Jasper!

Brecciated Jasper is a form of jasper, which is a variety of chalcedony, a microcrystalline quartz. Here's what characterizes brecciated jasper:

Appearance: Brecciated jasper has a distinctive look due to its formation process. It consists of angular, sharp-edged fragments (breccia) of jasper cemented together by another mineral, often more jasper or quartz. This creates a mosaic-like pattern where you can see different colors and textures pieced together, giving it a unique, broken or fragmented appearance.
Color: The colors can vary widely but are commonly red, brown, yellow, and sometimes green or black. The matrix or cementing material might contrast with the fragments, enhancing the visual appeal.
Formation: Brecciation occurs when rocks are broken into fragments by geological processes like faulting, weathering, or other forms of tectonic activity. These fragments are then cemented back together over time by mineral-rich fluids. In the case of brecciated jasper, the fragments are jasper, and they're often cemented by the same or similar mineral composition.
Properties:
Hardness: Like all jasper, brecciated jasper has a hardness of about 6.5 to 7 on the Mohs scale, making it suitable for various types of jewelry and decorative items.
Luster: It typically has a waxy to dull luster when unpolished, but polishing can bring out a more vitreous shine.
Uses:
Jewelry: Due to its attractive patterns and colors, brecciated jasper is often used in beads, cabochons, and other ornamental pieces.
Decorative Stones: It's also used in carvings, decorative stones, and sometimes in architecture for its aesthetic appeal.
Metaphysical Properties: In the realm of crystal healing or metaphysical beliefs, brecciated jasper is thought to combine the properties of jasper (grounding, stabilizing) with the energizing effects of hematite if present, promoting physical vitality and emotional stability.
Geographical Locations: Brecciated jasper can be found in various parts of the world where jasper is abundant, including but not limited to the United States, particularly in states like Oregon, Idaho, and Arizona, as well as in Brazil and India.

When collecting or purchasing brecciated jasper, enthusiasts look for pieces with clear patterns, vibrant colors, and interesting contrasts between the jasper fragments and the matrix. Remember, the exact appearance can vary greatly from one location to another due to differences in the minerals involved and the geological history of the area where it was formed.
