Overall, it is a very nice fire pit and fits our needs.  Size is great and works well. The darker color is a nice charcoal color. I'm not sure what the material is, but it is not concrete and does not weigh 88 pounds like the description says.  Maybe 30 pounds max.  It is not solid - it is a molded material and the underside is completely hallow.  We replaced the lava rock with reflective glass and it looks much better. I would definitely recommend this for the price - but just know you are not getting a heavy concrete table.
