22 1/4" X 22 1/4" ceramic tile medallion.  The medallion is made from the following Datile tiles:

Skybrige SY98 (dark gray color, outside border pieces),
Skybridge SY95 (light color, pebble pieces),
Glass flower pieces are a dark brown with a black center dot.
 
Medallion can be used in a tile back splash, I would not recommend for a floor due to the glass pieces, because they can scratch over time.  Medallion is mesh mounted for easy installation.  Tile thickness is 5/16".  Ship UPS.  Please e-mail me with any questions.
