[PC][2000s] Gnomes And Diamonds
The game had a somewhat cartoonish art style, and you had to control some gnomes that had to mine some diamonds.
I think there were four differently colored kinds of diamonds.
I am pretty sure that the game's desktop icon was a bag full of diamonds.
From what I had heard from another person with the same query, there was a minigame in some volcano area where you hold a purple umbrella over one of the gnomes to protect him.
There was no world to explore and it looked like it was made by BigFish Games.
The gameplay was from a bird's eye view.
