Historical healing properties

It would be a simple stone, a stone that purifies, relaxing when it's pink as rose quartz, but also softer. It cleanses the mind and have a positive effect on cleaning the liver and kidneys. It would help to look at things simply, to avoid complications, to have common sense: it would be perfect to "land" farmers, people close to nature, gardeners. It would facilitate relationships based on simplicity, exchanges between neighbors and friends.
