You earn Diamonds by converting your daily steps in Stepler.
You can also earn Diamonds in other ways, such as playing games, answering Surveys and inviting friends.
Diamonds are a currency with three decimal places. For example, if your balance shows 1,238 Diamonds, you have one full Diamond and 238 thousandths of a Diamond — not 1,238 Diamonds.
Smaller amounts of Diamonds add up over time until they become full Diamonds.
