What you're looking at
Feldspar is the most common mineral you'll find in rocks and minerals all around you. It's a key ingredient in granite, sand, and countless geological formations. When you see it in its natural form, it looks like a dull crystalline rock, often pale or whitish in colour.
When magnified to this extreme level, the feldspar cleavage surface shows a strikingly smooth, flat plane with subtle geometric patterns and reflective qualities. The extreme close-up removes all context about scale and shape, making it almost impossible to recognise. What appears as a shiny, abstract texture at this magnification is actually the perfect breaking plane within the crystal's atomic structure.
Search for smooth, reflective planes with subtle geometric striations or lines running across them.
