Pink dolomite crystals form saddle-shaped aggregates on a pale matrix. Their delicate pink to deeper pink coloration and vitreous to pearly luster give the specimen a balanced, clearly structured appearance.
The curved crystal surfaces are characteristic of saddle-shaped dolomite. The individual aggregates are distributed across the surface and stand out clearly against the paler matrix.
