Very nice ring stone.
We are pleased to present you solid matrix opal from the Andamooka, Australia. Such opals are becoming increasingly rare, as only a few miners work at Andamooka opal fields now days. We buy rough material directly from miners at the fields. We are processing matrix opals by ourselves, including cutting, cabbing, carbonization treatment and final polishing. Each matrix opal is subjected to multistage polishing on diamond wheels. The polishing of one matrix opal takes several times longer than polishing black or crystal opal. Matrix opals are very stable.
Solid Matrix Opals are worth more than other types of matrix opals, such as the Concrete and Sandstone Matrix. The picture shows the difference in the structure of these types of opals.
All photos were taken with a Pentax KP camera and a 35mm macro lens or an Olympus EM1 camera with a 30mm lens.
As a lighting, LED lamps with a warm spectrum are used. In order for the colors to be displayed correctly, the cameras are adjusted using a color map ColorChecker Passport.
