Rose quartz is a type of quartz that exhibits a pale pink to rose red hue. The color is usually considered as due to trace amounts of [[titanium]], [[iron]], or [[manganese]] in the material. Some rose quartz contains microscopic [[rutile]] needles that produce [[Asterism (gemology)|asterism]] in transmitted light. Recent [[X-ray crystallography|X-ray diffraction]] studies suggest that the color is due to thin microscopic fibers of possibly [[dumortierite]] within the quartz.<ref>{{cite web |url=http://www.mindat.org/show.php?id=3456 |title=Rose Quartz |archive-url=https://web.archive.org/web/20090401031656/http://www.mindat.org/show.php?id=3456 |archive-date=1 April 2009 |website=Mindat.org |url-status=live |access-date=11 May 2023}}</ref>

Additionally, there is a rare type of pink quartz (also frequently called crystalline rose quartz) with color that is thought to be caused by trace amounts of [[phosphate]] or [[aluminium]]. The color in crystals is apparently photosensitive and subject to fading. The first crystals were found in a [[pegmatite]] found near [[Rumford, Maine|Rumford]], [[Maine]], US, and in [[Minas Gerais]], Brazil.<ref>{{cite web |url=http://minerals.caltech.edu/ge114/Lecture_Topics/Quartz/Index.htm |url-status=dead |title=Quartz and its colored varieties |archive-url=https://web.archive.org/web/20110719160220/http://minerals.caltech.edu/ge114/Lecture_Topics/Quartz/Index.htm |archive-date=19 July 2011 |publisher=California Institute of Technology}}</ref> The crystals found are more transparent and euhedral, due to the impurities of phosphate and aluminium that formed crystalline rose quartz, unlike the [[iron]] and microscopic [[dumortierite]] fibers that formed rose quartz.<ref>{{cite web |url=http://www.quartzpage.de/pink.html |title=Pink Quartz |website=The Quartz Page |access-date=11 May 2023}}</ref>
