Datolite Value Guide

This pre-1900 American Datolite specimen is a rare mineral find, historically significant for its association with major copper deposits. Its granular structure, which inspired its Greek name 'datysthai', makes it a distinctive addition to any geological collection.

What Is Datolite Worth?

The typical price range for Datolite is $110 - $110 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The presence of dark inclusions can significantly impact the aesthetic appeal and market value of white Datolite.
• Specimens sourced from the Keweenaw Peninsula of Michigan generally command a premium due to their historical copper association.
• The age of the specimen, particularly those documented as pre-1900, adds historical provenance value for serious collectors.

How to Identify Datolite?

• Look for the characteristic white color paired with specific dark mineral inclusions typical of 19th-century US finds.
• Examine the specimen for a granular or massive habit rather than distinct crystal faces, consistent with the 'to divide' etymology.
• Verify the dense, porcelain-like luster that distinguishes high-quality Datolite from common quartz or calcite.

History of Datolite

Datolite is a relatively uncommon mineral, first described in 1806 from specimens found in Norway. Its name comes from the Greek word 'datysthai', meaning 'to divide', referring to the granular structure of some varieties. It is often found in association with copper deposits, particularly in the Keweenaw Peninsula of Michigan, USA, where it forms attractive nodules and masses that are highly prized by collectors.
