This is a Pre-Columbian MAYAN Shard / Pendant from Pueblo Bonito, Mexico, 300 - 900 A.D. A jeweler worked on this item with sterling silver so that it can be used as a pendant. It measures about 1 1/8" X 1 1/8" X 1/4" ( 2.9 cm X 2.9 cm X 0.6 cm ). The Mayans were a Mesoamerican Civilization that developed a complete written language system in the Pre-Columbian era. Their art, architecture, mathematical and astrological systems influenced their surroundings, covering an area of about 620 miles, including the modern-day countries of Honduras, Guatemala, Belize, Northern El Salvador, and Central Mexico. The Early Preclassic Mayan Period introduced pottery and fired clay figurines. The Mayans traded cacao, salt, seashells, jade, and obsidian. The Mayan Stepped Pyramids were built in their religious centers and they accompanied the palaces of their rulers. Mayan art reflects high level of aesthetics and artisanal sophistication. Their carvings and reliefs show their observation of the human form and daily events. Advanced painting on their ceramics show their technique and knowledge for mixing colors. There is a beautiful turquoise blue color that survived over the centuries due to its unique chemical characteristic. This blue color is known as Maya Blue or Azul Maya. Mayan murals show great artistic and iconographic perfection.
