Cocoa butter crystals library

Dear all,

I am doing a lot of visual researches with chocolate and cocoa butter bloom. Is there actually a library available anywhere in the world which shows the cocoa butter crystals from different regions or plantations being able to compare such? I know that there is a flavour profiling library available and chemical compositions of different beans but I could not find anything related to bloom and the different visual crystal shapes. Do I have to do it myself?

Thanks for your help.

Best, Gerhard

On my website you find lots of chocolate bloom pictures
