They look like a form of spherulites, which don't diffract as is but can likely be optimized by matrix optimization, seeding, and such methods. Or in fact they might just be crystals that need to be optimized into diffracting crystals. Check this link for some ideas:

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?
