The word Diamond is derived from the Greek "adamas" (unconquerable). It is believed that Diamond is the symbol of an engagement ring. Diamond has strong hardness from scratching, so it is also connected to image of "Eternal Love".

In ancient times, the Diamond was men's Gemstone. It was believed that a man's hand and foot became strong when the Diamond was put on left side. There was also legend, when fighting with an enemy, diamond obtained a victory for its wearer. When did women come to put on Diamonds? Once upon a time, Diamond was only mined in India, it was the object of envy for the Royal Families of Europe. It is also a natural result that the Diamond was gradually connected with the symbol of financial ability and power, and the Royal Families were attached. Especially, between France court and Diamond's connection was deep.

Pioneers' emotional strength is admired anytime. It was first time when a French woman is wore the Diamonds which was men's symbol till then. The woman's name was Agnes. In order to pull King Charles VII's mind, she borrowed some Diamonds from the knights, and used the Diamonds as her original designed necklace. Her demonstration was succeeded in catching a king's heart splendidly. Although Charles VII was generally known as a king helped by Joan of Arc, Agnes must also have been reflected in the brave woman for him. This will change with a cause and Agnes will receive a king's love.

This simulative occurrence woke the women of the France court of those days, competition that vies in beauty to the symbol of wealth and authority was added from the 15th century to the 18th century, and the history of the scramble of a Diamond was developed. However, for people, the Diamond was far beyond reach. Because, the clergymen and the porphyrogenite monopolized the Diamond as a symbol of power. Rescinded a ban of gemstone at the French Revolution (1789).

The Jewish who immigrated to Poland around then proposed the custom of also presenting ordinary women with each other's engagement ring, as porphyrogenite's daughters were presented with the engagement ring. Diamonds mines were discovered besides India: in Brazil around 1720, in South Africa around 1870, in Australia and Canada after 1980. Discovery of these mines animated the jewelry industry and the Diamond became the symbol of an engagement ring completely.
