Rose quartz's color is caused by iron and titanium impurities

Hardstone carving is one of the oldest arts in China, dating back to the fifth millennium B.C

Brazil is also the only current source of true well-formed crystals of rose quartz. Rose quartz was once believed to be only massive, found primarily in the cores of pegmatites. This lack of crystals is somewhat of a curiosity because quartz crystallizes into well-formed crystals in all its other macroscopic varieties. So amazing are the rose quartz crystals that the first ones discovered were dismissed as fakes by mineralogists from around the world.

The color is caused by iron and titanium impurities. If rutile needles are present in the rose quartz then a star effect or asterism is sometimes seen. The star is best seen when light is viewed through the rose quartz. This is different from asterisms in most other gemstones, such as ruby and sapphire, where the stars are seen when light is shown on the gems. Rose quartz is only one of several quartz varieties. Other varieties that form macroscopic (large enough to see) crystals are as follows:

• Amethyst is the purple gemstone variety.
• Citrine is a yellow to orange gemstone variety that is rare in nature but is often created by heating Amethyst.
• Milky Quartz is the cloudy white variety.
• Prasiolite is the leek-green variety.
• Rock crystal is the clear variety that is also used as a gemstone.
• Smoky quartz is the brown to gray variety.
