What a great ring. The stone is called a Enami Mystic Quartz. Very pretty and distinctive color and the setting is perfect for all lighting and a distinctive band design. This is a unique stone and don't when I'll see it again. Your band is set in Stainless Steel. You have 2.40 ctw. See pictures to see the stone and the lovely band design.❄❄❄❄❄❄
