Of course, the diamond crystal to grow in the home is not possible. But get yourself a very beautiful crystal salt is possible. Because it is fragile and is afraid of water, it will have to be stored in a transparent box.
Instructions:
1) Decide whether you need the correct crystal or allowed some of its deviations from the correct form (sometimes the second is obtained even nicer). In the first case, the water must be distilled and salt none iodine. In the second case, use water from the tap and any table salt
2) Boil about half a liter of water. While it is boiling, carefully to avoid scalding steam, start to pour salt into it. This can be used, for example, V-shaped sheet metal segment, hands away from the vessel. Continue to pour it until the solution becomes supersaturated (on the vessel walls will form small salt crystals).
3) Soak a piece of cardboard in a supersaturated solution of salt. Then dry it, and it would be covered with small crystals.
4) One of the largest crystals detach and hang on a thread.
5) Supersaturated solution pour into a clean jar so that it does not hit the small crystals from the walls of the vessel in which the boil. Let it cool, then enter into the solution a small crystal on a string. it doesnt touch of the bottom.
6) Leave the container in a place where it will not move. Small crystal will gradually increase in size. When it reaches the desired size you remove it, then dry thoroughly and reload in a transparent box.
7) If you wish to fabricate a device to illuminate the crystal LED. What it will be, it depends on your imagination.
