Black Opal Triplet Diamond Platinum Ballerina Setting Ring
Beautiful black opal triplet diamond platinum ring from the 1960s, showing an amazing array of colors from blue, green, orange with flashes of red. A opal triplet is a finely cut and polished piece of black opal which is layered between 2 pieces of cut and polished clear quartz. Opals consist mainly water and are very fragile so the quartz protects the opal from drying out ( crazing ) and chipping. The opal is surrounded by a hallow 20 bright and white tapered baguette cut diamonds and flanked by 2 marquis and one square cut diamond on either side. The ring size is now 5.75 and can be sized.
