oil-free emerald

Due to their nature, emeralds have many internal scratches and inclusions, so they are generally impregnated with a clarifying agent.
Oil-free emeralds are emeralds that do not require impregnation and are beautiful even when untreated, and are highly valued and rare.
Emerald is the birthstone of May.
