What type of chalice is this? I was told it was an encrusting and wouldn't really form a cup shape. Trying to decide on placement in my nuvo 10.

do you know if they form a bowl shape out from the rock or if they just encrust the surface of the rock? Thanks

it’s an echinophyllia aspera…

generally they encrust,
but if you starve them of light, they will cup
