Ok then let's follow a very easy and simple tutorial to make crystalised World globes
(World Globes with reflections) 
First find a world map you wish to use for the globe 
Then Open a new Design canvas (256x256 pix) in Photoshop. and place your picture (map) as a layer.
Select Eleptical Marque tool and drow a Circle while pressing Shift key


Then, press Ctrl+Shift+I to invert selection & select the map layer,
Hit delete.
Extra:* If you need go to Filter liquify and use 'Bloat tool' to make the selected part of the map looks like a part of
a sphere 
Press Ctrl+Shift+I again to return to normal selection don't deselect it.
Press Ctrl+Shift+N to create a new layer and place it above the map layer, then select the overlay mode for the layer.
Select Black to transparent gradient and drow it from the bottom to top of the selection.

Contract the selection by 2 or 3 pixels (Select>Modify>Contract)
Create another new layer, and drow a white to transparent gradient from bottom to top.
then press 'M' to return to marque tool and move the selection upwards.(like in picture)

Hit delete. & Set an opacity around 30%-40%
Then in a new layer above all, drow another marque selection like this,

Then drow a white to ransparent gradient from top to the bottom of the selection
Set opasity of the layer to 75%
Ctrl+Shift+N to Create another new layer and Ctrl click on map thumbnail to select the border,
Expand the selection by 3 pixels.
Fill the area with White (#FFFFFF)
Contract the selection by 4 pixels and hit delete.
apply a gaussian blur 4 pixels (maybe vary)
Ctrl click again on the map layer, Then press iCtrl+Shift+I to invert selection and hit delete. (you can do the same thing by applying an 'Inner glow' effect to the map layer
)
So now you've finished with the crystalised Globe

You can add different reflection styles and different maps to customize your collection of world globes. 
Here is a sample 

Guys, (& ofcourse girls
) what do you think??
