Green Jasper!

This rock appears to be a type of jasper, specifically a variety known as "picture jasper" or "jasper breccia." Here's why:

Color and Texture: Jasper typically comes in red, yellow, brown, or green, but it can also appear in other colors. The rock in the image has a mix of colors, including shades of green, yellow, brown, and some red, which is common for jasper. The texture looks smooth and somewhat waxy, which is also characteristic of jasper.
Patterning: The rock has a pattern that resembles landscapes or pictures, which is typical of "picture jasper." This type of jasper is known for its scenic patterns, often mimicking natural scenes like mountains, rivers, or deserts.
Translucency: While jasper is generally opaque, some varieties can have translucent bands or patches, as seen in the image.
Hardness: Jasper is relatively hard, ranking around 6.5 to 7 on the Mohs hardness scale. This makes it durable enough to be polished to a high sheen, which might be why the rock looks so smooth.
