Many people may wonder why Black Mountain Stone does not appear truly black-especially after processing. The reason is that during the cutting and grinding process, the stone's surface becomes abraded, resulting in a grayish appearance. This effect is further accentuated by the reflection of sunlight, making it look even more gray. However, when Black Mountain Stone is wet, it reverts to its deep black color; once it dries, it turns gray again.

 

To preserve this "wet look," processors apply a transparent stone sealant to the surface of the Black Mountain Stone. This not only ensures the wet appearance endures over time but also restores the stone to its true, natural color. Consequently, processed Black Mountain Stone is typically treated with this sealant so that it consistently retains the look of being wet.

 

In summary, the interplay between the "wet" and "dry" aesthetics of Black Mountain Stone is achieved through the application of stone sealant-a technique that not only enhances the stone's beauty but also allows it to display distinct visual characteristics across various environmental conditions.
