While the Raman spectra of zircon remained unchanged, except in the region of 1000 cm –1 after heating at 1000☌, the Raman peaks of monazite crystals became sharper with increasing temperature. Raman spectroscopy was used to detect the effect of heat treatment on zircon and monazite crystals. Interestingly, the monazite crystal inclusions changed color from orange-brown to near-colorless after heat treatment. Other common inclusions such as needles, particles, etch tubes, and mica and zircon crystals remained unaffected. Only slight alterations of monazite inclusions and iron stains in fissures were observed following these heating conditions. This study showed that after heat treatment at 800✬, a subtle blue tint was removed, making the color a purer pink. Therefore, characterizing Madagascan pink sapphire before and after heat treatment helps laboratories develop criteria for treatment detection. Pink sapphires from Madagascar, one of the most important sapphire-producing countries, are no exception. Low-temperature heat treatment is often applied to gem corundum to improve its appearance.
