Gemdle

A mineral identification game built on a library of more than 250 stones. The daily challenge shows five specimen photos, each to be matched with the correct crystal, rock or gemstone, followed by explanations of colour, lustre and hardness. An endless quiz, a stone identifier filtered by observable traits and an A–Z guide accompany it.
