This magma may intrude into the surrounding and overlying rocks, spreading outward from the main mass along zones of weakness or fractures.

After some of the magma has crystallized into solid minerals, the fluid magma remaining near the edge of the mass tends to concentrate water, silica, oxygen, and some other elements. Rose quartz forms as magma slowly migrates up through the Earth's crust and cools miles below the surface (unlike an eruption that reaches the surface). It forms at high temperatures deep within the earth, while most quartz forms at much lower temperatures from silicon-rich solutions. Rose quartz is formed in large veins within volcanic rocks.

The researchers proposed the name 'dididumortierite' (Nadin, 2007) for this new mineral. Even more recent analysis using other techniques have shown the microscopic fibers are a new mineral that is closely related to dumortierite. An x-ray diffraction study in 1987 showed that it was due to neither of these but rather due to the inclusion of microscopic fibers which were thought to be the mineral dumortierite. Originally it was assumed to either be due to rutile inclusions of Titanium Dioxide within the quartz masses, or irradiated 'color centers' as is the case with amethyst and smoky quartz. The exact cause of the color was debated for years. Rose quartz is evenly colored with masses ranging from pink to almost purple.
