Dave Becker is a marble artist from Longmont, Colorado who works under the name Blackhawk Agates. A stone mason by trade, he began crafting marbles about 15 years ago using polymer clay baked in a kitchen oven rather than traditional glass. His pieces are known for their flame designs, vibrant colors, and sparkling effects, often echoing the look of classic machine-made marbles but with a distinctive modern flair. Collectors recognize his work for its artistry and unique “bling,” making him a respected figure in the contemporary handmade marble community.
