Yellow Calcite can stimulate the intellect. It can help organize intellectual thoughts & information. I think it generally helps me with all aspects of organization. It can boost one's energy level & increase one's personal power, hope, & sense of self-worth. It's also known to be helpful for meditation, or used to assist with channeling, intuitive awareness, shamanic work, & similar activities. In the physical, it has been used to benefit the stomach, upper intestines, upper back & upper spine. These are only some of the metaphysical properties associated with Pineapple Yellow colored Calcite, however there are many different colors of natural Calcite found in the world & it naturally forms in so many different & unique ways, therefore it's highly collected & having multiple colors of calcite on hand, then you get the combined energies & then also calcite in general has an abundance of information out there & it's a good idea to get multiple perspectives if your still learning because everyone is different! Thank you in advance for any purchase you have made from me & remember that even though you are purchasing my crystals from Amazon & through Prime, that they are the Storage & Delivery System to get them to you Safely & Quickly, however I have put my everything into Acquiring them & preparing them for the Journey & For You!
