May Birthstone: The Emerald

Emerald’s Color

Perhaps you recall The Emerald City in “The Wizard of Oz,” named for the vibrant, scintillating greens of this popular gem.

Emeralds can range in color from light green with blue or yellow tones to deep, rich green. The finest emeralds have a deep green color, sometimes touched with a hint of blue and offering translucence, depth, and clarity. The green color comes from impurities of chromium, vanadium, or a combination of both. Iron will also affect the color, creating bluish tones.

Known for its inclusions, which are foreign materials trapped within the gem, emeralds are a unique stone. Some say that under a microscope, the inclusions can look like mossy plant-life. The inclusions can also be an indication of a gem’s origin.

The emerald is a variety of the mineral beryl, which forms with six sides. March’s birthstone, aquamarine, is also a type of beryl.
