Crystal wallpapers

Crystals grow in straight lines, and that geometry is what these pictures show. Quartz points clustered like a skyline, a geode split to reveal purple spikes, a cube of pyrite, and polished gemstones with light trapped inside.

All are macro work. The depth of field is thin, so a few facets are razor sharp and the rest dissolves into colour. The surfaces catch light in a way that no flat pattern can imitate, which is why crystals suit large, high-resolution screens.

Colour is wide. Amethyst gives violet and lilac, citrine gold, fluorite green and blue, rose quartz soft pink, and clear quartz almost nothing but light. Dark backgrounds are common, since they make the colour deeper.

For wallpapers, the geode pictures are the strongest on phones, with their dramatic centre. Clusters and rows of points are good for monitors, as the pattern repeats across the width. Polished gems are more refined and suit an office desktop.

The glass page is the nearest neighbour, with man-made transparency, and chrome has the reflective metal version. The macro page has the same kind of detail in other subjects, while botanical shows living structure.
