FAQ Quality Control

1. Q: With regard to "color consistency”

A: We can promise we will try our best to ensure color consistent and highest quality. But is there standard for color consistent? Some stones, for example, Blue butterfly get deferent color shade from same block. We will have our best well-experienced employee inspect every blocks. We can promise each unit of products cutting from the same block and pre-installed in the factory to match its color. We do not own any quarry. Although it may be a shortage of us, it is also an advantage. We get freedom to pick out the best quality blocks from the market without pressure to dump the bad quality blocks if we were quarry owner.

2. Q. Does Granite stain?

A: Generally speaking, no. All stone, however, is porous to some extent, but Granite has very little porosity. Most colors will never show any moisture. A few colors may show some moisture if exposed for a period of time. For example, a puddle of water left on the counter for 30 minutes for some colors, may show a dark spot when the water is wiped away. This spot will then dry up and no evidence will show. Only a few colors demonstrate this trait. Our granite has a sealer applied at the fabricator, however some customers prefer to apply a stone sealer (available at tile and granite shops) after the granite is installed.
