This is a much less commonly seen variety of petrified wood that comes from logs occasionally found in the northernmost parts of Arizona. This is the same area that can sometimes produce logs covered with a rare fossil fungus that are particularly desirable among collectors. This log actually had several slabs that showed large fungal attachments but this particular slice only barely started to intersect a couple of them (left edge of first photo). As ...you move further north beyond the more famous Rainbow wood deposit the petrified wood that is found on a few scattered ranches takes on a very different characteristic. These are uncommon and absolutely beautiful petrified wood specimens that start to show some of the same mineralogical habit as their cousins in Southern Utah. The wood is actually much better preserved than its more famous cousin showing finely detailed microscopic conifer structure and easily visible growth rings in the entire face. The dried pith with calcite looks just like what you'll find in Utah (for example) and rarely in the Rainbow wood further south. This larger sized slab is very nicely agatized and took a magnificent polish as only the best grades of petrified wood can. The burst of color hidden inside this gem fossil and revealed in our mirror polishing is simply amazing! The darker color and dark orange agate veins really accentuate the brilliant color that this 200 million year old fossil is preserved in. This looks to be an Araucaria (an ancient conifer). This cut is the heel end of the log, rough and naturally weathered on the back. Of course we've polished this fine specimen to a mirror finish to reveal all the color and fossil wood structure in ever detail! I don't often get top grade examples of petrified wood from Arizona and what I do see is usually table top size and not very easy for a collector to display. This particular log is an exception to both rules. I didn't find it, but I sure wish I had! It's one of the better preserved medium sized petrified wood logs I've seen from the northern part of that state and deserves a place in your collection as well. I'm pretty sure most of the petrified logs found in this particular area are Araucaria, and the structure in this one is consistent with those. The cell structure of most of these super old conifer like trees are very difficult to separate just in cross section no matter how well defined they are and this one is no exception.If you're new to our shop the one thing you should expect is to see an unexpectedly glossy finish on each stone we prepare. This complete round is a wonderful example of the best lapidary work you'll find. It's been cut with a diamond saw and flat lapped on equipment I built myself to produce a mirror perfect polish unmatched by any of our many would-be imitators. The detail captured and revealed through the highly polished surface is just immaculate. It's easily some of the best fossil wood to be found anywhere! The rings are gorgeous, the agate is highly polished and the detail is easier to see in person than the photo suggests. It's a truly special find and we won't likely have a lot more so get a piece for your collection while it's available! It measures about 10 3/4" x 10 1/4" across the widest point across the polished face. It is a maximum of about 1.53" thick. Weight is 5.78 lbs.A nice, unique natural wonder collectible exclusively from Sticks-in-Stones Lapidary!
