When buying jade, we often see such ornaments - a pendant or jade on the two colors of each other, and the jade carvings use the two colors properly, carved into a vivid pattern, making the entire jade life, full of vitality. Then, how is the phenomenon of jade and two colors coexisting?
Our common two-color coexistence mainly includes white-green and yellow-red. Now let's take a closer look at how white-green and yellow-red colors are formed.
Why are some of the same jadeites white and some green? The original green part of the jade is caused by the coloring elements chromium and iron. The colored ions of iron and chromium replace the colorless aluminum ions. The iron ions are often light green, the chromium ions will show very bright green, and the high-grade green is Due to the formation of chromium ions. But if there is too much chrome, the green of the jade will become too thick and look like black, but the value will be much lower. Due to the different proportions of chromium and iron, jadeite will present a variety of different greens, with pure emerald green, yellowish, bluish, and grayish green, and different green values.
Yellow and red
Both yellow and red jade are called "翡", that is, "黄翡" and "红翡". Yellow and red, except for the large cracks along the emerald, are usually found in the outer skin of the jadeite. The appearance of the jadeite material is formed by oxidation. The coloring ions are iron ions, and the iron ions are oxidized to become ferric iron. Red, yellow. However, one thing to note when buying red jade is that you should not treat the burnt red scorpion as a natural red scorpion. Some red is burnt later. This red color is often unnatural and the seeds are thicker. This is the color formed by heating after adding limonite.
