Earth tone jasper!

This rock chunk is a type of jasper, specifically a variety known as "picture jasper." Jasper is an opaque, impure variety of silica, typically composed of an aggregate of microgranular quartz and/or chalcedony along with other mineral phases. Here's why it might be picture jasper:

Color: The rock has a warm, earthy tone with shades of brown, yellow, and hints of red, which are common in jasper varieties.

Patterns: The inclusions and patterns resemble landscape scenes or abstract images, which is characteristic of picture jasper. These patterns are due to the deposition of iron or other minerals within the rock during its formation.

Key Characteristics of Jasper:
Hardness: Jasper is relatively hard, typically around 6.5 to 7 on the Mohs scale, making it suitable for various uses like in jewelry or as a decorative stone.
Luster: It has a waxy to dull luster.
Varieties: Jasper comes in many colors and patterns, often named based on their appearance or location (e.g., red jasper, green jasper, ocean jasper).

Usage: Jasper has been historically valued for its beauty and durability. It's used in ornaments, beads, and for carvings. Its patterns and colors make it popular for making cameos, intaglios, and other decorative items.

If you're interested in its value, jasper's worth can vary greatly depending on the quality, rarity, and the intricacy of its patterns. However, most jasper is relatively affordable compared to gemstones like diamonds or emeralds.
