From one office in Surabaya to showrooms in four cities, a manufacturing plant, and stone in homes, hotels, offices and places of worship.
MM Galleri was founded in 1992, trading rattan and natural stone. Soon after, we began sourcing Lampung crystalline marble from Sumatra, and in 1994 built our own manufacturing.
Our international debut came in 1998, when Lampung marble went into the bathrooms of the Sherry Frontenac in Miami. Since then the collection has grown to cover the world’s quarries, and the work has grown with it: cutting, curving, finishing and installing.


Marble, onyx, granite, travertine and quartzite from quarries around the world, plus SINISO by MM and SINTERRA by MM, our own lines, and Dekton, Silestone, Lapitec and Agglotech.
Our own manufacturing since 1994: cutting, finishing and shaping stone for worktops, cladding, floors and furniture.
Bended curved marble, 8MM ultra-thin stone, Sierra’s carved texture and Silhouette’s stone paintings, developed in our own workshops.
