Black Opal Ring Buying Guide - Value Factors, Color Play & Authentication Tips
Larger opals are generally rarer than smaller ones, and this is why if you are eyeing a Black Opal ring with a larger stone, it would be priced higher than the one having a smaller Black Opal. Also, certain shapes, like oval or cushion cuts maximize the display of play of colors present in opals, thereby making the stone more attractive and more expensive. So, if your ring features such shapes, or if the Black Opal present in your ring is bigger, then your Black Opal ring will be priced higher.
