Crystals that are red

The most recognisable crystals and gemstones that are red include Copper, Ruby, Garnet, Cinnabar, Jasper, Sandstone. Below is every red stone in Gemdle with photos, Mohs hardness and how to tell them apart — pair it with the guided identifier to narrow down an unknown specimen.
