Just for the lulz, I decided to sloppily recreate your texture just by using a rounded rectangle and blending options.
Basically, it consists of these things:
- Bevel & Emboss: smooth inner bevel with 1% depth, no size or soften, highlight opacity at 75% and shadows at 35%
- Stroke: 1 px dark gray on the outside
- Satin: 25% opacity with 11 px distance and 16 px size, AA'd and inverted linear contour
- Gradient overlay: reflected style, 100% opacity, gradient spans from white to medium dark gray, at a 130-140 degree angle
- Drop shadow: 40% opacity, 3 px distance, 0% spread, 5 px size
I'm uploading the PSD so you can download the file and check out how the blending options on the layer come together to create the final piece.
