|The Very Highest Quality Moonstone Information...|
Probably the most famous moonstone of all was not a moonstone but a diamond. In the well-known classic book "The Moonstone" by Wilkie Collins, a large diamond was stolen from an Indian shrine, and a retired policeman is hired as a private detective to investigate a murder and robbery. Wilkie Collins is recognised as the inventor of the English detective novel, and was a friend and colleague of Charles Dickens. Although "The Moonstone" was written in 1868, it remains to this day a masterpiece of English literature. The book is clearly based on a number of stories about famous diamonds which have disappeared and reappeared over the centuries.
Moonstone contains a number of typical inclusions which appear to be stress cracks. These give the appearance of centipede type insects, Chinese "aeroplanes" looking like characters from Chinese writing, negative cavities looking like rectangular crystals, and needle-like shapes. If present in large numbers, the needle shaped inclusions can cause a cat's eye chatoyancy effect.
The most desirable colour of moonstone is blue, but it also occurs in grey, white, pink, green and brown.
