Bi-color Sapphire 10.216ct

10.24×14.14×6.67mm

Origin: Nigeria

Octagon

Piachan's work

Comes with a sorting report (EGL simple identification report)

A 10ct+ Nigerian bi-color sapphire, featuring vibrant lemon yellow with deep, silky blue.

It is a masterpiece finished with a neat octagon shape and a step cut.

Some of you may remember our previous introduction, but this museum-quality gem has returned after a refinement.

This time, detailed adjustments have been made, further enhancing the polished flow of light.

In a vivid and clear lemon yellow, deep blue gathers in the corners, creating green at the boundary and expressing a rich bi-color through internal reflection.

The color gradation shifting from blue to green and then to yellow is a major charm unique to this stone.

When light hits the blue/green color pooling, silky lines emerge in a bluish-white, giving a sense of sapphire's depth and texture.

Fine inclusions are visible throughout, but they do not detract from the impression of the piece, and the yellow zone, in particular, has very high transparency, maintaining a clear brilliance.

Furthermore, unique inclusions are scattered, resembling pencil scribbles or tree branches, creating a scene like a jungle captured within.

Several growth lines visible in the center tell the story of the powerful earth where this crystal grew.

With a solid thickness, the proportion is very good, and the balance is excellent.

The linear reflection unique to the step cut makes the bi-color sparkle sharply traverse the entire stone.

An interesting point is that the yellow zone gently fluoresces red when exposed to UV light.

Please enjoy this masterpiece, which boasts an overwhelming presence of over 10ct and powerful yet beautiful colors, firsthand.
