The Fascinating World of Quartz Inclusions

Quartz is known for its wide range of colors and intriguing inclusions. These inclusions can form through various processes and add unique features to the quartz. Here’s a simplified overview of how inclusions form and the types you might find:

How Inclusions Form in Quartz

Protogenetic Inclusions: These are inclusions that were present before the quartz formed. As the quartz crystallizes around them, they become part of the crystal.
Syngenetic Inclusions: These inclusions form at the same time as the quartz crystal, growing together in harmony.
Exsolution Process: Elements that are initially part of the quartz might separate out as conditions change, forming new minerals within the quartz.
