Only 3500 units of the Samsung Galaxy S4 Crystal Edition are being made available, and to buy one you have to go to a Samsung Store in Thailand. The price of the phone is 20,300 baht ($634.17 USD), while the regular Samsung Galaxy S4 is priced at 17,300 baht ($540.46).
If you like to have a unique phone that is also quite capable, you're going to be hard pressed to find something that tops this. With only 3500 availabe, better start making plans for that long flight to Thailand.
The Samsung Galaxy S4 in crystal is available from Samsung in Thailand
