Sometimes, I"ll place an order for a stone I hadn't encountered before, because it appeals to me when I'm looking through the catalog to replenish my materials.
Red Sardonyx is like that. I liked the daylights out of it from the moment I saw it, and that was BEFORE I saw it in person. It's a combination of Onyx (which occurs in many colors, not only in black) and Sard, a type of Carnelian. As such, it has all the grounding and energizing properties of both stones, and resonstes with the Root and Sacral Chakras (which govern the life force and the creative force).
And I didn't know, until I actually saw the stone in person, that some of the bands are translucent. Bonus! I love translucent stone.
Because of this, I had to photograph against a white background, since using a dark background didn't do justice to the colors in the translucent areas of the stone.
I just got done listing these on my site. I'm very happy I discovered Red Sardonyx.
