Emeralds are green precious stones, being the premier gems in the beryl family of stone-rocks and the most valuable of all jewels on earth.

Geologically speaking, Colombian emeralds are the purest emeralds in the world because its deposits are the only ones on earth found in sedimentary host rocks rather than in igneous rocks.

An emerald is actually a beryllium stone that owes its special color to beryllium, chromium, and vanadium. All of which are chemical elements that are very scarce and are the reason for the color of an emerald.

A gem’s value depends upon its size, purity, color, and brilliance. Even when they are mined in the same area, each individual emerald has its own unique characteristic that sets it apart from the rest. Dark green is considered to be the most beautiful, scarce, and valuable color for emeralds.
