" Emeralds are not as hard as sapphire or diamond. For them to end up in a clay deposit the have to be eroded from their igneous matrix, travel a bumpy ride down a mountain and smash against every hard rock in the way...finally settling in the silt."

I know of no alluvial process that would concentrate beryl or corundum crystals of any size in a clay matrix. I suspect that any such deposit would be the result of bedrock weathering in place or with minimal transport.
