Mark Henry was founded more than 40 years ago in New York City as the leading purveyor of Brazilian Alexandrite. Our offering has since evolved to include finished jewelry in other important colored gems including Paraiba, Moonstone, Sapphire, Emerald and Ruby... all set in 18K gold with a design aesthetic that brings a fresh, modern interpretation to classic designs. Our family-run jewelry house still stays true to its original desire for showcasing the rare and exceptional. We partner with the best retailers in the country and bring them market differentiation while helping their sales teams develop and grow the high-potential category of fine color.
