Axel, with your example there is little to tell; just watch the  
typeset result. Clearly, the shape of the "diamonds" is not that of a  
"lozenge". LaTeX's \Diamond is larger than TeX's \diamond, and  
matches better with \square or \Box in the usual formulas of modal  
logic. Typographical traditions in each field makes one used to see  
certain symbols in certain shapes and sizes.

The strange thing is that, wanting to completely replace all math  
symbols from CM fonts, LaTeX fonts and AMS fonts, the Lucida  
designers made \Diamond equal to \lozenge...
