Mark Henry 2.31 Carat Paraiba Tourmaline and Diamond Cocktail Ring

Mark Henry is the pioneer behind the rarest gemstone on earth, the natural alexandrite. We are gemstone specialists and master jewelry artisans with over three decades of jewelry making experience. We have an affinity for truly unique and exotic raw materials and employ a scrupulous attention to detail in our design process. Our company was founded and continues to be headquartered in New York City, however, we search the globe with an industrious curiosity in order to showcase only the rarest of Earth's treasures. In recent years we have broadened our philosophy to integrate other exotic gemstones that are not widely available. Our company supports a transparent and sustainable value chain, implied by the fact that we are one of only a few brands that deal directly with mining operators and fine jewelry connoisseurs alike.
