A diamond is the symbol of beauty, wealth and permanence for almost everybody. Diamonds are not only the most valued precious stones with a unique lustre (and for these reasons very expensive) but also the hardest existing stone on the Earth.

As we know, not without reason Marilyn Monroe sang: "Diamonds are a girl's best friend...". With absolute certainty, diamonds are the most durable...


Origin of the word


The name of this mineral comes from the Greek word adamas - unconquered.






The symbol of power and audacity. A diamond gives powers of concentration, brings joy and happiness, luck in love and bolsters courage. A diamond is considered a sacred stone and is regarded as a symbol of purity and peace. It should be shielded from the vision of bad people. If it "experiences" evil, its brightness becomes dim.


A diamond protects its owner and deflects bad thoughts that could torment him or her. It also helps to restore peace of mind. Its brightness makes a person healthy and happy. A diamond gained in a dishonest way brings bad luck.    


It is a birthstone for people born under Aries, Leo, Libra and Capricorn.
