Other proposals included the presence of irradiation induced color centers, similar to amethyst or smoky quartz, either in included minerals, or in the quartz substance itself. For the past 30-40 years it was assumed that rutile TiO 2 inclusions are the cause. The debate about the cause of the color is slowly settling, although there are still a few open questions. Rose quartz is usually very evenly colored. The color can vary from a very bright pink to almost purple. Quartz crystals of a similar color are called pink quartz.

Rose quartz is used as an ornamental stone or as decoration and is one of the most popular semiprecious gem stones. pink quartz develops crystals while rose quartz does not. both varieties form in different environments, and pink quartz is sensitive to light, while rose quartz is not the cause of their color is not the same, Despite being macrocrystalline varieties of similar color, rose quartz and pink quartz should be treated as different varieties as: The pink variety of quartz that forms crystals is called pink quartz and is covered in its own section. Rose quartz can be grainy, but the material used for lapidary purposes is built more homogeneously, like the specimen of unknown origin to the right. It is not a cryptocrystalline variety, however, as it is made up of many intergrown crystal subindividuals. It is never transparent, and it does not form crystal faces or crystals.

Rose quartz is a pink variety of quartz that occurs in large translucent masses.
