Heating and Amethyst to a temperature between 57.2 and 75.2 degrees F can turn the Amethyst from violet to golden yellow and from Amethyst to a jewel of citrine. When heat treating a single amethyst jewel, the color can change from warm orange to light green prasiolite, also known as green Amethyst.

In these cases, the crystal can receive a treatment or enhancement to produce more color. The crystal may not be as vibrant as desired. However, this is not the intended result. In some cases, a jeweler can apply heat treatment to the Amethyst and saturate the gemstone with a deep purple tint. The enhancement of existing beloved amethyst tones is entirely natural. The growth process penetrates the Amethyst when exposed to natural radiation and transforms it into a vibrant purple hue. Natural Amethyst ColorsĪmethyst colors gets its beautiful violet color from the presence of iron impurities in the crystal quartz structure. Although it is a popular gem, there are very few violet crystals I have bought. For those looking for a saturated purple stone, there are several violet shades in its spectrum.

This numbers should be somewhere in the 2.65 range if you have real amethyst. To find specific gravity, divide the weight of the amethyst by the weight of the displaced water. This is the weight of the displaced water. Subtract the beaker's original weight from this number.

Weigh the beaker again, with the displaced water in it.

Put in the amount of water that the mineral displaced.

Remove the amethyst and drain the water.

Subtract the level the water is at now from its original level. Then, partially fill the beaker with water and write down the amount of water, as measured by the beaker. Then, write down the weight of the amethyst.

To start, write down the weight of the beaker.

X Research source You can measure specific gravity with a beaker, big enough to fit your piece of amethyst in, and a scale. For amethyst, specific gravity should be around 2.65. Specific gravity is a term used by jeweler's to ascertain the rough density of a gem.
