Beautiful antique blue enamel ring centering an approx. 0.55ct cushion old mine cut, quality is approx. M-N si2-i1 but it's a beautiful natural diamond and looks eye clean. With rare blue enamel detail with very little loss. 

The ring is made of 18k yellow gold and fits a finger size 6.75. would not recommend sizing this piece unless to make it smaller with balls or sizing band on the inside. Are you it's Cinderella? 🤌❤️
