The soft translucence and pale pink to deep pink shades of rose quartz appeal to gem lovers as well as crystal collectors.

Color
Rose quartz gets its name from its delicate pink color, ranging from very light pink (almost white) to medium-dark pink.

Deep pink shades are very popular for rose quartz, but they’re rare in small sizes. This gem displays noticeable color zoning.
It’s not uncommon to see some quartz varieties with color zoning. This rose quartz exhibits rich purple-pink areas of color.
Clarity
Tiny inclusions are responsible for the translucent appearance of most rose quartz. Finest-quality rose quartz is often transparent, so it’s usually faceted.

Microscopic, fibrous mineral inclusions can cause a cloudy appearance, even in fine-quality faceted rose quartz. - Robert Weldon

Cut
The inclusions in rose quartz can create a display of asterism when the gem is cut as a cabochon. It might also be faceted or fashioned into beads.

Carat Weight
Rose quartz is available in sizes large enough to inspire gem designers and carvers. Fashioned gems in larger sizes often display more intense color.
