Mark Gronlund, master gem cutter
Some gemstones are cut. Mark Gronlund's are designed.
Among the most honored cutters in America
Mark Gronlund is one of the most celebrated artistic gem cutters working in America. He taught himself goldsmithing in 1988 and started cutting gems professionally in 1995. A year later he won three awards in the Cutting Edge division of the AGTA Spectrum Awards. The American Gem Trade Association runs this competition every year, and it is widely seen as the top honor in the colored gemstone world. Five more awards followed over the next two years.
He has now won more than a dozen AGTA awards, including first place in Innovative Faceting two years running: in 2018 for a 96-carat round spiral blue topaz, and in 2019 for “Beyond,” a 119.65-carat aquamarine. He is also a GIA Graduate Gemologist.
What makes his work different
Curved, concave facets
Most gems are cut with flat facets. Mark cuts curved, concave facets into the back of the stone, and on some stones into the top as well. This pulls in more light and sends it back with more brilliance and color than flat facets can.
Signature cuts, his own machines
His spiral, scallop and starburst cuts are his signature, and he cuts many of them on machines he designed and built himself.
Cut for brilliance, not weight
He will give up carats to get the light right. That's why his stones show even, rich color and so much life.
