Recently, several platy orange-yellow inclusions were observed within a highly transparent colorless quartz crystal (see above, left). These inclusions exhibited an orange-yellow to orange color, a smooth surface, and a glassy luster, with a euhedral or subhedral appearance. Closer inspection revealed that some crystals displayed the typical wedge shape of monoclinic crystals (see above, right). This distinct crystal morphology and vibrant color prompted further investigation into their composition.
Raman spectroscopy identified the inclusions as monazite, a phosphate mineral ((Ce,La,Nd,Th)PO4). Further analysis using X-ray fluorescence confirmed a high concentration of cerium, classifying the inclusions specifically as monazite-(Ce).
