Gemology Information
Emerald is the green member of the beryl mineral family (which also includes
Aquamarines). Its fine intense green coloring is due to a trace of chromium
or vanadium replacing the aluminum in the beryl structure. Because of the
nature of this replacement, almost no Emeralds with intense color are free
from inclusions. These inclusions are acceptable as long as they do not
take away from the durability or beauty of the stone.
Since natural Emerald can contain liquid and gas inclusions, jewelers use
care as this gemstone needs to be kept away from any high heat -- Emeralds
should not be cleaned in an ultrasonic machine or steam cleaned.
The name Emerald is from the Greek "smaragdos" (green), through
the Latin "smaragdus" to Middle English "esmeralde."
