This is an absolutely exquisitely preserved tree fern round cut from the center of a colorful, and complete tree fern log. It's a particularly nicely preserved Tietea singularis and the finish on this mirror polished specimen must be seen to be believed. The entire specimen highly agatized and took a wonderful polish! Just look at the magnificent detail revealed in the polished face of one of these gorgeous fossils u...nder magnification! A few years ago in Tucson I saw some fabulous petrified tree fern specimens the likes of which I'd never laid eyes on. They were detailed, fascinating in their structure, and very colorful. They had the typical (poor) import polish on them, but I purchased several nearly complete specimens, brought them home and reworked them into truly beautiful collectibles. Since then, I've tracked down the one miner who can legally export these fossils and visited his home and his claim in Brazil. The trip would leave me talking for days, but I'll leave that for our website. What you can see here is one of the world class tree fern specimens we imported as a result of that trip. The fossils are reminiscent of petrified palm with a very interesting and unusual "heart". The outer portion of the round looks a lot like palm wood with little rice grain like patterns uniformly distributed around it (this is the root mantle). The interior section is made up of a larger, less dense pattern where the heart appears to be made up of thick macaroni or brain shaped patterns (these are the bundled fern xylem and they have the most spectacularly beautiful honeycomb cell structure under a 10x loupe that you've ever seen!). This species is Tietea singularis, and comes from the Tocantins state in Brazil. The only thing that rivals the incredible detail in these ancient fossils is the colors that they're preserved in. The best of these specimens are captured in brilliant reds, yellows, purples and other appealing colors. It's a Permian fossil which makes it about 1/4 of a Billion years old! This log was preserved with exceptionally good quality agate that took a beautiful finish. It's preserved in a greater variety of colors than any other single log I've cut or seen! By selecting the specimens myself, I was able to choose those that could be worked into the finest show case specimens. I've cut, lapped and polished them on equipment I built myself to produce world class display specimens unlike anything you'll ever find in a retail shop. It takes a lot of dedication and attention to detail to produce real cabinet specimens worthy of a place in the finest petrified wood collections and at Sticks-in-Stones Lapidary, that's how we treat every piece we produce! Our finishes are second to none - really!! This complete round is cut from the center of a nice sized petrified tree fern log. It also has tons of fossil detail revealed in the mirror polished face. It's very solid and well preserved. If the timeless mystery of this piece isn't enough for you, then I'm certain the simple, natural, gemmy beauty of it will be. It measures about 6" x 4 1/8" across the mirror polished face and is cut about 0.44" thick. Weight is 0.78 lbs.
