I've recently heard that most Rose Quartz on the market has been dyed and that true Rose Quartz is more colorless/white. Can you please clarify that for me? Is any of the Rose Quartz rough pieces that you sell dyed? How about orange calcite that has a very vivid tangerine/citrus orange color?
There are a variety of Rose Quartz specimens that are various shades of pink that are not dyed. One source states that the color is caused by iron and titanium inclusions. Another research site indicates that the color of much Rose Quartz may be due to microscopic inclusions of a fibrous mineral, such as Dumortierite or a related species.
Many times, the color is determined by the Rose Quartz's location and mineral content in the area. For instance, Lavender Rose Quartz has inclusions of Lithium that change it from the rosy pink we are more familiar with, to lavender and lilac hues.
So truly, Rose Quartz can be almost white, pink /white, rose, dark rose, lavender and all hues in between.
The only time I have seen Rose Quartz appear darker or more intense than it really is, is when bead vendors string Rose Quartz beads on dark pink or red string to enhance the color. The beads are not dyed, just enhanced via the color of the thread/string.
To our knowledge, all of the Rose Quartz and Calcite we carry are 100% natural.
As far as the Orange Calcite - from my understanding - all Calcites are natural and can be quite intense in color. The orange calcite, as you mentioned, as well as the bright, intense Emerald greens are particularly vivid. The wide variety of colors depends on the inclusion of minor impurities in the location where the calcite is grown.
I do not believe any calcite needs to be dyed to further enhance its color since they are already so intense and the color is consistent throughout. With dyed pieces, you will see bands, splotches, specific areas of color, but the color is not consistent. Also, Calcite is pretty soft material, so I am not sure it could even take the coloring process.
I hope this helps to clarify a bit. Great questions!
