The Brooks Range is hand crafted out of exotic ebony and has a silver offset inlay. The main feature of this band is the ivory colored inlay. It is Dall Sheep horn from Alaska. Many dream of harvesting such an amazing animal. Some go and fail and some go an conquer. Regardless of your success, this ring will help to remind you of the journey you made or even the dream you have to chase these beautiful animals. A Titanium band is used for strength and durability. I provide the sheep horn unless you would like to yourself. Millimeter width varies depending on size of ring. Can be made in sizes 6-15. If a bigger or smaller size is needed please email me. All sales final.
