Color
Turquoise encompasses a wide range of deep blues and greens, from very pale and light to deep and dark. American turquoise in particular tends to be mottled with inclusions of pyrite and other minerals, giving it a more unique look.
Geographic Sources
Turquoise is readily found in Afghanistan, Australia, the Middle East and America.
Rarity
Lower quality turquoise is bountiful, but higher quality is more difficult to find and thus, quite expensive.
Physical and Emotional Uses
Turquoise is linked to powerful personal protection. It enables communication from the highest source of love, eases feelings of negativity and low self-esteem, and supports and energizes the thymus chakra to boost immunity.
Healing Properties
Place over the heart, throat or thymus area to ease breathing and allow emotional expression.
Personal Use
Wear over the upper chest for personal and psychic protection.
Because of its popularity, combined with the fact that it is difficult to find high quality turquoise, other stones are often dyed to mimic turquoise for use in jewelry making. Additionally, turquoise itself is often dyed and stabilized to make it more appealing. If you are shopping for turquoise jewelry, be sure to ask if the turquoise you are looking at is natural.
