How to distinguish between tourmaline and crystal? In addition to taking professional testing agencies to detect, is there an easy way for ordinary consumers to quickly distinguish between the two? The appearance of tourmaline and crystal makes many consumers mistakenly think that the high-grade crystal is tourmaline, tourmaline and crystal are the same kind of items.
