Sleeping Beauty turquoise - named for the Sleeping Beauty mine in Globe, Arizona - is among the most prized turquoise varieties in the world: its defining characteristic is an exceptionally even, robin's-egg blue color without the matrix veining that most turquoise displays. The uniformly pure blue that Sleeping Beauty produces is irreplaceable in turquoise collecting, and its mine closure in 2012 has made genuine Sleeping Beauty increasingly rare and desirable. A set of three graduating stud sizes in sterling silver provides the everyday wearability of the stud format across different occasions and different earring preferences - small for second piercings, medium for daily wear, larger for when the color statement should be clear.
