World-Renowned Gem Carver Tom Munsteiner Dies at 54
The gemstone cutter is remembered for his contributions to the lapidary community and his hearty laugh.

His wife Jutta Munsteiner was with him.
He was 54.
The owner of Atelier Munsteiner in Stipshausen, Munsteiner was a world-renowned carver who took a bold approach to his unique cutting styles. He took home many AGTA Spectrum Awards for his cuts over the course of his career.
A Munsteiner gemstone is a work of art, and Tom was a true visionary of lapidary works.
He will be remembered fondly for his hearty laugh and for sharing his knowledge with others in the lapidary community.
Tom learned gem carving from his father Bernd Munsteiner, another renowned artist who was born into a family of gem cutters in Germany.
Bernd’s artistic approach to the craft allowed Tom to further the field of gem sculpting, developing his personal style of creative genius within the gemstones, making them highly collectible and valuable.
He is survived by his parents Hanne and Bernd Munsteiner, wife Jutta, and son Philipp.
Jutta and Philipp will carry on the family business alongside their team in Germany.
The family encourages attendees of GJX show in Tucson, Arizona, or the Tucson Fine Mineral Gallery to visit the Atelier Munsteiner booth to honor Tom’s life and recall his passion for gems.
The family also is requesting privacy as they prepare services to honor Tom, his legacy to the gem world and his family.
“In peace, we wish our friends, clients, and colleagues around the world a happy and prosperous New Year. Thank you for your respect and support,” the Munsteiner family said.
