Tiny needles of rutile have been given credit for forming the six-ray star of rose quartz for the same amount of time. In the mineralogical literature, the pink color of rose quartz has been attributed to titanium, manganese, and iron by a large number of authors for over 100 years. This piece of rough has great color and would make nice cabochons, or beads, or be used to make tumbled stones in a rock tumbler. Rose Quartz Rough: A rough piece of rose quartz showing its conchoidal fracture, vitreous luster, translucence and pink color. Many people believe that pink transparent quartz should be called "pink quartz" instead of "rose quartz" because the cause of the color is different. Pink transparent quartz is rare, but found in several locations around the world. This color is often unstable, fading with exposure to heat or light. The color of these specimens, especially those that are transparent, is thought to be caused by irradiation-induced color centers. These are usually late-stage mineralizations in pegmatite pockets.
Rarely, quartz occurs as transparent euhedral crystals with a pink color. These inclusions are usually abundant enough to make the rose quartz translucent instead of transparent. The pink color of rose quartz is attributed to microscopic inclusions of a pink variety of the mineral dumortierite. It is usually occurs as massive, anhedral occurrences in hydrothermal veins and pegmatites. It is abundant, common, and found in large quantities at numerous locations around the world. Rose quartz is the name used for pink specimens of the mineral quartz.
