1.23 Old European OP, I1 GIA

Provenance: From a post-consumer jewelry piece, purchased loose.

Now this is a work of art! Closely examine how the cutter perfectly calibrates the 'mirrors' of this wonky (early) Old European so that it masks completely its bodycolor face up. That grandiose of a culet plays an important role too, achieving that oh so good: Kozibe effect. This light play most likely also intended to hide the mid-contrast of the feather in the material.
