It is worth bearing in mind that each 12mm gemstone beads has its own individual shape and color. In the original mineral, there are a variety of fractions. We can say that there are no two similar 12mm gemstone beads. In some minerals, this is especially pronounced (agate, jasper, carnelian, sodalite, snow obsidian).
Many 12mm faceted gemstone beads used in the manufacture of jewelry are subjected to additional coloring. This does not reduce their properties at all and does not make them less natural, but only gives the necessary shade.
For example, some 12mm matte gemstone beads can be found very rarely. Jade is painted in all sorts of colors, even completely unnatural for natural faceted stone, for example, in red and blue.
Lapis lazuli 12mm matte gemstone beads (lapis lazuli) and so contains a very strong coloring pigment, which has long been used in wall paintings and also obtained from it the ultramarine paint, highly appreciated by artists. They painted the heavens and the blue robes of the Virgin Mary, where it symbolized purity and purity. This explains the inherent property of natural lapis lazuli to leave blue marks on the skin. But in some cases, natural lapis lazuli, which does not contain enough blue pigment, is indeed additionally colored. Painted faceted stone looks no different from unpainted.
