The fine silver rope border around the frame of this ring really takes it to the next level, as it sets upon its wide wrap-around silver band – that also allows for some size adjustability! Royston turquoise is a well-known type of turquoise found in the Royston mining district in Nevada, USA. It is highly valued for its beautiful colors, which often include shades of green, blue, and brown. Royston turquoise can have a unique matrix pattern, which adds to its visual appeal and individuality. The center stone measures around 3/4″ x 1/2″. The ring face measures around 1″ x 7/8″. Signed by Navajo artist, Leon Martinez. The ring size is around 7. Make Us an Offer! All Other Museum Items. If the item breaks we will repair it for FREE.
