Looks like classic, poorly-diffracting “potato” crystals to me. Will need additional optimisation to convince them into a nicer morphology. No diffraction indicates that they are likely not to be salt at least.

Hi all We have been trying with no success to crystalize a protein. Recently we got these strange shape "crystals". They are hard and flat but they do not diffract at all. Any ideas as to what could cause this?
