What Stoneline Group does

Stoneline Group LLC is a privately held US importer, distributor, and wholesaler of premium natural stone products, operating for over 40 years from its Miami, Florida headquarters with additional showrooms in Pompano Beach and Naples. The company sources marble, travertine, and limestone directly from quarries in Turkey, where it operates manufacturing facilities that combine traditional craftsmanship with modern fabrication techniques to produce pavers, tiles, coping, veneers, and stone mosaics across multiple finishes (sandblasted, leathered, tumbled, honed, polished). Its product portfolio has expanded to include a glass mosaic collection of 20+ color variants, porcelain pool tiles, fluted architectural wall panels, and Portland White cement, addressing outdoor paving, pool decks, patios, bathrooms, kitchens, and interior feature wall applications.

Stoneline sells through a hybrid physical-channel model: showrooms serve South Florida luxury residential and design customers, while a 200,000 sq ft distribution facility near the Port of Savannah, Georgia supports East Coast wholesale customers (Florida, Georgia, South Carolina, North Carolina, Virginia, Maryland, New York), and a newer Dallas, Texas branch serves Texas markets. The company maintains a long-standing strategic supplier partnership with DN Mermer, a Turkish natural stone producer, ensuring source-level quality control and supply chain stability.

Go-to-market targets four customer segments — luxury residential homeowners, architects and interior designers (primary), pool builders and landscape contractors (primary), and hospitality/commercial developers — through design-professional specification, showroom traffic, contractor relationships, and a content-driven digital presence including SEO, an Instagram channel (@stoneline_group), and Pinterest. Pricing is quote-based and project-specific with no public list pricing, and revenue is generated via one-time wholesale and retail transactions rather than recurring contracts.
