1.29 Ct. Violetish Blue Tanzanite from Tanzania

This listing describes a transparent 1.29 carat oval violetish blue tanzanite measuring 8.35 by 5.67 by 4.14 mm, cut in a mixed brilliant style. The mixed brilliant cut combines a faceted crown with a calibrated pavilion to optimize both light return and scintillation. Clarity is graded as very slightly included when evaluated at eye level, presenting excellent transparency that allows light to pass through the gem with minimal obstruction. Color intensity is classified as intense, and the gem displays a clean, saturated violetish blue tone. The surface finish is an excellent polish, and there has been no enhancement to the stone. The origin is Tanzania, and this specimen is presented by The Natural Gemstone Company.

The exceptional sparkle of this tanzanite is the result of a number of structural and cutting considerations working together. The mineral structure of tanzanite produces notable pleochroism, so the stone exhibits varying blue and violet tones when viewed from different angles, and that changing color contributes to a dynamic play of light. The mixed brilliant cut on this oval form creates a precise arrangement of facets that both refract and reflect incoming light, producing strong internal reflections and rapid scintillation across the table. The combination of well proportioned crown and pavilion facets directs light back to the observer, while accurate facet junctions and an excellent polish minimize light leakage. The gem s intense color provides contrast between bright flashes and deeper color zones, which amplifies perceived brilliance. The clarity grade indicates only very minor inclusions that do not interfere with light performance at normal viewing distance, allowing the structural optical effects to remain the dominant visual characteristic.

This tanzanite is suitable for center stone settings where facet geometry and light exposure can be maximized, such as open prong or bezel designs that preserve the stone s ability to interact with light. Because there has been no enhancement, the color is completely natural, and standard gem care practices are recommended to maintain polish and luster.
