The plant has been spotted at several sites of kimberlite, but does not seem to be found elsewhere - suggesting it only forms in these areas, and could indicate potential diamond spots. One of the major benefits of this is that geobotany is much more cost effective - and fewer regions would need to be scavenged in the hunt for diamonds.

— A plant that commonly grows on top of diamond deposits is called "diamond-bearing soil." This type of soil is found in many parts of the world and is often associated with kimberlite pipes, which are the most likely source of diamonds.The soil itself is not made of diamonds, but rather contains a high concentration of them.

— Kimberlite with diamond photo provided by Chance's Minerals. When people want to find diamonds, they look for kimberlite pipes. These are carrot-shaped channels where kimberlite has come up from deep below. Once they locate these pipes, mining begins! Miners dig deep, sometimes creating huge pits or tunnels, to reach kimberlite.
