David Guery, 41, was born and raised in Sedan, France, and has been selling fossils and other earth-embedded objects for the past 13 years. He attended his first gem show with his grandpa in France when he was 8 years old and took joy and relaxation from uncovering fossils from their casts.

What started as a hobby for him became a job after he left his factory position.

[…]

Finding trusted suppliers such as the one in South Dakota is crucial for the Guerys’ business. Much of David’s tenure as a fossil seller has been spent building and maintaining relationships with miners and lapidaries (people who cuts and polishes gems) from around the world, particularly Madagascar and Morocco.

He has spent weeks at a time traveling to hand pick the pieces and stones he wants. ” – Colorado Springs Gazette
