If the diamond shown here was originally a dagger grip diamond, then it never would show the wear that we see here: three of the corners are worn off! That can never happen in a dagger grip!

But the picture of the reverse makes it all clear: the prongs have been artificially attached to what was -in the best case- a badge diamond!
