There has been plenty of debate over the elements that are responsible for the color of a rose quartz. While mineralogical literature attributes titanium, manganese, and iron for its hue, other sources claim that it is actually caused due to microscopic inclusions of dumortierite — an aluminium boro-silicate mineral.
As with almost all gems, cutting and polishing can significantly alter the depth of color in a rose quartz. A highly polished version of this stone can look translucent and even transparent in some cases.
The translucent appearance of most rose quartz stones can be attributed to tiny inclusions. When polished, these inclusions (depending on their position and size) will actually enhance the beauty of the gem. Large surface cracks, however, bring down the value significantly as they can affect the stone’s durability and the way it reflects light.
Rose quartz is normally cut into cabochons and beads. Translucent rough is also used for carving dainty and whimsical figurines.
Certain specimens of this gem include a dense network of fine inclusions that align with the hexagonal crystal structure. When a cabochon is cut in a certain way, the base becomes perpendicular to the c-axis of the quartz crystal. This may result in asterism in the form of a six-ray star.
Rose quartz that is extremely transparent will be faceted for use in jewelry. Round, oval, pear and cushion are some of the most common shapes in which this gem is available. Its delicate color is often intensified by cutting the stone in larger sizes.
