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
Emerald 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
Forming 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.
