The Element band is made from Titanium and any Elements you desire to provide for the ring. I can use things like rock, wood, plants, bone etc.. The only material I can't use are translucent materials. Please text or call me if you are sending your own Elements so I can be sure they are usable 541-414-7938. If you do not contact me I will assume you want The Pine Tree band in the photo. That design is made out of Pine Tree Bark, Pine Needles and Neon Greean Moss. Millimeter width varies depending on size of ring. Can be made in sizes 6-15. If a bigger size is needed please email me. All sales final.
