Are the rocks cronchy? We need to know for scientific reasons. In all serious tho, wanted to send a silly ask

Not all of them! For example, this rosasite has a velvety texture.

And this okenite puffball feels positively fluffy!

While I've had the opportunity to feel both of these minerals before (and yes, they ARE as soft and velvety as they look), I would never touch THESE lovely specimens! My fingers would destroy their incredibly delicate crystals.

Okenite geode in basalt

This is a sample of basalt with needly clusters and “cottonballs” of okenite crystals grown in a vug. Okenite (hydrated calcium silicate hydroxide) is an unusual mineral and a member of the tobermorite mineral group. It is most often found in basalt vugs but has also been reported from carbonate rocks at Crestmore, California. Typical associated minerals are zeolites, apophyllite, gyrolite, calcite, quartz and prehnite. When vugs in volcanic rocks are lined with delicate okenite they are sometimes called “okenite geodes”. This sample is 21 cm across.
