John is based in Greenwich, Conn., while his mining company is based in Madagascar. Originally working on Wall Street, John later turned his entrepreneurial spirit to Madagascar, the fourth largest island in the world, which he's now visited around 65 times. Starting out with a chocolate and vanilla business, he soon turned his endeavors in Madagascar to mining. All About Giving BackJohn says creating prosperity is his No. 1 goal, hence the name of the company. And with that comes a component of giving back to the community. That's done by reinvesting in the people who work for his company and the community in which they work. But giving back also includes an environmental factor. There's a high level of interdependency between the people of Madagascar, the planet, community relations, and environmental development. What Are Demantoids?Victoria tells us that she's holding a demantoid garnet of John's and asks him to explain why it's so special. He tells us a demantoid garnet is 10,000 times rarer than a diamond. Its signature features are its fire and brilliance, which John believes make it the most beautiful of all the colored gems. Comparing Madagascan demantoids to ones from Russia, John believes his are better because of their sharp and clean crystallization. Victoria asks John about his deposit supplies in the mine, and Rob asks him about how he plans to get the word out about demantoids. Origins Of Madagascan DemantoidsRob asks John how he found out about the mine, how long it took him to get set up, and how deep it is. The mine has been around for about 10 years. John explains how he knew an Italian geologist, Dr. Federico Pezzotta, who stuck with the deposit to study it and establish the potential of the location. Right now, Prosperity Earth is only mining down about 15 to 18 meters-but it should eventually go down to around 200 to 300 meters. Madagascan demantoid is anywhere from 30 to 50% the cost of Russian demantoid. John says he wants to democratize demantoid, making it accessible to designers. The Impact Of MiningBeyond the mining level, Prosperity Earth has a 10-plus person gem-cutting team that does precision faceting. The gem-cutting process is responsible for job creation, making Madagascar not just the origin of the rough gem crystal, but also where the value addition takes place. Rob plays devil's advocate and asks if mining can really have a positive impact on local economies. John says yes. But he also differentiates between various types of mining operations.
