Royston turquoise is found in a remote part of Nevada and is considered the classic American turquoise! The brown matrix and softer greenish blue tone creates a softer contrast and is beautiful set in silver or white gold.
This stone has a single strip of turquoise within the host matrix and is called boulder turquoise, or sometimes this specific pattern is called "Ribbon Turquoise".
