What Just Naturstein does

JUST Naturstein GmbH is a German family-owned wholesale distributor and processor of natural stone, ceramic, and quartz composite materials, headquartered in Hartha, Saxony. Founded in 1956 by Heinrich and Margarete Just as a stonemason business in the former GDR, it pivoted into wholesale and processing after German reunification and now operates as the flagship entity of the JUST & DESTAG group, led by Geschäftsführer Harald Just and Heike Adam. The company sources over 500 materials from more than 25 countries, holds roughly 40,000 m² of raw slab inventory and exhibition space, and runs in-house processing including CAD/CAM bridge saws, contour wire saws, and surface-finishing lines, complemented by an own logistics fleet.

The commercial model is B2B-first and field-sales-led, with 11+ territory sales representatives covering all German states plus Austria, Switzerland, and Poland, supported by an inside-sales function and physical showroom at Hartha. Customers are primarily mid-market stonemasonry businesses and natural-stone processors, with secondary service to architecture firms (seminars recognized by German Architects' Chambers), kitchen studios (workshops at the Kitchen Competence Center), and memorial/monument companies through the DESTAG partnership. Revenue streams combine material sales (natural stone, ceramic, quartz, plus the proprietary JUKera indoor ceramic line), value-added processing and finishing services, and paid logistics and delivery. The acquisition of the historic Rochlitzer Porphyr quarries at the end of 2024 added upstream quarry ownership and a regional heritage brand to the portfolio. Channel activity spans trade fairs (Stone+tec, GaLaBau, JUST Hausmesse), dedicated customer seminars and workshops, a 360° virtual showroom tour, and German-language SEO content marketing through the company's material library and customer portal. Distribution flows through the central Hartha hub, a regional sales office in Vacha, the Polish subsidiary Just Stone sp.z.o.o., and a Burghaun outlet operated jointly as DJN with DESTAG.
