I made a pattern and then used it here, you can find that pattern in my gallery, it is a .pat file for Photoshop
If you want to do it yourself: 1- Make a hexagon. 2- Make 6 more copies of that same hexagon. 3- Open this file [link] and position them in the same way they fit inside the delimited rectangle, you have to select the area inside the rectangle and make the pattern of that selection. 4- Enjoy.
Then applied some sharpen filters, duplicated and overlayed the image at 50% for more shine, round/light Transparent-Black gradient overlayed on top, smoke brushes for some details and used some filters of Color FX Pro extension, specially the Bleach Bypass (used it twice I think).
Something like that bor, I don't really remember was years ago DX
