Here are some of my concepts. I've gone for something that's fairly clean and simple, yet striking. Creating an icon that works well within the logo or as a stand alone element, one that can be used for things like favicons or watermarks.
The logos are 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed,
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
Great looking logos, Angus. We are interested in the diamond as there is a model we use that is a diamond shape. Also, the off-set text of Entry #26 is interesting to us.
Perhaps you could sharpen the diamond up (remove the smaller accent lines) and close it up? Also, it looks like gray and red or gray and blue variations are appealing to the team more than the brownish gold.
Try strengthening "Institute" in #124 by bringing in the gold color (two tone). Also, let's loose the drop shadow. Also, make a variation with blue and gold like #25.
