THUYA WOOD. Tetraclinis (or Thuya) is a coniferous mountain cypress tree indigenous to the western Atlas Mountains of North Africa. This unique tree produces a large underground root with many outgrowths. Its burl is dense with a high oil content, and its color varies from a rich golden brown to nearly black. "Thuya," meaning sacrifice, was named by the Greeks because they used the oil distilled from it as incense in their religious ceremonies. These boxes are hand made by local craftsmen in a small town called Essaouira in Morocco. The finish is a hand rubbed shellac.
