If the calcium is from naturally-occuring calcium carbonate minerals, it will contain admixtures of other materials, including heavy metals. It is probably safer to consume calcium additives that have been formed as precipitates in a well-regulated production environment. "Natural" is a word that many people equate with "safe" and that's just not so. There's a lot of stuff hat occurs naturally that will kill you if breathed, drunk, or eaten.
