Create new photoshop document of 600 x 600 pixel filled with white background and name it Plate.
Press shortcut Ctrl+Shift+N for creating new layer and type layer name "Base Plate"
Press M to select "Elliptical Marquee Tool" and take mouse pointer to the center of document, now press and hold alt+shift and drag mouse to create perfect circle.
Fill Circle with color code B5B7B4.
Duplicate "Plate Base" layer by right clicking on it and choosing command duplicate. Rename this new layer to "Plate Depth". Now both layers are identical, we will fill newly created layer with some other color. Ctrl+Click on "Plate Depth" layer and fill selection with green color. Press ctrl+T for free transform, press and hold alt+shift to reduce it size accurately
Click on fx button and from pop-up menu, choose command "Bevel and Emboss". Make sure that "Plate Depth" is selected.

Result after applying emboss effect.
Double click on effects of "Plate Depth" layer and set parameter of gradient overlay as shown below.
In this step we will define two color for our gradient overlay, double click on small button to set their colors.
The Basic plate is completed so far.
Create new layer and name it highlight. Take hard brush, set its size to 2 px, set foreground to white. Select pen tool and draw path for highlight.
The path has been successfully drawn, we need to stroke it simulating pressure. "Convert Point Tool" is still selected, right click on path and choose command "Stroke path".
If you are not familiar and comfortable with pen tool then it is highly recommend to take some time and get control on pen tool. Another way for creating highlights is to draw them by brush tool. Although creating these type of highlights with pen tool is very fast and accurate.
Make sure to check mark "simulate pressure".
Duplicate highlight layer, rename it "highlight 02" and place as shown in image.
Double click on background layer to make it normal layer. Fill backgroud color with color code "353952" and "626B8A" , with the help of rectangular marquee tool.
Create new layer above highlight02 layer, name it "Edge highlight" and draw another path for plate edge highlight.
Stroke path with white color using simulate pressure option as we did before. Size of Hard brush is 2 px.
Create last highlight of plate edge at right side with pen tool and stroke with 2px brush pressure with white color..
Placement of 4 highlight.
The plate is complete. These step are optional for making plate more beautiful and realistic. Any flower picture can also be used for decorating it. In this step I am using photoshop default shapes for this purpose.
Select custom shape tool , click on shape layer button, select leave2 shape and draw leave custom shape.
Create another leave shape, rotate and resize with free transform tool. Shape will be fill with foreground color.
Select both leave custom shape layers, right click and choose command "Merge layers", which will merge and rasterize both layers.
Apply Filter - Blur - guassian blur of 0.5 radius to merged leaves layer.
Set blending mode of leaves layer to multiply and reduce opacity to 60.
Finally create new layer above background and name it shadow. Now draw some shadow with soft brush as shown in picture.
