The main difference between Black Obsidian and Rainbow Obsidian is that Rainbow Obsidian brings the energetic signature of the rainbow. Think about how you feel when you see a rainbow. There is a magical, mystical nature to rainbows that tends to bring out our child-like wonder and awe. When it comes to healing or doing shadow work, it is so important to bring these qualities to the healing process—to bring this elevated rainbow frequency into the darkness or the unknown.Our Rainbow Obsidian comes from Mexico and is rare in comparison to standard Black Obsidian.We offer other Rare Obsidians as well, such as Silver Sheen Obsidian and Gold Sheen Obsidian. You can take a closer look here. Pay attention to the energies you feel when you look at each of them. They each offer a unique vibration and will resonate with each woman in different ways.Keep in mind, the rare versions of obsidian are still obsidian, just as the rare star rose quartz is still just rose quartz. It is important to remember that though definitions can be helpful, you will create your own connection to your chosen crystal and in doing so, the crystal will express what is best for you
