Crystals that are clear
Stones get their clear colour from trace elements or inclusions, and the same mineral species can occur in several colours — so colour alone never confirms an identification. The most recognisable crystals and gemstones that are clear include Diamond, Clear Quartz, Borax, Gypsum, Moissanite, Topaz. Below is every clear 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.

Stones that also occur in clear
These minerals are best known in other colours but are also found in clear — so a clear specimen is possible, though the photo here may show a different shade. Confirm the colour of the actual stone, not just the species.
