1: Put it in the freezer for a couple of hours then hit it (on the back) with a hammer this should make the jewel fall out (if not then goto 2)
2: Heat the jewel from the back until it gets warm on top (just warm to the touch) then you can use a small screwdriver to lift it and then slide something like a butter knife (for better control) under it and lift it off (be carefull not to scratch the case)
Heating can be done with a hair dryer, steam or many other ways just dont use anything that can/will melt the plastic and ALWAYS heat from the backside to avoid discoloration on the top
To get the black adhesive of the back of the jewel just put the jewel in a cool place for a couple of minutes then youll be able to remove it in one big piece in seconds.
Sanding:
If you get some adhesive tape and make a "handle" and glue/hotmelt the sandpaper to a hard flat surface, it
will give you better control and let you apply more pressure when sanding.
Fold the tape and place it over the jewel
Cut the excess tape
When preparing the sandpaper only use hotmelt in the corners, the "sanding area" needs to be flat
If you have deep scratches in your jewel you will need to start with a low grit sandpaper
(360 grit)
When the scratches are more or less switch to a higher grit until all the scratches are gone
(600 grit)
A little more sanding
(1200 grit)
(1200 grit with water)
The jewel should now look something like this
Polishing:
If you want it crystal clear you need to polish it
Get a piece of paper and tape it to a flat hard surface
Now grab you favorite toothpaste
no this is not a joke the toothpaste will work like a high grit sandpaper
(Brasso, CD scratch remover or a clearcoat can also clear up your jewel).Dab the jewel in the paste a couple of times so it will even out over a larger area, now "sand" away.
The end result is a nice and crystal clear jewel.
