Mankiewicz, also owns a large collection of emerald jewellery that goes marvellously well with his green eyes.

They are apparent when we look at them with a jeweller's magnifying glass. The purer the emerald, the harder they are to find. On the other hand, the absence of defects or irregular patterns could mean that it is glass or crystal. Here is a series of tests that can help you recognize a real emerald.

The value of an emerald
The purer the emerald, the more valuable it is. Like a diamond, The emerald is evaluated according to 4 criteria; colour, clarity, cut (size) and carat. The more intense the colour, the higher the price will be. Generally, a bright, transparent emerald with a few visible inclusions will be more valuable than a fuzzy emerald with many small inclusions. Real emeralds are dichroic. They appear blue-green at one angle and slightly yellow-green at the other. The stronger the dichroism with two distinct colours, the better the emerald. Each emerald is processed in cedarwood oil to lessen the visual impact of microscopic icing on its surface. This does not in any way detract from its value.
