a teaspoon of Himalayan pink salt contains 1680 milligrams of sodium.
no magic pinkness
My Himalayan salt is very coarse, whereas table salt is fine, so the overall product mass of a spoonful might be less.
I once visited Hawaii and was surprised to see dramatically different colors of sand beaches, one quite orange-red, another very black, etc, I was startled to see anything outside the narrow beige-to-tan spectrum that I was accustomed to.
Significant chemical differences from place to place seem pretty natural.
