Long, parallel facets step down from a large flat table to the edge, like a staircase. Light moves across the stone in broad, clean flashes rather than sparkle, so its colour and clarity are easy to see.
A unique colour: a cool, metallic grey blue with a green undertone, in a bright oval with a brilliant crown. A collector's stone that is hard to match.
It comes with GIA report 5566582215, which identifies it as a tourmaline that contains copper and manganese. The report notes that the properties are not consistent with what the trade calls “paraíba tourmaline”, and that colour origin cannot currently be determined. We sell it as unheated. The report is included in the price.
