Mark Henry Co. is the pioneer behind the rarest gemstone on earth, the natural alexandrite.

Mark Henry Co. have established themselves as a premiere jewelry house responsible for reintroducing the alexandrite gem to the world. Mark Henry's devotion to this fine gem is what ultimately led to the availability of what was once considered an unattainable treasure. This has been a guiding foundation of the family operated company since its inception in 2004.

“For any person to dedicate his life into a single little object, and work exclusively with that, you must be totally blown away with that variety of species. You must be captured by it. This is exactly how I feel about the alexandrite gem itself.”
