Smithsonite

Smithsonite, also called zinc spar, is the mineral form of zinc carbonate. Wikipedia says it was named in 1832 for James Smithson, was long confused with hemimorphite, is variably coloured, and usually forms earthy, rounded masses, only rarely well-formed crystals. Hall describes it as pearly and lustrous, in colours including pink, green, blue, purple, brown, yellow and white-grey, from the United States, Australia, Greece, Italy, Mexico and Namibia. Hall associates it with tranquillity, kindness and favourable outcomes, with releasing stress, with harmony and diplomacy, and with leadership where tact is needed. She also links it to aligning the chakras and strengthening psychic abilities, and says to carry it, place it at the crown, put pink pieces over the heart or thymus, or grid it around the bed. Her statements about the immune system, infertility and other health matters are her own claims and are not vouched for here. Hall describes blue-green, lavender and yellow sorts separately.
