Today Xiaobian saw a kind of jade in the nearby small jade market. At first it was thought to be Bi Moyu, and the last boss said it was black sapphire. Black Sapphire Xiaobian knows very little, so today I collected some simple knowledge about what is black sapphire on the Internet. I hope that friends who know me less can add more knowledge!

What is black sapphire

Black sapphire It is a kind of sapphire in Hetian jade. Under the strong light flashlight, the black cyan reveals the cyan light. Under natural light, the best black sapphire looks pure black. In addition to black blue, the pure black Hetian jade also includes black and black jade. The black pebbles in the jasper are green or blue. Pure black in the jade, light through the white light. It is not jade that is not opaque, and the ink jade that is black and then ink will also transmit light. The chemical composition and physical properties of black sapphire are both with Hetian jade. akin.

Black sapphire features

The appearance of black sapphire is similar to that of blue ink, and it is also black as varnish. The difference is that black sapphire is transparent.

It exhibits a deep blue hue, while the translucent translucent light shows a brilliant green color. The reason is that the green tone of black sapphire is colored by iron, the color is generally gray, and the chrome is chrome (the same reason as the green color of jade), the color is bright green. In addition to the light-transparent color, the appearance density of black sapphire blue ink is also different. The density of the blue ink is stronger, it looks dense, and the black-green looks more water-permeable. The third difference is that black and blue generally have no black spots. Under the sun and under the blue light, it will show a blue-green color, while in the darker light, it is black, while the blue ink is black under the sunlight or a strong light source. The transmitted light will show a green tone. It can be seen that black sapphire is a special variety of Hetian jade and not a blue ink, so it does not belong to the category of ink jade. Shown in Figure 1 is the dark cyan light that appears after the black sapphire material is transmitted through the light.

The above is the simple knowledge collected by Xiaobian about what is black sapphire. I hope that I can help the friends of Aiyu to learn more about jade species again, and hope that they can help you make correct when purchasing similar jade. Judgment!
