Size: Small Square Biscuit. ABSTRACT NAVAJO JASPER IS MORE DEFINED IN ITS DALI-ESQUE DISTINCT PATTERNS AND MORE GLASSY IN NATURE]. Navajo Jasper are quickly becoming Local Stone favorites. Exclusive to the Brewer County Texas Big Bend Region, these red beauties have the patterns and qualities of Navajo blankets, with a touch of Picasso Stone figures and landscapes. We call them red-strippers when we find them because they are so distinctive from all the other rocks we normally find in that region. With reds, yellows, purples, blues and oranges, these stones hold the elements of fire and earth within them like no others.
