Her's a video on making it:
Step 1: Materials
-5 square (origami) pieces of paper. Using larger pieces will make it easier to put together.
If you want to make one like the picture, you will also need:
-length of string
-centerpiece symbol (you can chose what you want for the center)
Step 2: Making the Shards
Start off with one piece of paper and fold it diagonally in half. Fold the side corners along the diagonal fold, then fold the upper tips along the diagonal fold also. Take the previous folds and fold them along their creases as shown. Then, fold the paper in half, hiding the upper tip under the shown flaps. Fold the bottom corners along the center, the turn the paper over and fold the edges from there. Repeat until you have all 5 shards.
