If you like more of a green tinge in your turquoise then Royston would probably be your choice
This ring makes a beautiful statement! 9 stones and each is approx. 5/8" by 1/2"
A deep sea green coloring accented with brown matrix could only be Royston turquoise. There is no other turquoise that has quite the color combinations that Royston turquoise does. This ring really showcases those colors!
