Pink or peach-colored quartz is called rose quartz, and is mainly used in decorative carvings. Its color is thought to be due to the presence of small amounts of titanium. Crystals of rose quartz are very rare. Transparent material is uncommon; it is usually cloudy or cracked, partly because it is so brittle. There are several gems that are believed to be good for love, including rose quartz, which is known to be the stone of unconditional love. Its calming energy is thought to help give one a sense of inner peace and love for one's self. Rose quartz also encourages sensitivity and compassion, even helping us to build trust in others, all attributes that are harmonious with the act of falling in love. Essentially, rose quartz puts you in a state of mind that allows you to receive love. If you are suffering from lost or unrequited love it will help to comfort you; if you have been betrayed in love it will help bring back faith and trust, as well as a sense of self-worth and self-esteem; if you have simply never been in love, it will open up all the possibilities of falling in love. Your marriage can have more sparkle and fire when you keep a rose quartz under your pillow. You will look younger too. When worn in jewelry the wearer feels a sense of self-worth.
