Dark reds!

The rock in the image appears to be a type of agate, likely with some unique features:

Banding and Patterns: The rock shows banding patterns which are characteristic of agates. These bands are typically formed by the deposition of silica from groundwater in cavities within volcanic rocks.
Colors: The colors range from white to orange and yellow, with some areas appearing to have greenish hues. This variety of colors can be due to inclusions of minerals like iron oxides or other trace elements.
Texture: The texture seems somewhat rough and natural, indicating it might not have been polished or significantly altered from its natural state.

Agates are known for their beauty and are often used in jewelry and decorative items.
