What To Look For

Color Is The Most Important Quality Factor For Emerald

The most desirable emerald colors are bluish green to pure green, with vivid color saturation and tone that’s not too dark. The most-prized emeralds are highly transparent. Their color is evenly distributed, with no eye-visible color zoning.

Clarity Refers To The Inclusions
Emeralds typically contain inclusions that are visible to the unaided eye. Because of this, trade members and some consumers understand and accept the presence of inclusions in emeralds. Eye-clean emeralds are especially valuable because they’re so rare.
Cut Is One Of The Most Important Factors In Appearance

The most popular cut is the emerald shape due to the original shape of the crystals. Well cut stones maximize the beauty of the color while minimizing the impact of fissures, and creating a bright, lively stone.

Carat Weight Allows For Precise Measurements
Fashioned emeralds come in a wide range of sizes. There are emeralds in museums and private collections that weigh hundreds of carats. At the other extreme are tiny emeralds that weigh fractions of a carat. Quality-for-quality, the price of emerald can rise dramatically as the size increases.
