Emerald Gemstone Guide

Emerald Gemstone

Emerald colour and cut

Emeralds come from the mineral beryl and are a vibrant and valuable green gemstone that complement gold jewellery settings particularly well. First found in Egypt, near the red sea, four thousand years ago, they were treasured by Romans and worn by Cleopatra. They are now worn by Hollywood's elite actresses' and are seen as a particularly luxurious style of jewellery. Our Emerald jewellery at H.Samuel makes an excellent gift for special occasions, particularly the twentieth wedding anniversary or a birthday in May. Emerald is the traditional birthstone for May and it is considered extra lucky if you receive emerald jewellery during the birthstone month.

Emerald colour and cut

Emerald derives its beautiful vivid green colour from the presence of the minerals chromium and vanadium. Emeralds are oiled to strengthen and enhance their colour and to disguise cracks and hide flaws. The recognizable emerald cut, or step cut design which is also a popular diamond cut is designed without corners to reduce the risk of damage to the stone and minimise the loss of material. The clarity of the emerald gemstone needs to be flawless to the naked eye, emeralds are often filled with resin to make them appear flawless. Emeralds with few or no inclusions are so rare; they're more expensive than diamonds.

Caring for emerald

Emerald does not have a strong resistance to breakage and can be damaged easily. Emeralds are sometimes treated or filled with oil resins to fill or conceal any cracks or damages. This then improves the clarity of the emerald. When caring for your emerald jewellery use a small, soft brush and warm water. Where possible avoid exposure to heat as this may also cause the gemstone to expand and crack.

Sourcing emerald

Emeralds can be sourced in many areas of the world including Brazil, Zambia, Pakistan and Siberia. However there are three main mining areas in Columbia, Muzo Coscuez and Chivor. Due to emeralds rarity, there has been a method developed for producing emerald overgrowth from colourless beryl.
