Display boxes do not come with items.Turquoise comes in all shades of blue, to blue-green, with a possible shading towards brown-veined greens. 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. The matrix colors range from blue to golden brown to black and sometimes with golden flecks (sometimes called "fools gold" or iron pirite) which is very desirable. The more blue, the higher the copper content. The more green, the higher the iron content. Sometimes turquoise is cut so that it takes some of the mother rock with it. This is referred to as " Boulder Turquoise " and it is very popular as it shows great contrast between the turquoise and the surrounding rock with which it formed.
