This is the Gem icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
The icon had a octagon shape at the center of it and is surrounded by various triangle shapes both upside down and right side up. Under the triangles at the very bottom are to upside down right angle triangles. Together they all form a gem-like shape.
