Pink quartz, a pink macrocrystalline variety of quartz, was discovered in pegmatites at Rumford, Maine, and first described in mineralogical journals in 1938. But these specimens attracted little attention from mineralogists or collectors at the time. Initially, they were assumed to be a rare, atypical subvariety of rose quartz.
Then in 1959, pegmatite miners in Brazil’s gemstone-rich Minas Gerais state discovered clusters of beautifully developed, terminated, hexagonal quartz prisms. These crystals had water-clear transparency and a pink color that was similar, but not identical to, the color of rose quartz. When these specimens appeared on the collector markets of Europe and the United States, the limited supply was snapped up by both collectors and mineralogists.
Mineralogists soon learned that the color of pink quartz, unlike that of rose quartz, is created when trivalent aluminum ions and pentavalent phosphorus ions replace some silicon ions within the quartz crystal lattice. This partial replacement renders the lattice susceptible to distortion from the energy of natural geophysical radiation, creating color centers that form when radiation displaces phosphorus ions from their normal lattice positions, leaving voids that trap electrons. When white light boosts these trapped electrons to higher energy levels, they return to their normal levels by releasing excess energy as visible light that we perceive as pink or pale red.
Pink Quartz vs. Rose Quartz
The inclusions in massive rose quartz inhibit crystal development, while the absence of inclusions in pink quartz ensures normal crystal development and a high degree of transparency. In addition, the color of pink quartz is often zoned and most intense near the crystal terminations. The color of crystalline pink quartz also fades slowly with prolonged exposure to sunlight, while the color of massive rose quartz is stable. And pink quartz is sometimes intermixed with citrine, the golden-yellow color variety of quartz.
The formation of pink quartz requires unusual and complex chemical and physical conditions that include partial ionic replacement within the quartz lattice, sufficient geophysical radiation to create color centers, and enough space to permit crystal growth. Because these conditions don’t often occur together, pink quartz, unlike rose quartz, is rare, costly, and found in only a few localities.
Another difference between the rose and pink subvarieties is size. Rose quartz often occurs in large masses; pink quartz is found only as crystals an inch or two in size. Given these collective differences, the term pink quartz is now used to differentiate crystalline pink quartz from massive rose quartz.
In general usage, the descriptive color terms pink and rose are often imprecise. Rose quartz is sometimes sold as pink quartz and vice versa. Also, massive rose quartz is frequently cut into hexagonal prisms for use in pendants; while these may appear to be natural crystals of pink quartz, their translucency immediately identifies them as rose quartz. Pink quartz is almost always retained as a specimen in its natural form.

Metaphysical Properties of Pink Quartz
Pink and Rose Quartz are similar in that they promote calm, help alleviate stress and anxiety and provide a soothing ambiance to any environment. They bring a relaxed, cooperative atmosphere to the workplace and family relationships. They work well to aid in meditation and connecting with the emotional body. Pink Quartz also acts as a protective crystal in dream work and is especially good for those experiencing nightmares and night terrors.
Pink Quartz is not only a crystal of identity; it also strengthens those faced with a loss of identity or recovering after a trauma. Pink Quartz protects the ego while the heat mends. Pink Quartz brings comfort and connects you to universal love, helping re-establish or redefine who you are, reinstate trust, and emerge stronger, more assured, and self-reliant.
