we have had the same case recently - it turned out to be Ca-malonate. It seems that malonate has similar properties as oxalate being insoluble at higher concentrations.

So the question: has anybody seen malonate crystals before? I was wondering whether they could possibly be birefringent, given that the molecular structure is not chiral. The crystals I see are very birefringent. None of the other ingredients is chiral either. In general, my understanding had been that the birefringence was due to the chirality of the molecules/crystals...is this misguided?
