Well, it was bound to happen, and it looks it will happen rather soon. Samsung has revealed that it will be launching a Crystal Collection for the Galaxy S5, in similar vein to earlier devices like the Galaxy S4, in South Korea in May. As usual, the Crystal Edition S5s will be studded with Swarovski crystals on the back for a more glam and flashy look, but will otherwise remain unchanged. Well, the pricing will be considerably higher than the standard model, but that's to be expected when you're looking to make a fashion statement.
More details should crop up on the Galaxy S5 Crystal Edition soon, but in the meantime, you can watch the short teaser video below.
