As a general rule, an intermediate block is rarely more difficult to make -- it just contains more pieces and therefore more seams. This is the reason that it is important that you can sew an accurate quarter inch seam allowance. Once you have mastered a precise seam allowance, you will have no difficulty in sewing the majority of quilt blocks.

The Diamond Star quilt block can only be named as such (at least in my opinion) because it has squares set on point, looking like 'diamonds'. There are actually no diamond patches in this quilt block and so, as a result, it is much easier in the construction process. (Diamond patches tend to get over-handled resulting in distorted pieces). So the fact that there are no diamond patches is a good thing!
This block is fun to make, and gives a little variation on the usual 'star' quilt blocks. There are both large and small pieces so it is an enjoyable process to make the final product.
