The Patricia Emerald is a large and superbly colored specimen. At 632 carats, the dihexagonal, or twelve-sided, crystal is considered one of the great emeralds in the world. Found in Colombia in 1920, it was named after the mine owner's daughter.
The flaws in this emerald are normal but compromise the hard gem's durability. This specimen is one of the very few large emeralds that have been preserved uncut. Today, Colombia is still the world's major source of emeralds.
