25mm aventurine heart from Australia, heart that is cut entirely by hand.

The heart is a very old symbol of love used by everyone around the world. Traditionally, the heart has been chosen in several cultures as the seat of love and feeling. It is not entirely clear why the heart was chosen as a love symbol. Perhaps because the heart is automatically related to the (feeling) life and without the heart (read love) no life is possible. The heartbeat is partly influenced by feelings; so our hearts beat faster when in love. The heart likes to be loved. The heart needs love. It has even been claimed that love extends life expectancy, while loneliness is counterproductive. Everyone knows the phrase, "He died of a broken heart."

Aventurine or aventurine is a green to reddish-brown colored variety of the mineral quartz. Usually this gemstone comes in the green and cut variant. Aventurine has a hardness of 7 and is found in Russia in the Urals and China. Aventurine, like many other varieties of quartz (for example, amethyst and rose quartz) is cut so that it can be used as jewelry. The chemical composition of aventurine is SiO2 KAl2 (OH, F) 2 / AlSi3O10 Cr. The Ancient Greeks sewed aventurine into a warrior's clothing to maintain his courage, ambition and optimism.
