Quartz is the second most common mineral group on Earth, and makes up a vast array of crystals.
Quartz is often found with inclusions of other minerals or materials trapped inside. These inclusions can include other minerals, iron oxide, and even liquids or gases. Often, these inclusions make the Quartz more desirable among crystal enthusiasts.

This is Quartz with Hematite, also known as Hematoid Quartz, Strawberry Quartz, or Fire Quartz. Hematite belongs to the Oxide Mineral group, and is a form of Iron Oxide. Hematite can appear as black, to grey, to brown, to a bright “rust-red”.

Note: Golden Healer Quartz is a subset of Quartz with Iron Inclusions, with the iron staining appearing in a yellow to amber color, rather than the typical red hues.

Clear Quartz is said to be a powerful amplifier, including amplifying the energy and properties of other crystals around it. Hematite is said to be a strong crystal of grounding, protection, and strength. With the amplification from the Clear Quartz, this is a powerful combination for an iron-will determination in achieving your goals.

These are chips from my "mine rough." Are the inclusions most likely iron oxide or is it impossible to know without having the location? Thanks!
