Material:
According to Katie Ridder, granite can be found in three different varieties or qualities, and each can have a very profound impact on your dining table. While all three quality levels can make wonderful surfaces, a level 1 granite surface will look drastically different from a level 3 quality surface. When sourcing your granite, try to view it in person and determine whether or not the depth of pattern and color is what you want in your home.
Construction:
When dealing with granite, you need to be sure the different quality levels are constructed properly. David Netto says that level 1 granite will require additional supportive backing on tables and countertops while level 3 granite will not. The differences in thickness is drastic, as well as how prone to breaking or cracking these surfaces may be. Always be sure you know where your granite was mined and which quality it is before purchasing.
Aesthetic:
Granite can add a stunning aesthetic to any home, but granite itself can be highly variable in color, shade, and depth of patterns. According to Suzanne Kasler, granite can be found in various shades of pink, gray, white, and black. The quality level and amount of quartz can also affect the depth of color, as well as the reflective qualities. Each slab of granite can offer a different aesthetic to your home simply due to where it was mined and the quality of the cuts.
Size:
Dining tables can be found in a wide range of sizes, and if you have a large family or do a lot of entertaining on the holidays, a large and spacious banquet type table may be required. However, keep in mind that large slabs of granite can be heavy, costly, and difficult to source in some cases. For granite topped dining tables, modest sizes may be more reasonable, although Ken Fulk says nothing looks more grand in your home than a spacious granite banquet table.
