Emerald
Emeralds are the green variety of the mineral beryl and are the most famous and favoured of all the worlds green gemstone. Its beautiful green color, combined with durability and rarity, also make Emeralds one of the most valuable gemstones. Emeralds are notorious for their flaws. Flawless stones are very uncommon, and are noted for their great value. Some people actually prefer an emerald with very minute flaws over a flawless emerald, as this proves authenticity of the stone.

Emerald Cut
The “Emerald Cut” (used for many gemstones) is a step cut that has had the corners removed. This cut produces the optimum size of gem from well formed crystals and, as Emerald is a brittle stone, reduces the risk of damage during setting and wearing.
Caring for Emeralds
Many Emeralds are treated with oil resins to fill any cracks and fissures. This hides the fractures, enhancing the appearance by improving clarity and colour. Because of this, you should never clean emeralds in an ultrasonic cleaning machine as it will remove the oil, replacing it with dirty cleaning fluid which dries in its place and spoils the stone.
To clean an Emerald or Emerald jewellery, use a soft old toothbrush or piece of cloth dipped in luke warm water. Avoid soaking Emerald jewellery in hot, warm or cold water. The water may seep into the treated fissures and dilute or dissolve the fillers. Exposing the emeralds to heat may cause the fissures to expand and make your Emerald very fragile.
