Turquoise is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminum. It has been prized as a gem and ornamental stone for thousands of years owing to its unique hue. Color is as variable as the mineral’s other properties, ranging from white to a powder blue to a sky blue, and from a blue-green to a yellowish green depending on other elements.

Due to the aberrant nature of minerals, each piece of gem/mineral is unique.

From an inspiring earth science lecture on minerals, the jewelry collection Mineralogy began. It only seemed fitting that the name was the definition—the study of minerals—since the design process is centered around that study. Made in Chicago, IL.
