May - Emerald

The earliest emeralds were found in Egypt almost 4,000 years ago and were highly prized by Cleopatra. Emeralds, symbolizing youth, vitality, nature and rebirth, are also believed by some to improve memory or help a person to become an eloquent speaker.

Varieties, Qualities & Origins
E
merald is the most rare variety of the gem species beryl that includes aquamarine (blue) and morganite (pink). The most rare and valuable emeralds are medium tone, the most vivid possible, slightly bluish-green in hue, and rivaled only by ruby in value.

Gemstone Enhancements
F
orming under very volatile conditions, even fine quality emeralds frequently have internal inclusions and fissures. These are not considered negative, as long as they do not affect the appearance or durability of the gem. Emeralds with fissures reaching the surface are often oiled to improve their appearance. This enhancement includes oils such as linseed, cedarwood and Canada balsam to sophisticated resins, polymers and sealers.
