Gypsum is distinctivly soft (2 on the Moh's Scale, can be scratched with a fingernail) and light (SG of about 2.3.) Crystals are flexible but not elastic, which means that you can bend 'em, but they don't spring back, they stay bent. Typically colorless, white or grey, but it can also be brown, yellow, red. Luster is vitreous to pearly. Transparent to translucent. Monoclinic crystal system, with cleavage good in one direction and distinct in two others. Streak is white. Crystals typically tabular, bladed, or blocky, often twinned, also found in massive, crusty, granular, earthy, and fibrous forms.
When it comes to making an identification in the field, best clues are it's softness, flexibility of crystals, and distinctive twins, which can look like fishtails.
