Identifying Real Amethyst: The Basics

Understanding Amethyst

Amethyst is a semi-precious stone that has been valued for centuries for its stunning purple hue and unique physical properties. It is a type of quartz that gets its color from irradiation, which causes the crystal structure to absorb specific wavelengths of light and reflect others. This gives amethyst its characteristic purple color, which can range from a light lavender to a deep, rich violet.

Origins and Occurrence

Amethyst is found in a variety of geographic locations around the world, including Brazil, Uruguay, and Mexico. It is often found in geodes or veins in volcanic rocks, and can also be found in ancient fossilized wood.

Physical Properties

Amethyst is a relatively hard stone, with a hardness of 7 on the Mohs scale. It has a cubic crystal structure and a vitreous luster. It is also relatively dense, with a specific gravity of 2.65.

Color and Clarity

The color of amethyst is the most distinctive and valuable characteristic of the stone. The color should be a pure, deep purple with no visible inclusions or cloudiness. The clarity of the stone should also be excellent, with no visible internal flaws or imperfections.

It is important to note that amethyst can be treated or enhanced in a variety of ways, including heat treatment, irradiation, and dyeing. These treatments can improve the color and clarity of the stone, but they can also decrease its value and authenticity. It is important to be aware of these treatments and to carefully examine the stone before making a purchase.

Authenticity Features to Look For

Growth Patterns

When examining the growth patterns of an amethyst, one of the key indicators of authenticity is the presence of parallel growth lines, known as growth lines or crystal lines. These lines are formed as the crystal grows in a directional manner, with each line representing a period of growth. The angle between these lines can provide clues about the temperature and pressure conditions during the crystal’s formation.

Additionally, amethyst often exhibits a characteristic known as “doubling,” where the crystal structure displays a repeating pattern of six-sided stars. This feature is particularly prominent in larger crystals and is another sign of authenticity.

Inclusions and Surface Textures

Amethysts can contain inclusions, which are small particles or crystals trapped inside the gemstone during its formation. These inclusions can be valuable in determining the authenticity of an amethyst, as some types of inclusions are unique to the stone. For example, amethyst can contain needle-like inclusions of another mineral, such as iron or manganese, which can be seen with the aid of a magnifying lens.

Surface textures can also provide clues about the authenticity of an amethyst. Natural amethysts often have a slightly rough, pitted surface caused by irregularities in the crystal structure. This texture can be compared to the surface of a wine glass, with a series of small bumps and ridges. Artificial amethysts, on the other hand, may have a smoother surface due to the manufacturing process.

Geode Shapes and Crystal Formations

When examining an amethyst geode, pay attention to the shape and formation of the crystals. Natural amethyst geodes often have a distinct, layered appearance, with multiple layers of crystals stacked on top of one another. The layers can be visible to the naked eye or require magnification to see. In contrast, artificial amethyst geodes may have a more uniform appearance, with the crystals appearing to be more tightly packed together.

Additionally, natural amethysts can exhibit a unique crystal formation known as “amethyst quartz,” which is characterized by a distinct, six-sided shape with pyramidal ends. This formation can be seen on both individual crystals and on the surface of a geode. Artificial amethysts may not exhibit this specific crystal formation.

Assessing Amethyst with Tests and Tools

The Lorelei Quartz Cluster Test

Method

The Lorelei Quartz Cluster Test is a method used to determine the authenticity of amethyst by observing the reaction of the quartz cluster to the presence of the amethyst stone.

Procedure

1. Obtain a Lorelei quartz cluster and an amethyst stone.
2. Place the amethyst stone in close proximity to the Lorelei quartz cluster.
3. Observe the cluster for any visible reactions or changes in color, shape, or size.
4. Record the observations and compare them to known authentic reactions.

Interpretation

The interpretation of the Lorelei Quartz Cluster Test involves comparing the observed reactions to known authentic reactions of the quartz cluster. If the amethyst stone is genuine, it should elicit a distinct reaction from the quartz cluster. The presence of this reaction indicates that the amethyst is likely authentic. However, if no reaction is observed, the amethyst may be a fake or imitation.

The Hardness Test

The hardness test is a method of assessing the authenticity of amethyst by determining its hardness using a specialized device called a refractometer. The refractometer measures the refractive index of the amethyst, which is an indicator of its hardness.

To conduct the hardness test, the amethyst is cleaned and polished to remove any dirt or residue. The refractometer is then used to measure the refractive index of the amethyst at different angles. The readings are compared to a reference chart to determine the hardness of the amethyst.

The hardness test is a reliable method of determining the authenticity of amethyst. The refractive index of natural amethyst is typically between 1.54 and 1.56, while synthetic amethyst has a refractive index of around 1.51. Therefore, if the refractive index of the amethyst being tested falls within the range of natural amethyst, it is likely to be authentic. However, if the refractive index is lower than that of natural amethyst, it is likely that the amethyst is synthetic. It is important to note that while the hardness test is a useful tool for assessing the authenticity of amethyst, it should be used in conjunction with other tests and visual inspections to ensure accurate results.

The Refractive Index Test

The refractive index test is a method used to determine the authenticity of amethyst by measuring the degree to which the stone refracts light. This test is based on the principle that different materials have different refractive indices, which is the ratio of the speed of light in a vacuum to the speed of light in the material.

To conduct the refractive index test, a device called a refractometer is used. The refractometer measures the angle of refraction of light passing through the amethyst stone. The refractive index of amethyst is 1.544, which is slightly higher than that of quartz (1.54).

To begin the test, the amethyst stone is cleaned and polished to remove any dirt or impurities. The refractometer is then placed on top of the stone, and the angle of refraction is measured. The test is conducted twice, once with the stone in its natural state and once with the stone treated with a special solution.

The results of the refractive index test are compared to the known refractive index of amethyst. If the measured refractive index falls within the range of 1.544, the amethyst is considered authentic. However, if the measured refractive index falls outside this range, the amethyst may be a fake or a treated stone.

It is important to note that while the refractive index test is a reliable method for determining the authenticity of amethyst, it is not foolproof. Some treated stones may have a refractive index that falls within the range of natural amethyst, making it difficult to distinguish between the two. Therefore, it is recommended to use the refractive index test in conjunction with other tests and tools to ensure the authenticity of the amethyst stone.
