Query: Lots of tiny stones.

Sadly I found lots of tiny stones in the batch of quinoa I received. Other than the stones that order was perfect, fast shipping, great packaging and fresh looking quinoa. But I will not be eating any more of this quinoa for fear of chipping a tooth. It's not a pleasant eating experience when every few bites you get that awful crunch from a stone.I'm going back to the 'Ancient Harvest' brand. I've never had such quality issues with Ancient Harvest.
