To wet the appetite of an existing company called this to buy it, your chances are better if its the "COM". If value is realised in the "ORG" (with a company called this that appreciates it), I'd consider that interest to be Low / Mid XXX, but take offers than pin a figure against it, if you are in that situation. From what I read online: "Kimberlite is an igneous rock, which sometimes contains diamonds.". This called an organisation? Tricky. If it was a word like "diamond" or "rock" with an "ORG", it would be in the 5 figure range
I believe you'll have a hard time selling it, IMO. However, best of luck
