Chosing a design for your opal jewellery September 22, 2021March 15, 2013 by Justin Thomas When choosing your jewellery design for your opal you should use a simplistic design as it can really bring out the color play in your opal. If you put to much “bling” around it, the piece can get too busy, As opal has so much color play going on in it there is no need for more. I see so many people put clusters of diamonds around an opal and this is fine but if you want to show off the stunning opal that you love. Keep it simple.
