The rarest and most expensive moonstones will be colorless with a floating blue color or schiller that seems to hover above the stone. This phenomenon, termed adularescence, results from moonstone’s composition of orthoclase and albite feldspars arranged in layers. Light reflected from these layers produces interference effects and causes adularescence. If the layers are very thin, a blue schiller is seen; when they are thicker a white schiller is seen.
With sterling bezels and 9ct tops, this pair of stones is immaculate. It is incredibly rare to find such blue schiller examples! Originating from the Edwardian period, these component earrings are perfect summer/winter additions to any collection.
