Lechatelierite Value Guide

Lechatelierite is a rare mineraloid silica glass formed exclusively under extreme thermal conditions, such as meteorite impacts or lightning strikes. Named after French chemist Henri Louis Le Chatelier, this material is highly collectible for its association with high-energy geological and extraterrestrial events.

What Is Lechatelierite Worth?

The typical price range for Lechatelierite is $50 - $100 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Origin of formation, with impact-related specimens often fetching higher prices than common fulgurites.
• Size and weight of the specimen, typically valued between $50 and $100 for standard collector pieces.
• Clarity and color, where inclusions or unique flow patterns can increase desirability.
• Historical or scientific significance of the specific site where the sample was recovered.

How to Identify Lechatelierite?

• Look for a vitreous, glass-like luster with a transparent to translucent appearance.
• Identify the presence of microscopic bubbles or flow structures typical of rapid cooling.
• Verify the context of the find, as it is often found within fulgurites or impactites like moldavite.
• Check for a lack of crystalline structure, as it is an amorphous silica glass.

History of Lechatelierite

Lechatelierite is a naturally occurring silica glass that forms under conditions of extreme heat and pressure, typically from impact events like meteorite strikes or intense lightning strikes known as fulgurites. Its presence in geological samples can provide valuable insights into the intense energy events that shaped a particular area, or even extraterrestrial bodies. The name comes from Henri Louis Le Chatelier, a French chemist who first synthesized it in a laboratory.
