An
amethyst diamond engagement ring is a popular pick among people who prefer a pop of violet shade in their
diamond ring. Amethyst belongs to the quartz family, is made of silicon dioxide, and has a hardness of 7/10 on the Mohs’ scale that makes it relatively hard.
The color of
amethyst stone is due to the presence of impurities in the crystal structure and it comes in shades of violet. The primary color is purple, however, it can have secondary colors like blue and red too, that can be either very much pronounced or virtually invisible.
Amethyst stones having primary color alone are pricier than those with secondary hues. Lighter stones usually have pinkish tone while darker ones will have a deep purple hue. Generally, darker colors are more expensive; the best grade for amethyst is “Deep Siberian”, which has an intense purple tone.
Jewelers sometimes treat amethyst with heat for enhancing its color intensity. In addition, heat treatments are often used to produce more colors like brown, orange, and yellow hues. This treatment can even be employed to turn
amethyst into a yellow citrine. Therefore, while shopping for an
amethyst diamond engagement ring, you need to ask the
jeweler whether the stone is enhanced. In addition, it is advisable to get a
diamond certificate that ensures the quality of the stone.
