Daily Quest Rewards

I skipped one day about two days ago, and my gems dropped from 1300 to 1000 💎 ( ˊᵕˋ ;)💦 But after that, I did them every day without skipping, and they recovered to 1300 💎. Do they decrease if you skip? Or was it just a coincidence? For now, I'll just keep doing the daily quests diligently while they're available... (ง •̀_•́)ง
