Ninja Turtle is fairly unique in that it has bright yellow and green sections separated by a flowing ribbon of black. It will make you feel like a superhero. It's a bold look that works well in both titanium and black zirconium. The ring can be made in three grades of titanium, black zirconium, cobalt chrome, or stainless steel. The titanium or other metal helps to protect the inlay from damage. Our Executive Series rings are as beautiful as they are unique. Width options in 6mm, 7mm, and 8mm. The inlays are scaled to fit. The ring shown is 8mm wide. Inside ring engraving is available.
