Thulite, the naturally occurring pink variety of the mineral Zoisite, can range in color from pale pink to deep rose to rusty red depending on the concentration of Manganese. First discovered in Sweden in the 1830s. Metaphysically, Thulite is very similar to Rose Quartz. It encourages unconditional self-love and acceptance. It is also said to aid artists in the emotional process of bringing forth authentic and vulnerable work.
