Xiuhhuacan (Mdz13r)
This simplex glyph for turquoise (xihuitl) stands for the place name Xiuhhuacan. The visual source for the "hua" (possession) syllable is unclear. The locative suffix (-can) is not shown visually. The sign is basically round with an inner circle that has two small compartments painted red, and around the outer circle are four evenly-place smaller circles. All but the two red compartments are painted turquoise.

The shape suggests a gleaming turquoise stone, but it could also share a reading of "year." Sometimes, the turquoise part of this glyph could be filled with small pieces of turquoise mosaic, such as has been published from a cache found at the Templo Mayor. Small turquoise pieces were easier to come by, and so they were often assembled in mosaic fashion. [See: J. Alden Mason, "Turquoise Mosaics from Northern Mexico," Museum Journal (Penn Museum), 20:2 (1929).]
