Emerald General Information
Medium to dark green beryl which derives its colour from chromium and
vanadium.
Clean your Emerald with a soft, dry cloth. Avoid sudden temperature
changes, household chemicals and ultrasonic jewellery cleaners.
Emerald is often treated with oil to fill fissures and fractures that
are characteristic of emerald. Hence, You should never clean an emerald
in an ultrasonic cleaner because this oil could be removed or damaged,
making the fissures more visible. In addition, do not clean emerald in
hot soapy water since it too can remove this oil.
Emerald is often irradiated for clarity.
Reputable dealers will not use the following misleading terms.
However, for your protection, I am listing them here:
"African emerald" is really green fluorite from South-West
Africa
"Cape Emerald" is really prehnite found in South Africa (not
to be confused with true emerald from South Africa).
"Evening Emerald" is really peridot.
"Indian emerald" is really green-dyed quartz.
"Medina Emerald" and "Spanish Emerald" are really
green glass.
"Mt. Saint Helens Emerald" is green glass that is man made
by fusing volcanic ash.
"Scientific Emerald" is really synthetic stones or paste.

More Emerald Lore
The Romans loved emeralds because, as ancient scholar Pliny said,
"nothing greens greener." Pliny said that emerald was the only
gem which delighted the eye without fatiguing it. He said his eyes were
restored when gazing at emerald. Emperor Nero wore emerald sunglasses to
watch the gladiators.
The Moguls of India, including Shah Jahan, the builder of the Taj
Mahal, loved emeralds so much they inscribed them with sacred text and
wore them as talismans. Some of these sacred stones, called Mogul
emeralds, can still be seen in museums and collections today. For
example, one talismanic emerald is deep green and weighs 78 carats.
Around the edge in Persian runs the inscription:
"He who possesses this charm shall enjoy the special protection
of God."
According to legend, emeralds strengthen the owner's memory, quicken
the intelligence and assist in predicting the future.
Emerald is the US State Gemstone of North Carolina.
Emerald is said to be the Spring Gemstone of
the Season.
