Test gemstone real or fake with tool diamond selector II ,diamond selector II ,tesgemstone
Sure, I can help you with that. A diamond selector II is a device that can test the thermal conductivity of a gemstone to determine if it is a real diamond or not². Here are the steps to use it¹:
1. Set the volume or sensitivity. Turn the knob on the selector marked volume to activate it. You should hear a beep and see a light come on.
2. Uncap the selector. Take the rubber cap off the tip of the selector gently. The cap protects the tip so be careful not to damage it.
3. Test the gemstone. Place the tip of the selector on the gemstone at a right angle. Press it firmly but gently until you hear another beep or see the light change color.
4. Interpret the result. If the light changes to green or red quickly, it means the gemstone is a diamond. If the light stays yellow or changes slowly, it means the gemstone is not a diamond.

Amethyst is a purple variety of quartz that is often used as a gemstone¹. You can test it with a diamond selector II by following the same steps as for testing a diamond²:
1. Set the volume or sensitivity. Turn the knob on the selector marked volume to activate it. You should hear a beep and see a light come on.
2. Uncap the selector. Take the rubber cap off the tip of the selector gently. The cap protects the tip so be careful not to damage it.
3. Test the amethyst. Place the tip of the selector on the amethyst at a right angle. Press it firmly but gently until you hear another beep or see the light change color.
4. Interpret the result. If the light changes to green or red quickly, it means the amethyst is a diamond. If the light stays yellow or changes slowly, it means the amethyst is not a diamond.

Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.[2][3][4] The hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry.
Hue and tone
Green quartz is sometimes incorrectly called green amethyst, which is a misnomer and not an appropriate name for the material, the proper terminology being prasiolite.[8] Other names for green quartz are vermarine or lime citrine.[citation needed]
Amethyst frequently shows color zoning, with the most intense color typically found at the crystal terminations. One of a gem cutter’s 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. The uncut gem may have only a small portion that’s suitable for faceting.[9][10]
The color of amethyst has been demonstrated to result from substitution by irradiation of trivalent iron (Fe3+) for silicon in the structure,[4][11] in the presence of trace elements of large ionic radius,[3] and, to a certain extent, the amethyst color can naturally result from displacement of transition elements even if the iron concentration is low. Natural amethyst is dichroic in reddish violet and bluish violet,[4] but when heated, turns yellow-orange, yellow-brown, or dark brownish and may resemble citrine,[12] but loses its dichroism, unlike genuine citrine. When partially heated, amethyst can result in ametrine.
