February birthstone is Amethyst. Amethyst is a beautiful purple quartz. All amethyst are quartz but not all quartz are amethyst :) did you know that if you leave the amethyst in direct sunlight it will start to loose it’s purple color and start turning more clear and white. Almost all amethysts present in the market today have been artificially treated. This is done to effectively enhance their color and to improve the overall clarity. To do this, the amethyst is usually exposed to extreme heat in a controlled environment. In most cases, it is treated at a temperature of 400-500 degrees Celsius.
That said, when placed in direct and extreme light, the stone could fade and lose its color over a period of time. This mainly happens due to particle physics. Essentially when a photon from a secondary source like sunlight, for example, hits an atom, one of two things can happen:
If the atom is color-neutral, the photon either gets absorbed as heat or get reflected. This reflection can’t be seen by the human eye as the photon is colorless.
If the atom is color-charged, on the other hand, the photon will enter the atom and push out the color-charged particles (also known as a quark). When this process is experienced repeatedly, the atom eventually starts to run out of quarks which leads to the fading of the substance as a whole.
In this particular case, the amethyst contains color-charged atoms which is why it will fade when exposed to extreme light. The fading of the amethyst stone is considered normal and will happen if it is repeatedly exposed to sunlight. #rubigoesrogue #amethyst #mineralogy #crystals #quartz #knowledgeshare Photos used for the slide, credit: https://www.bernardine.com/types-of-amethyst/
