Emerald has many special qualities, but colored stone professionals generally agree that emeralds are most of all, about color. Emerald has been the standard of green among colored stones for thousands of years.
The most desirable emerald colors are blueish green to green, with strong to vivid saturation, and medium to medium-dark tone. The most prized emeralds are highly transparent.
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.
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.
Emeralds are relatively hard and suitable for daily wear. Even if they are oil treated, care should be used in storage to avoid chips and scratches; separate it from other jewels in it's own bag or box. To clean, use warm soapy water to gently clean them regularly. Avoid ultrasonic cleaners. After cleansing wipe with a clean, dry, soft cloth.
