Diamonds are earned in small amounts and can be purchased in larger amounts in the Shop. Diamonds are super valuable. You can use them to speed up timers, buy missing materials, and Energy refills too.
There are several ways to get them:
- You can buy Diamonds in the Shop
- When you remove trees and stones from Orchid Island
- Sometimes they are found in Star Boxes
- Diamonds are occasionally awarded as bonuses for finishing Hidden Object Scenes (but very rarely)
