Bestone Quartz Surfaces is able to produce the largest quartz slab size:  3500*2000 mm / 139*78 inches with both 20mm/2cm & 30mm/3cm thickness. We are very confident to introduce the largest quartz stone slab size in the market with high quality. Our quartz stone is produced with up-to-date technology and fresh mined natural quartz stone grains, which makes the product resistant to external forces. During production process, resin and couplings are necessarily added to provide a certain flexibility to the product and minimize the fragile attribute. Hence a thermal shock might cause damage to the resin and the stone surface. What's more, when the quartz surfaces are exposed to direct sunlight for a long time, the whole slab might be warped and the color will be faded away because of the UV light. Therefore, a certain handling guidance must be applied when it comes to unload, store, fabricate and install the quartz stone surfaces.

Artistic Visual Statement with Lasting Elegance
Black Gold is a bold and visually captivating quartz stone that combines deep black tones with rich golden veining. Its luxurious marble-like pattern makes it a standout material for contemporary and high-end interiors. While visually expressive, it retains the engineered benefits of quartz—providing both style and structural stability. Whether used as a surface centerpiece or background detail, the artistic flow of the pattern adds depth and distinction. The color palette is ideal for clients who favor dramatic yet timeless aesthetics. It offers a strong alternative to Calacatta Statuario without the natural stone's fragility or maintenance demands.

This product is available in various formats, including the super jumbo quartz slab size of 3530×2030 mm (139"×79"), jumbo quartz slab size of 3230×1630 mm (127"×64"), and standard 3030×1430 mm (119"×56"). The large surface area enables designers and fabricators to create expansive installations with minimal seams. As part of Bestone’s jumbo quartz slabs collection, this flexibility in sizing helps reduce cutting and material loss while supporting custom applications in both residential and commercial projects. The versatility in dimensions ensures that every space—from compact kitchens to open-concept living areas—can benefit from seamless visual impact.

Durable Composition and Premium Finish Options
Black Gold is manufactured using 92–93% natural quartz, with resin and coupling agents precisely integrated to increase strength, reduce brittleness, and enhance surface quality. The result is a high-performance slab resistant to stains, scratches, heat, and external impact. Clients may choose from polished, matt (honed), or leather finishes depending on the aesthetic or tactile experience desired. Unlike natural marble or Calacatta quartz stone, this jumbo quartz slab requires no sealing and offers reliable long-term performance in demanding environments.
