This puzzle is greatly inspired by Index Fingers (created by marty_sears). Please check that one out and you won't regret it.

Rules:

• Normal 6x6 sudoku rules apply.
• There are four diamonds hidden in the grid. No two diamonds may share the same row, column or box.
• Clue lines: All four coloured lines in the grid are clue lines, each corresponding to exactly one unique diamond. None of the diamonds are located on a clue line. The four digits ABCD along a clue line, reading from the circle to the end, indicate that the associated diamond is in row A, column B, box C, and contains the digit D in that cell.
