Eh, I wouldn't get your hopes up. They recently started to expand on Kaiburr crystals in the canon. They've become pretty much just lightsaber crystals. In fact, the Death Stars actually use Kaiburr crystals to generate their blasts.
There's nothing in the canon to suggest that they lack mysticism. In fact, that they're both lightsabers crystals and Death Star beam generators suggests magical properties to me.
