Depends on the particular purplish crystal. Amethyst is not too expensive but other purplish crystals expensive. So it depends.
Amethyst crystals are actually quartz (SiO2) crystals with a purplish hue derived from impurities of iron and aluminum. The crystalline structure forms from the latticework arrangement of silicon and oxygen atoms unique to quartz. Quartz crystals like amethyst can develop from silica saturated solutions or even from molten silica solutions.
