this image mainly done using bevel and emboss in adobe photoshop. next using shadows in layer option.
here im giving some steps to do how to bevel and emboss in adobe photoshop :
1
Activate the layer you want to bevel in the Photoshop layers palette. If you want to bevel a selection within a layer, make the selection and copy it to a new layer (Command + J).
2
Choose "Bevel and Emboss" from the layer styles available at the bottom of the layers palette (the "FX" button). Check "Preview" to see any changes live.
3
Select a bevel style. "Outer Bevel" extrudes the edge outside the selection area, "Inner Bevel" begins the bevel at the edge of the selection and "Emboss" hovers halfway over the selection edge. Adjust the size slider to increase the bevel border and depth to focus the distribution of colors used to create the beveled edge. Use the soften slider to diffuse the bevel corners and inside edge.
4
Change the light direction with the "Angle" command. Positive angles shift the light upward and to the left, negative angles down and to the right. Increase the light intensity by increasing the highlight and shadow opacity sliders.
5
Check the "Contour" option in the Styles menu to the left of the dialogue to change your shape configuration. Click on the contour option and select a custom contour map. Contours with mountains, or ridges, tend to sink the surface area like a tray; contours with valleys raise the surface. Drag the range slider toward 0 (to the left) to soften the contour effects.
6
Add texture to the surface by checking "Texture" in the Styles menu. Photoshop will add a default pattern (usually bubbles). Choose a different pattern to find different pattern presets. Use the scale and depth sliders to control the texture effect.
