| Natural Emerald Overview: | |
 |
Emerald is a form of
Beryl and gets its characteristic emerald green color from traces
of chromium (and possibly vanadium) in the crystal matrix. Emeralds
of excellent quality that exceed a carat frequently are valued above
diamonds. Inclusions caused by calcite deposits (jardin) are typical in emeralds and color saturation and hue are a bigger factor in determining the value of an Emerald. Colombia enjoys the reputation of supplying the finest in Emeralds but excellent quality gemstones are also produced in Brazil and Zambia. Most Emeralds are oil-treated when they are cut to reduce the likelihood of fracture. Some care must be taken in the setting of Emeralds in jewelry and the wearing to reduce surface impacts. The majority of our Emeralds are Colombian, many from the renowned Muzo Mine. |
| Legend and Lore: | |
| Emeralds have been treasured for thousands
of years. The infatuation with Emeralds dates back to ancient Egypt
and Rome. It is said that Cleopatra was always adorned in Emeralds
and that this was her most treasured jewelry. Emerald is the anniversary gemstone for the twentieth year of marriage, and symbolizes love and success. |
