The brazilian material is for real. There was a GIA article about it. Moreover, while I've never examined any of these myself, just from looking at the pictures (surface features and inclusions) they look natural. Anyway I seriously doubt it is even possible to synthesize such included quartz, at best you could re-grow damaged terminations of a natural included quartz crystal via hydrothermal ...

Forms as an alteration product of biotite or phlogopite, by weathering or hydrothermal action.Vermiculite is mined as a natural insulation material. The best exfoliation properties were observed not for pure vermiculite, but for intergrowths of vermiculite and other layer silicates (e.g. hydrobiotite). Naturally expanded vermiculite can occur in volcanic rocks.
