Our Mission is to be leaders in our field, making high-end stone fabrication available to everyone

Our History

Instone Marble was founded in 1998 by Paul Charondo. Working in the stone fabrication business since the early 1990s, Paul quickly mastered the trade, realizing that there was a market for producers to improve the standards on various styles and techniques. His commitment to reinventing the stone fabrication industry led Paul to found his own company, and over the next 20 years, he has mastered his craft, becoming one of the largest fabricators in the Bay Area. Paul prides himself on perfection. He appreciates being a leader in the industry and always has the most cutting-edge technology.
