Try the diamond saw you have first, make a practice cut 1" from the edge,

Sounds like you have a composite sink (basically epoxy and color fillers).
Any toothed blade might make a mess but you do have some room to practice
and test your method.

Thank you and everyone who contributed. I appreciate it. I will drill
a small hole first to see if it is concrete or man-made material. Again
test cut 1/2" (to be safe) from the edge with a diamond masonry circular
saw.

Thanks everyone again.
