Lapis lazuli is regarded by many people as the stone of friendship and truth. The blue stone is said to encourage harmony in relationships. It help its wearer to be authentic and give his or her opinion openly.
The prices of this gemstone depend on the intensity of its colour. The most popular is an intense, deep blue colour. Fine crystals of pyrites which shimmer in gold will increase the value of the gemstone, whilst a restless, rough grain will reduce it.
I also have a bracelet of lapis lazuli.
