Rainbows make me happy. When I can’t decide what my favorite color of the moment is, I err on the side of all of them, which is why rainbows are an easy choice.
Rather than try and find pieces that are all rainbows all the time (it would be a very short list), let’s break it down by color. I always remember the colors of the rainbow by Roy G. Biv (or Red, Orange, Yellow, Green, Blue, Indigo, Violet). There are so many stones that could fit into each category—or most of them—that I’ll just cover my favorites and call it a day.
Red: Sponge Coral
Yes, it’s an actual coral, which was at one time a living organism. It gets its name from the holes that are created by the polyps that formed it, making it look like a, well, sponge. Sponge coral comes in many colors, but it is more commonly found in the red-orange-brown family. Take care with your sponge coral jewelry, since it’s fairly soft and scratches easily.
