_ The diamond has been one of the most coveted gems in history. Uncut diamonds adorned the suits of armor of the great knights. Cut diamonds have adorned crowns of kings and queens throughout the ages. Today the diamond is internationally recognized as a symbol of love and betrothal and is the recipient of increasing interest as a source of investment.
The diamond has been credited with many magical powers. At one time it was considered the emblem of fearlessness and invincibility. It was believed that the mere possession of a diamond would endow the wearer with superior strength, bravery, and courage. It is also believed to drive away the devil and all spirits of the night.
In the 1500's it was believed to enhance the love of a husband for his wife. In the Talmud a gem believed to be a diamond, from its description, was worn by the high rabbi and served to prove innocence or guilt. If the accused was guilty, the stone grew dim, if innocent, the stone shone more brilliantly than ever.
The Hindus classed diamonds according to four castes. The Brahmin diamond, colorless, gave power, friends, riches and good luck. The Kshatriya diamond, brown/champagne, prevented old age. The Vaisya, color of the "kodali flower", brought success, and the Sudra, a diamond with the sheen of a polished blade-probably gray or black-brought all types of good fortune. Red and yellow diamonds were exclusively royal gems, for kings alone.
Diamonds have been associated with almost everything from preventing sleepwalking to producing invincibility and spiritual ecstasy. Even sexual power has been strongly attributed to the diamond. There is one catch to all the associated powers; one must find the diamond "naturally" in order to experience its magic, for it loses its power if acquired by purchase. However, when offered as a pledge of love or friendship, its powers may return, hence the use in engagement rings given in love.
Diamond have been found to occur naturally in almost every color and shade, blue, red, green, yellow, lavender, pink, gunmetal blue, coffee brown, and black. The color may be intense or very pale. These are very expensive because they are very rare, some more than others. The most common fancy colors are shades of yellow, very intense, bright yellow called "canary", orange and brown. Among the most rare and most valuable are the reds and blues, and the least valuable are the black diamond.
