I found this label on a mineral specimen I was checking out in Manchester museum in the pic below.
I love how a natural shape like this mineral can have such amazing angles. There's a design there that looks like it has been made somehow but at the same time it's not perfect, it is just how it's formed from it's structure and environment.
Quartz crystals have a really interesting shape. Slightly prismatic but with nibbled edges like an early glass artefact which has worn but survived underground. A lovely chunk of quartz makes up this one-off ring available at Craft & Culture. The silver lustre brings out the facets of the sculpted ring and it's polished to a metallic shine.
