Arsenopyrite in Quartz Value Guide

This mineral specimen showcases a striking band of metallic silver-gray arsenopyrite embedded within a stark white quartz matrix, originating from the United States. As the primary ore of arsenic, this hydrothermal vein formation is highly collectible for its distinct crystalline structure and its famous ability to emit a garlic-like odor when struck.

What Is Arsenopyrite in Quartz Worth?

The typical price range for Arsenopyrite in Quartz is $20 - $22 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The distinct contrast and definition between the silver-gray arsenopyrite and the white quartz matrix.
• The overall size and weight of the specimen, currently valued in the $20 to $22 range.
• The preservation of the metallic luster and the lack of significant oxidation on the arsenopyrite surfaces.
• The quality of the hydrothermal crystallization and the visibility of the mineral banding.

How to Identify Arsenopyrite in Quartz?

• Look for the characteristic metallic silver-gray luster of the arsenopyrite bands against the opaque white quartz.
• Verify the specimen's origin as the United States, dating from the modern 2000-2024 era.
• Identify the hydrothermal vein formation where the minerals have crystallized together from mineral-rich fluids.
• Note the heavy weight and brittle tenacity typical of authentic arsenopyrite deposits.

History of Arsenopyrite in Quartz

Arsenopyrite is the most common arsenic mineral and has been mined since antiquity as a primary source of arsenic. When struck with a hammer, it famously emits a strong garlic odor, a tell-tale sign of its arsenic content. This specimen represents a typical hydrothermal vein formation where minerals crystallize from hot, mineral-rich fluids.
