Concentric ringed crater bowl — stepped contour terraces descending to a central drainage well

Caldera

A crater of concentric rings, built to hold a garden in miniature.

$64

Caldera reads as geology: stepped concentric rings descend toward a wide, shallow crater, each layer a contour line you can run a thumb across. The broad mouth and low profile give a succulent arrangement room to spread laterally, while the central well drains through a recessed hole into a slip-fit saucer hidden beneath the lowest ring. Matte walls catch raking light along every ridge, so the form shifts as the day moves around it.

The story

We modeled Caldera from topographic contour maps of collapsed volcanic cones — the way a crater terraces inward in clean, deliberate steps. Each printed ring is a literal layer line made structural, turning the planter's geometry into a record of how it was grown. It is built low and wide on purpose: succulents sprawl, and a crater gives them somewhere to go.
