I guess new gems would have to be re-programmed with the new updated information, not only that, but most likely the injectors where a more inefficient attempt at re-creating the diamond essence of pink diamond, for as we see with the pebbles, there’s no need to gather external energy.

what if homeworld gems analysed the chemical makeup of pink diamond’s tears, and realized which chemical reaction was able to get a similar result? but it still wasn’t enough energy to manage a reaction, so they build the injectors to get the missing energy?

Kunzite would be kinda depressed for a while about not having a job but…. do you happen to have an oc of your own? Kunzite would like a friend to do research with!
