2.63 ct Green Emerald - Pear

At 2.63 carats, this emerald from Zambia carries its green color through a pear cut, measuring 12.2 x 7.51 x 4.97 mm.

Emerald is the green beryl, colored by chromium, and nearly always carries the internal garden of inclusions that proves it grew in the earth rather than a lab. Zambian emerald forms with more iron in the chemistry, so the green cools a step toward blue and the crystal often grows a grade cleaner; Kafubu is the modern counterweight to Colombia. Clarity is finished with the oiling the trade has long used for this family, disclosed here as on every listing.
