What are the emeralds?

emeralds are highly valued, dark green gems and derive their color from chrome. They are traditional May stone, although those born in May can require deep pockets to get quality emerald. The nature of their formation leads to a larger number of shortcomings in emeralds than in some other gems. Therefore, the relatively unlimited gem is rare and expensive.

Although emeralds have a hardness of 7.5 on the scale Mohs, inclusion in stones can cause easy breaking. For this reason, commercial emeralds are often coated with resin to prevent damage to the stone. All emeralds have certain shortcomings because they are formed in three phases. Errors are referred to as Jardins , French for the garden, suggesting that shortcomings naturally bloomed from formation processes.

Small, very defective emerald chips are generally cheap ornaments in jewelry. A large number of shortcomings affect the luminous intensity of stone and small chips may look more like nephrites than a clear gem. Larger emeralds with fewer Jardins are really rare and can therefore be very expensive. Two carat stone of the highest quality can cost up to $ 15,000.
