The 67 Adventures

The new rule here is that for every 2x2 quadrant overlapped by a pink diamond, the four digits (which may repeat) must sum to at least 20. The Negative Constraint is that every 2x2 quadrant without a pink diamond over it must sum to less than 20.
Normal Sudoku rules apply, and normal German Whisper rules apply (i.e. adjacent digits on a green line must differ by at least 5).
Here is the SudokuPad link, and have fun!
Lösungscode: Row 1 left-to-right

We're going on a gem hunt, and challenging our assumptions along the way! What a beauty.

As a guiding HINT, if you are stuck midway through the puzzle, observe R9C6 in regards to Box 8.

no bifurcation is needed, and won't be useful anyway.
there is ALWAYS a pressure point (or a few), but they can be hard to find.
for efficient solution, put a colour splash in a designated corner of each quad that is satisfied.
CREATOR COMMENT: "In my test solve, I took a very long time solving it, but you're right. I use bifurcation regularly but I didn't use any here."

please, no dark background (for printing purposes). Thanks
CREATOR COMMENT: "Got it, I assumed everyone used the SudokuPad and didn't print it. I'll keep it simple next time"
