A stromatolite is a sedimentary fossil structure made by prehistoric bacteria colonies, typically cyanobacteria. Stromatolites in fact are still living and forming in some parts of our world today, including Australia, and are among the earliest forms of life—and fossils—on our Earth.

The fossils form in shallow water conditions of lakes or salt water shores. First, cyanobacteria grow in microbial mats. Minerals like calcium carbonate precipitate (crystalize from the water) onto the surface of the mat. The bacteria acts as a glue, cementing it all together with sedimentary debris. Layers build up over time like a bacterial pearl; the name “stromatolite” appropriately means “layered rock” in Greek.

This, however, is not a stromatolite. They are commonly believed to be stromatolites, and you will more often than not see them sold under that name and description. More accurately, they are concretions formed out of beautiful tones of red sandstone material. These sandstone concretions form in a manner similar to stromatolites, but minus the aid of bacteria: mineral-rich waters precipitate barite which binds with sand to form concentric layers around a nucleus. It is a relative of the barite desert rose, which grows clusters of round blade-like ‘petals.’

This shapely specimen makes for an inexpensive large piece to add to your mineral collection or use as decor around the home. I call this one the "Badonkadonk" because when flipped over, it appears as two pert semi-perfect spheres.

UV reactivity Many pseudo-stromatolites from Morocco have faint to moderate fluorescence and phosphorescence under 365 nm UV light. Some areas show brief phosphorescence, but overall reaction is poor.

So nice I bought twice!
Size: H Desk Unfinished 3/4-in and 1/2-in, Size: H Desk Unfinished 3/4-in and 1/2-in
For starters, this is a great buy if it is exactly what you want. For me that was the case and it would have cost me a good $40 or more to replicate it at a big box store. With that said, if you are not planning on using all of the pieces and want a different configuration, this may not be the kit for you. All of the parts inside are just like if you bought it at a local home improvement store. All the pipes need to be cleaned and protected. I personally found that dish soap (dry off immediately after you clean a piece) was the easiest to clean everything and I finished it with some wax. The kit is sturdy and easily supports the weight of my butcher block tops. I inverted the kit as it is designed as I intend on adding a shelf and am planning on using the support brace to aid in holding that shelf up for cable management. After cleaning and protecting, putting the kit together only took 5-10 minutes and that was with kid disruptions. I purchased 2 so that my wife and I could have matching desks in the office and I couldn't be happier.

Durable and sturdy. I bought two
Size: H Desk Unfinished 3/4-in and 1/2-in
Love the kit. I ordered two to make an L-shaped desk for my home office. Perfect height, looks cool, and sturdy. Slightly tricky to get two of them to the exact same height but you can adjust them buy loosing/tightning parts. Way cheaper than going to the hardware store and buying the same parts. I wiped each piece down as they are a bit dirty/greasy, but no big deal.

Great legs - sturdy when fully assembled with tabletop.
Size: H Desk Unfinished 3/4-in and 1/2-in
These legs are great. I put it together with a butcher block tabletop and it turned out beautifully. I recommend using a level on the legs once you get them into position and again when you place a top on it. The screws included were so easy to screw into the block but that will vary depending on the top you select. Watch the videos another reviewer posted on cleaning the legs with a mild soapy water and dry them thoroughly. It really helped me. Also after it was all assembled I used a clear acrylic - in a spray can to clear coat and seal the legs. I am really happy with it.

Exactly what I ordered, took just a few minutes to assemble and mount the legs. Love that the bottoms can be manipulated to give a balanced stance.
