I think the border block is diamonds. Quilting on a Roll has a paper pattern for it, but may not be the right size:

I also think it is a Pineapple Star block:

I'm thinking that the diamonds in the border would actually be a portion of that block -- the blue diamond being the white space between the two star points.
Edit: It looks like the original photo is from Russia or some other country that uses a different alphabet (perhaps East European?). This makes me think a pattern is not available and you will have to draft your own. Electric Quilt could help with that.
