Hello,
I just noticed this minor thing (unsure if it's a localization issue or not, but it seems more that than a bug).
When you hover over a search result on the MB for any crystal-type item, the bottom of the tooltip displays "Market Prohibited" next to "Unsellable". This doesn't happen when hovering over them in the Item Search window, only in the Search Results window.
