There are a few ways to do it. If you only have Bryce then make the shape in a program like illustrator then convert it to a bitmap then you apply it to a symetrical lattice. Make sure the size of the image is big over 1000x1000. Then apply a texture from your glass library. Tweak the texture till it looks right. On symetrical lattices the problem is that often there will be a seam in the middle. Another way is if you have a modeler model the logo you want. Now if it is just text most modelers support text so just type it in. Otherwise you will have to model it and that changes depending on wha tkind of modeler you use be it box, spline, Nurbs, patch, or a rails extrusion type. Lat remember to set your number of reflections and transparencies higher for a render like that.

I tend to keep MRD higher then TIR by at least 25%, IMHO, TIR tends not to make a great deal of difference above a TIR of 10 or so

Also, to get the crisp faceted look of the cut crystal, be sure to !!!!---un-smooth----!!! the model.

And a second (third?) thought: You may wish to use a lower poly-count model. The one shown in your own test renders actually look too smooth along the curved sides. Compare the curved bevels on your desired examples. That's where a lot of the difference appears.
