People have admired emerald’s green for thousands of years. There are other green gems, like tourmaline and peridot, but emerald is the one that’s always associated with the lushest landscapes and the richest greens. Today, most gem dealers consider emerald to be the world’s premier green stone.

Emerald has many special qualities; however, colored stone professionals generally agree that color is the most important factor setting emerald’s value. The most desirable emerald colors are bluish green to green, with strong to vivid saturation and medium to medium-dark tone. Slight differences in hue, tone, and saturation can make a great difference in emerald value when other factors are equal. To understand the difference that slight variations in color can make, imagine two 1-ct. emeralds, both of the same high clarity. The first is very slightly bluish green, with strong to vivid saturation. The second differs only in that its saturation is medium strong. According to emerald price guides, the saturation difference of the second emerald can drop its per-ct value by half—almost a thousand dollars. A similar comparison between emeralds that weigh several cts would result in a difference in value of thousands of dollars.


Emeralds typically have inclusions that are visible to the unaided eye. Most of trade members and some consumers understand and accept the presence of inclusions in emeralds. As the matter of facts that almost all emeralds contain inclusions, it’s not a good idea to ignore them in any buying or selling situation. Gemologists and other trade members generally classify emeralds as being lightly, moderately, or heavily included. Some inclusions commonly found in emeralds are crystals, fractures, needles, fingerprints, growth tubes, liquid inclusions, and two- or three-phase inclusions. However, fractures and liquid inclusions are amongst the most common inclusions found in emeralds.
