Whenever possible, consumers should personally select the slab(s) that will be used to fabricate their countertops. Here’s why:
While there are some granite colors that are generally consistent throughout the slab, many selections have veining and hues that change dramatically from one end to the other. A small sample cannot demonstrate this tendency. Indeed, it is not unusual for a consumer to adamantly deny it matches their choice when the finished product doesn’t appear to match the small sample from which they made their selection.
Not only does the size of the sample make a difference, but the particular granite lot from which your slab is quarried is fundamental to making a selection. If two slabs of granite are sliced from the same block, it is likely they will closely match. On the other hand, if two slabs come from different blocks, then the veining and direction of the grain may be substantially different. Further, if the blocks are cut from different areas of the mountainside, small differences in the mineral composition may create lighter or darker shades as well as influence the veining characteristics. You are simply better off making your final selection on-site and making sure your supplier clearly tags your selection.
