It rains solid diamonds on Uranus and Neptune. Elon Musk will fill Olympic stadium sized auto-piloted  space crafts with them. Instead of paying $25k here for a Tiffany rock or less for one man equivalent made on Earth, the naive will pay $1m for a space rock for the prestige, provenance, branding. Same shit different status. Massive increase in thrust could make a one year harvesting return trip manageble.

Kaizen

An Amsterdam diamond polisher looks at the diamond through a lupe before polishing.

Kaizen is a Japanese word meaning, roughly, continuous, gradual improvement as in the polishing of a diamond.
