Diamond Storms

We have identified the source of the unusual mass readings on …. The planet's atmosphere is composed primarily of carbon-rich methane gas, which solidifies into ultra-dense diamond structures as gravitational pressure increases. Due to the planet's fierce storm cycles, the phenomenon gives rise to fast-moving diamond storms. While these diamonds are easy to extract for our own needs, … is confident that closer examination of their density and purity will yield further valuable results.

The command below will trigger the "Diamond Storms" event in Stellaris:

When this event fires, you can choose between the following option:
