This is a superb agate specimen with extraordinary colour zoning from the basaltic vacuoles of the Parana Traps, displaying coral orange outer zone and layered grey-blue core with gradient from darker to clearer blue!
Note the central area with small quartz crystals.
A superb agate, of high decorative interest!
Ex coll. Rollet family (Lyon).
The Rollet family owned several mines in Madagascar since 1920, prospecting for new deposits, mining and exporting minerals for industrial uses (mainly phlogopite) but also gemstone roughs and collectable specimens. Founder Marc Rollet was a very early mineral dealer in France. The collection features many specimens of historical and systematic interest from Madagascar, as well as a variety of French and international classics from the last century.
