2. Inclusions Inclusions of a second mineral (or even air!) within a host mineral can also alter a mineral's color. Examples: Prase quartz: Hedenbergite inclusions in quartz give prase its green color. Green quartz: Chlorite inclusions in quartz also cause it to turn green. Jasper: Hematite inclusions can turn jasper red. Milky quartz: Inclusions of very small air bubbles in clear quartz turn ...

Rose Quartz is a very affordable gemstone. Due to its often hazy color and frequent flaws, it is more often tumbled or used as beads over faceting into gemstone cuts. A deeper pink color in Rose Quartz makes it less common and more desirable, though certain forms of Rose Quartz may fade upon repeated prolonged exposure to strong lighting.
