Emerald is the birthstone for the month of May. It is the world’s most popular green gem. It is the green variety of the mineral beryl. Emeralds range in color from slightly yellowish green, to pure green, to slightly bluish green. Pure green emeralds are the most popular and valuable.

Emerald can be a costly gem, and it often lacks the high level of clarity that many people desire. For that reason, lab-grown emeralds have become a popular option in birthstone jewelry. Lab-grown emeralds can be purchased at a small fraction of the cost of a natural emerald of similar size, color, and clarity. The buyer and the recipient of an emerald birthstone gift might be pleased with this option. Image copyright iStockphoto / mikheewnik.
