Item Description

This is a hard to find polished stone of rarely seen petrified palm root (Arecaceae) from Garut in West Java, Indonesia. For reference, Arecaceae are defined as tropical trees usually having a tall columnar trunk bearing a crown of very large leaves; coextensive with the order Palmales. This material was newly discovered in March of 2021, and is distinctly different from old petrified palm that we've seen from Indonesia in the past. It should be noted that this is more of a pseudomorph in my mind as, this is actually a replacement of the wood by cryptocrystalline Quartz (most likely Chalcedony). During the replacement process, tree trunks were buried under several hundred yards of sediment. Over the course of time the wood was replaced by Chalcedony which was carried in underground waters. Due to the slow steady process, even the most minute details of the woody structure was preserved. This "Triangle Cabochon" cut gem features beautiful patches of soft blue and white Chalcedony in the space between the cells of the tree root. You can see the "grain" of the wood (the darker colored portions of the gem), and they make a great contrast against the Chalcedony. The stone actually passes light when strongly backlit on the edges as well. If you collect unique stones in the Quartz family, don't miss out on this one, as it's really eye-catching and different!
