Alopecia areata is a disease that attacks your hair follicles (the part of your skin that makes hair). In most cases, hair falls out in small, round patches about the size of a quarter. This causes only a few bare patches. Some people may lose more hair. In only a few people, the disease causes total loss of hair on the head or loss of all body hair.
Turquoise is a blue-green mineral, a copper aluminum phosphate, valued for its rarity and unique hue, and widely used as an ornamental stone. Popular in the 16th century to adorn places of worship in Turkey, it was eventually traded in Turkish bazaars and brought to Europe by merchants and travelers.
It is the natural variations in turquoise that make it appealing. The color of turquoise in American Indian jewelry ranges from brownish green to bright blue. Found in veins sandwiched in between layers of mother rock, the turquoise can show some of the influence of the mother rock in its matrix or veining.
