Natural zircon (not to be confused with cubic zirconia) has been used to create convincing diamond imitations. However, this gem is doubly refractive and has a high birefringence. Web1 Answer. Yes, the only crystal system that is guaranteed not to be birefringent is cubic, because all of the other crystal systems have at least one axis distinct from the others. What matters is the symmetry not the centring, so this is equally true for face-centred or body-centred as for primitive crystals. Sadly, however, there is no way to ... opti-lean whey
