As soon as the first scout makes the first confused report, Elilandemilaki flies down to the planet to check it out herself. It doesn't take long to verify.
Some of the organic life on this planet looks like people. And they are people. Oh, they're not gems, bizarre superficial resemblance aside, but they're definitely sapient.
She halts production at both kindergartens. No new gems are to begin incubating until she's had a chance to investigate further. Then she personally studies the locals. They're fairly ordinary as organic life goes, except for the sapience. Language-using, tool-making, shelter-building... it doesn't take her long to realize the implications. Organic life takes so few resources to develop. They're not immortal - fairly fragile, actually, she verifies that early on - but that's surely a solvable problem in the long term, and in the meantime, the implications are staggering. If they successfully integrated these people into gem society, they could gain so much.
It might be a hard sell with the other Diamonds, but she thinks she has a chance. She returns to the lunar base to make her report.
"Andemilakinei, I have interesting news."
