Agate Slice and Quartz Coloring Page

A large oval agate slice dominates the center of this printable, its concentric rings radiating outward from a solid core like geological growth rings on a cross-section. Surrounding it, quartz crystal clusters rise in pointed formations, their flat faceted planes meeting at sharp angles. Scattered smaller stones and a rough rock surface fill the remaining space, grounding the arrangement with irregular, chunky shapes. The agate's banded rings are great for practicing gradient work - try moving from deep burgundy or violet at the center outward through rose, peach, and cream to mimic natural stone coloring. Crystal faces on the quartz formations need sharp color transitions between adjacent planes to suggest the way light catches cut stone, so keeping each facet a slightly different tone adds convincing dimension. The rough background texture between pieces benefits from warm grays and tawny browns to contrast the cooler jewel tones of the gems themselves.
