7.05 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This transparent 7.05 carat emerald cut bi color parti sapphire measures 11.74 by 8.78 by 6.49 millimeters, and presents a faceted cutting style with an emerald cut profile, clarity graded as very very slightly included at eye level, and a medium color intensity with excellent polish. Originating from Ceylon, Sri Lanka, and heat treated as a standard enhancement, this stone displays the structural integrity and optical properties expected from well cut Sri Lankan sapphires. The stepped facets of the emerald cut produce broad, parallel flashes that emphasize the stone's color zones, and the very very slight inclusions are minor at face up view, contributing minimal distraction to light return and overall transparency.

The sapphire’s vibrant color will stand out in any jewelry setting, due to the combination of medium color intensity, excellent polish, and the emerald cut’s capacity to exhibit color separation with clarity. The bi color parti characteristic yields a dynamic interaction between lighter and deeper blue zones, allowing the stone to read differently under varied lighting and viewing angles, which enhances visual interest without compromising uniformity when set. In open settings that allow light to enter the pavilion freely, the stone’s transparency and faceting produce pronounced color saturation and depth, while more enclosed bezel or channel settings moderate contrast and can create a subtler, more uniform appearance. The overall polish and faceting ensure consistent reflectance across the crown and pavilion surfaces, optimizing brilliance and the distinct banding typical of a parti sapphire. The Natural Sapphire Company presents this gem with full technical disclosure, allowing designers and clients to evaluate how the stone’s dimensions, cut proportions, and optical behavior will interact with metal choice and mounting style. For applications where the objective is pronounced color presence, the emerald cut bi color parti sapphire will deliver a controlled yet vivid visual statement, adaptable to rings, pendants, and other bespoke pieces that prioritize both color complexity and refined craftsmanship.
