Calcite forms with several different colors depending on the chemical impurities present as the crystal is growing. Clear, translucent Calcite, also known as 'Iceland Spar', is double refractive, which means that if you hold it like a magnifying glass over a line of text you should see a double image of the text through the stone. Iceland Spar is believed to have been used by Norse seafarers as a navigation aid.

Calcite is said to open doors, create unexpected opportunities and shed light on problems, helping you to find inspired solutions even when the situation seems hopeless. It is a powerful crystal to use in magic to gain good things, such as love, contentment, success, wealth, friendship and security.

Golden Calcite is said to help depression, lessen grief and release emotions and past traumas that are holding you back from being the person you would like to be. It is a good stone to work with if you are going through the grieving process, and is believed to help you work through your pain to find acceptance and grace.

Green Calcite is believed to be a powerful healing stone and is especially good for the stomach and digestive system. It is also a good stone to work with if you want to increase the good things in life or encourage fertility, growth and success.

Orange Calcite encourages creativity and spontanaiety. It can help you to connect with your inner child and rediscover the sense of adventure and wonder that so many people lose as they grow older. Working with this crystal helps you learn to enjoy life without inhibitions and to overcome the fear of criticism that might stop you from creating purely for the joy of creation.

Calcite is a Mercurial crystal and all colors are said to release powerful psychic energies. It is an excellent stone to keep in a room where you will be meditating or working magic. If you work with a group a piece of Calcite can help to focus and harmonize the individual energies to increase the available power and really get results. It seems to work particularly well for groups of volunteers who are planning work for the greater good and focusing on helping other people.
