#9 & #7: +very nicely simplified (all necessary messages come across right away)
However, they are somehow a bit too simplified...doesn't look modern (given the shadings and 3D effects which are possible and common today. Can you please "play" with elegent shadings and maybe even 3D based on the template of #9 & # 7?
Furthermore : + fond ok (try Calibri or Arial as well please) . Please also "play" with the letter Z of the name Ziemer (the Ziemer family is in the 5th generation in the Diamond industry) . Can you find a way to combine 3 key elements: 1. Great family heritage of Ziemer family 2. Swissness 3. Elegance
