Yesterday, I was asked which gemstone would be most healing for breast cancer.
My feeling would be to suggest Rose Quartz, if it is a gift for someone else. Rose Quartz has an association with self-love and deep inner healing which would help to bring comfort and strength.
If you were choosing a gemstone for yourself, along with Rose Quartz, I would suggest any gemstone (or gemstones) that you feel particularly drawn to at the time. I know it can be quite confusing with so many gemstones to choose from, but usually we are drawn to particular gems at different times in our lives, when we need the particular energy that the chosen gemstone can give us. If the gemstones you choose feel “right”, then they are the ones that will work for you.
What is most important to remember when using gemstones for healing, is that the power of healing energy is only as strong as the intent to heal.
