Charoite is translucent lavender to purple in color with a pearly luster. Charoite is strictly massive in nature, and fractures are conchoidal.It has an unusual swirling, fibrous appearance, sometimes chatoyant, and that, along with its intense color, can lead many to believe at first that it is synthetic or enhanced artificially.
Hexagonite is pleochroic, potentially displaying varying shades of blue, violet, purple, or red. [1] It is also known as "mangan-tremolite", since the manganese imparts the mineral's unique colors. [citation needed] Pink, lilac, and purple are the most common colors. [1] Hexagonite has been successfully faceted. [1]
It is a mixture of amethyst and citrine with zones of purple and yellow or orange. Almost all commercially available ametrine is mined in Bolivia. The colour of the zones visible within ametrine are due to differing oxidation states of iron within the crystal. The citrine segments have oxidized iron while the amethyst segments are unoxidized.
Citrine “A powerful gemstone crystal in a range of deep yellows, oranges, and yellow-cream-white, the citrine gemstone is said to bring abundance and wealth into one’s life,” Salzer says.
Amethyst frequently shows color zoning, with the most intense color typically found at the crystal terminations. One of gem cutters' tasks is to make a finished product with even color. Sometimes, only a thin layer of a natural, uncut amethyst is violet colored, or the color is very uneven.
As a result of this phenomenon, a multitude of colors have been observed in various specimens: shades of purple, violet, indigo, blue, cyan, green, yellow, orange, red and brown. After heating, tanzanite becomes dichroic. The dichroic colours range from violet through bluish-violet to indigo and violetish-blue to blue. [29]
Kunzite is a purple-colored gemstone, a variety of spodumene, with the color coming from minor to trace amounts of manganese. Exposure to sunlight can fade its color. [22] Kunzite was discovered in 1902, and was named after George Frederick Kunz, Tiffany & Co's chief jeweler at the time, and a noted mineralogist. [22]
