Purple Agate vs Amethyst – How To Tell The Difference?

In order to understand the difference between these two stones, we can look at the color, shape, pattern, clarity, and more. Below we’ll describe all these aspects in detail.

Chemical Composition 

The purple agate stone belongs to the chalcedony quartz mineral family, which is a microcrystalline form of quartz. This means that you can only see the crystal structure when using a microscope.

The mineral composition of purple agate is mainly silica and other trace elements. Its structure is amorphous, meaning it cannot be identified by a standard shape. The reason for this is that they are formed in cavities where volcanic activity has taken place. Note though, that agate are often sold as slices.

Amethyst is a popular purple stone from the quartz family of minerals. The stone is a silicate that consists of silicon dioxide.

Both stones are purple, but amethyst generally has a softer purple color than agate.

Agates occur in a variety of colors.  Besides purple, also referred to as violet agate, the stone is available in green, yellow, blue, brown, and gray. The purple variety receives its color from the iron and manganese that is present in the stone. Natural purple agate often receives treatments in order to enhance the color.

Amethyst often comes in an attractive purple color, which varies from light to dark hues, but can also be found in pink, black or yellow. The latter is also referred to as citrine. Purple amethyst may show red or blue secondary hues when observed under a source of light.

The purple color on amethyst stones results from irradiation of iron trace elements present in the stone during crystallization. The color zoning effect, meaning the color is distributed unevenly, is caused by the amounts of iron incorporated into the crystals in different stages of growth. The darker the purple shade, the more iron. The color zoning on amethyst affects its price in the market. Uniform coloration is valuable and most desirable.

Pattern and Clarity

Purple agate is translucent to opaque, whereas amethyst is translucent to transparent. Additionally, amethyst’s shine is glass-like, while agate is waxier.

In terms of pattern, agate is known for having banding formations. For purple agate, the bands can be different shades of purple as well as white. Amethyst can have some color variations within the stone and perhaps some colorless streaks as well.

This agate stone breaks at an uneven fracture, meaning that the surface of a broken off agate is rough and irregular. On the other hand, amethyst breaks at a conchoidal fracture, which means the surface of the fracture is curved. You’ll often find this type of fracture in glass as well.

Purple agate and amethyst both rate 7 on the Mohs scale.

If you’re unfamiliar, the Mohs scale of hardness determines a stone’s hardness by measuring how scratch-resistant it is. According to this scale, a stone can scratch any other mineral with a lower score. For reference, talc is a 1, whereas diamond is a 10.

With both scoring a 7, this means they are durable stones that can be worn daily and can be used in jewelry, carvings, and ornaments.


Purple agate originated and was first used in Egypt and other ancient civilizations. The stone in the modern day can be found in Australia, Morocco, Brazil, and Mexico. 

Amethyst forms in igneous, metamorphic, and sedimentary rocks. Most of the mineral comes from Canada, Morocco, Myanmar, and Mexico. Amethyst geodes are found in Brazil. 


Care should be taken when handling and storing these stones to prevent damage. 

We recommend cleaning your stones by either running them under tap water or cleaning them with a damp cloth. If you’d like, you can use some detergent as well. Make sure to dry the stones afterward. Although it won’t cause immediate problems, we never recommend leaving stones to soak, as this can turn them dull or brittle.

Apart from physically cleaning the stones, you might want to clear them from negative energies. This is highly recommended if you used them for their metaphysical properties.

The reason for this is that these stones absorb low vibrations. Every month or so, you want to remove these energies from the stone so you can continue to use it. After cleansing, it is recommended you also recharge the stones to make sure they are full of positive energy to share with you.

Purple agate and amethyst can be cleansed and recharged by moonlight or using cleansing crystals like selenite and clear quartz. The stones can also be left in clean salty water for a few minutes to tune it to its original vibration, but again, beware that this may cause damage in the long term.

We do not recommend leaving amethyst in the sun, as they are likely to fade when exposed to direct sunlight for longer periods.

In physical healing, amethyst stones help with hormonal imbalances, and digestive system problems and boost immunity. Amethyst is also believed to relieve headaches and improve the skin’s appearance.

This is probably the most common way to make the most out of the benefits of these stones all day. It is made into pendants, necklaces, bracelets, rings, and earrings. These pieces can be worn as accessories and also as talismans for protection and fortune.
