No Reserve!! Rainbow Matrix Opal- Andamooka- 53Frogs

Item Information

SKU RG66211
Dimensions (mm) 25 x 15 x 6mm
Weight (carats) 15 carats
  • Cabochon

There are a few different types of matrix opal found in Andamooka, and this Rainbow matrix is the most porous of them all. It is sometimes called "Concrete" due to the conglomerate embedded within the quartzite matrix and the general resemblance to building concrete in its untreated state. The treatment process darkens the quartzite base so the Opal can be seen more clearly, and the Resin creates an even finished surface.



Origin: ANDAMOOKA Australia

Number of pieces: 1
