This is the sacred green stone that one day could be declared as Guatemala´s National Stone due to its importance and relation with the cultures of Mesoamerica. According to scientists and historians, The Mayans attributed to it… wealth, power, status and most importantly “life”.  They associated this beautiful green stone with a mystical passport to a supernatural world, named “Xibalba”, or The Underworld. The pieces they made are now considered masterpieces, Jade treasures found in several tombs along the Mayan World, from Mexico to Costa Rica.  Among these treasures: bracelets, rings, ankle bracelets, craniums with dental incrustations, and the amazing work of mosaic pieces. These included: King Pakal´s Funerary Mask or the masterpieces from Tikal, the mosaic Portrait Funerary Vase that belonged to Yikin Chaan Kawl or the beautiful mosaic mask from the Burial 160, probably belonging to Kalomte Balam. Currenlty, Jade must be processed with Industrial Diamond Equipment because of its hardness, which will be described later in this text.  Formed two thousand years ago, without knowledge of electricity or other contemporary equipment, ancient Jade pieces carved by the Maya do not compare to current pieces.  This fact leads us to ask the following question: How did The Maya carve Jade?
