This beautiful black and grey Agate center reminds me of Castle Peak that I saw when I was just a young girl! I kept this one simple and clean!! The strap was purchased because of its color and feel!! I am not sure what type of material it is made of, but my educated guess is leather! It is soft, subtle and matches perfectly!! If you hold the stone up to a light you can actually see through some of it! This lady would like to come home to match your outing/outfit!! Castle Peak is the ninth highest summit of the Rocky Mountains of North America and the U.S. state of Colorado. The prominent 14,279-foot fourteener is the highest summit of the Elk Mountains and the Maroon Bells-Snowmass Wilderness This necklace took over 31 hours to complete. I used peyote stitch to complete it. The center is made without the use of GLUE or BACKING. The center sets inside beads that are between 11o and 15o (this means there are between 11 - 15 beads per inch). Necklace measures at 17 - 19.5 inches in length and can be lengthened if needed. Center hangs down 2.5 inches from top of strap.
