Truly a unique and rare collectible find! What is "Boulder" turquoise and where is the Boulder Turquoise mine? From the internet, "The most common feature of Boulder Turquoise jewelry is the beautiful vein-like structure of blue coursing through the pale white coloration on the main stone. For this reason, it's also called Ribbon Turquoise. The pattern is reminiscent of a free-flowing river or a cascading ribbon; this stone makes a lasting impression on anyone that sees it. The reason for color variation in this rare type of stone is from the small cracks in the rock. From there, the turquoise changes with mineral content. Each mine containing this beautiful stone has its own unique ecosystem with different minerals seeping into the source stone over thousands of years. This is why the stone varies from a beautiful eggshell white to a darker brown, but usually has striking lines of traditional blue throughout. This type of stone is found in the famous Royston Mines in Nevada. Unlike most other turquoise types that are identified by their mine origins (e.g. Kingman Turquoise comes from the Kingman Mine), the uniqueness of the turquoise patterns that map through beautiful and varied brown stones is what gives Boulder Turquoise jewelry its distinctive name and flair."Please check out my other Ebay listings for more amazing finds!
