Botryoidal Hematite Value Guide

Botryoidal Hematite, often referred to as 'kidney ore,' is a prized mineral specimen known for its distinctive bubbly or grape-like crystal habit. These specific Moroccan examples from the 2020-2024 era are highly collectible due to their unique rounded geometry and deep metallic sheen.

What Is Botryoidal Hematite Worth?

The typical price range for Botryoidal Hematite is $35 - $38 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The prominence and uniformity of the bubbly 'kidney ore' formations across the surface of the specimen.
• The quality of the metallic luster, with higher values placed on pieces that exhibit a mirror-like or iridescent finish.
• Overall size and weight of the iron oxide cluster, with the $35-$38 range typically covering mid-sized cabinet specimens.
• The absence of chips or bruising on the delicate rounded surfaces of the crystal habit.

How to Identify Botryoidal Hematite?

• Look for the signature 'botryoidal' habit, which appears as a cluster of smooth, rounded spheres resembling a bunch of grapes.
• Perform a streak test on unglazed porcelain; authentic hematite will leave a characteristic blood-red streak despite its dark exterior.
• Verify the high density and weight of the specimen, as iron oxide is significantly heavier than common look-alike minerals.
• Examine the surface for a bright, sub-metallic to metallic luster typical of high-quality Moroccan hematite.

History of Botryoidal Hematite

Hematite has been utilized by humans for millennia, first as a pigment in cave paintings and later as a primary ore of iron. The name is derived from the Greek word for blood, due to the red streak it leaves when scratched. This specific botryoidal formation, often called kidney ore, is highly sought after by mineral collectors for its unique metallic luster and rounded geometry.
