outline with the dynamic light return associated with brilliant faceting, the mixed brilliant arrangement concentrates pavilion facets to optimize internal reflection while using a faceted crown that disperses light into lively scintillation, the excellent polish and crisp facet junctions further enhance contrast and ensure each facet plane returns light with clarity and minimal disturbance, clarity is graded as very slightly included evaluated at eye level, these minor inclusions are non disfiguring, they often act to subtly break light at micro levels and add to the stone s personality without compromising transparency or brilliance, the color intensity is vivid and the sapphire is untreated, an unenhanced natural color from Tanzania which collectors and connoisseurs prize for authenticity and stability.

Technically the mixed brilliant cut in an oval silhouette is chosen to balance two competing optical goals, first it preserves and concentrates the rare pinkish purple hue by maintaining sufficient depth to avoid windowing, second it enhances scintillation and overall brightness by employing a pavilion geometry that maximizes total internal reflection for sapphire s refractive index, compared to more common gemstones such as standard blue sapphires and many commercial spinels, this sapphire exhibits a richer hue driven brilliance rather than sheer white flash, compared to diamond, sapphire has lower dispersion and a lower refractive index so it does not produce the same spectral fire, however this sapphire s vivid saturation and expertly executed facet pattern produce a different and highly desirable type of brilliance, one defined by deep luminous color, pinpoint scintillation, and a velvety glow that emphasizes tone and saturation rather than rainbow flashes.

At The Natural Sapphire Company we emphasize craftsmanship and provenance, this stone s combination of mixed brilliant faceting, excellent polish, vivid natural color and very slightly included clarity offers a rare optical signature, the optic effect is immediate when viewed face up, color concentrates toward the center with lively scintillation along the crown facets, the untreated Tanzanian origin enhances desirability for collectors who value natural coloration, whether set in a refined bespoke piece or kept as a collectible, this 1.83 carat pinkish purple sapphire delivers technical excellence and a unique visual performance that stands apart from more conventionally brilliant gems.
