Stone International

What Stone International does

Stone International is an Indian natural stone trading firm headquartered in Surat, Gujarat, and operating as a sole proprietorship under Sunil Diwanchand Chowdhary since December 1981. The firm sources and supplies dimensional natural stones — granite, marble, sandstone, limestone, quartzite, and slate — from Indian quarries and processes them into a broad catalog of formats including slabs, tiles, paving stones, cobblestones, stepping stones, staircases, pool coping, borders, mosaics, thin veneer, stack stones, panels, aggregates, and monuments. It offers a documented capability set of more than 15 surface finishes (polished, honed, flamed, leather, sand blasted, Lapatora, glacial, and grooved textures among others), positioning itself on format and finish versatility rather than single-SKU depth.

Beyond physical product supply, Stone International provides trade facilitation services for the natural stone industry, including documentation support, customs coordination, logistics optimization, and regulatory compliance assistance aligned with the WTO Trade Facilification Agreement. Shipping uses 20-foot TEU-high cube containers with capacity up to 27.5 tons, supporting global delivery and just-in-time inventory replenishment for large format retailers. Its customer base is horizontally segmented across exporters, importers, institutional partners, architects and designers, DIY consumers, and large format retailers — with a marquee reference in the JSW Balaji Temple project (Nandayal, Andhra Pradesh) for supply of Kadappa Black Limestone.

The revenue model is based on one-time product transactions (natural stone sales) combined with trade facilitation services revenue. Pricing is not publicly disclosed; quotes are obtained via WhatsApp, Telegram, and email. The firm markets through a content-heavy WordPress website organized into educational categories (durable stones, logistics, stone care, sustainability, art and architecture) and maintains an active organic presence across Facebook, Instagram, LinkedIn, X, and YouTube under the Durable Stones brand. The business is privately held and founder-operated with no disclosed institutional capital.
