Definitely an interesting juxtaposition. Reading up on diamonds they sound so unglamorous!
Diamond is a metastable allotrope of carbon…
The cutter has to decide which flaws are to be removed by the cutting and which could be kept.
The diamond can be split by a single, well calculated blow of a hammer to a pointed tool, which is quick, but risky. Alternatively, it can be cut with a diamond saw, which is a more reliable but tedious procedure. WIKIPEDIA
The pairing that is so often a feature of haiku works so well here!
__ Of course Rebecca, I may be accused of disrespect and ignorance in my response to your fine verse, but that is certainly not my intent. With a deep smile, my "juxtaposition" is a metaphoric view of that universal "diamond". Haiku / senryu; read by other eyes; the change. Smiles! _m
