This is a Deltohedron icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
This logo is shaped like an object but it is not easy to explain. It almost looks like some kind of jewel and has many sides to it. The number ten is written on the top of it and maybe it has ten sides.
