Corundum Var. Ruby - Marble quarries Prilep, North Macedonia
 Former Robert Scheck Collection
 Model-like crystallized ruby in a beautiful pink color.
 Rubies from Prilep are known for their typical pink color, but this intensity is extremely rare. In addition to its color intensity, the crystal's impressive size of 5 cm is impressive.
 The dolomite marble near Prilep contains numerous calcite veins with idiomorphic corundum and rutile crystals.
 Flawless collector's item from Macedonia.
