What about the double ALS:
(2=9)r6c249 - (9=2)r4c3,r5c13,r6c1 - loop => -12 r4c2, -1 r12c3, -34 r6c8, -39 r6c5; stte
(as is usually the case, same eliminations as leren's SDQ)

What's a diamond puzzle?

There seems to be mutiple types of puzzles that could be considered a diamond puzzle.

One version would be considered a sudoku variant.

You have asked this question before (Aug 13, 2020) and already got detailed explanation here.
Then, you asked later (Jul 08, 2021) again here (the explanation being already available in links in that thread).
