Couchy Creek Thundereggs
Pronounced coo-chee creek, this is a rare Australian location characterised by an extremely soft matrix, almost the consistency of chalk. The cores are usually pale grey-brown agate and crystal, sometimes with complex inclusions. For polishing, consolidation with glue/resin may be advisable. Below you can see a consolidated specimen (first) and two unconsolidated ones showing visible wear. Please note though that the unconsolidated ones have been ground into a smooth round shape!
