glowing rune stones 3d model

Six small flat rune stones, dark gray stone, size about 15x25 mm, each with sharp chipped jagged edges and irregular silhouettes, rougher than smooth pebbles, game-ready props. On the front of every stone, the same simple engraved vertical line rune "I". On the back of each stone, a different engraved fantasy emblem inspired by stylized faction crests or rune path icons from a MOBA game, each back symbol unique but in the same graphic style, clean silhouettes, medium complexity.
