Amethyst Gemstone Guide

An Introduction to Amethyst

Amethyst exhibits a striking violet color range from light lilac to deep purple with red undertones, making it immensely popular due to its unique tones. The darker shades of purple are particularly coveted for their desirability. Amethyst’s color variations are caused by different imperfections within the quartz, created when iron replaces silicone in the crystal structure during the irradiation process.

Primarily associated with jagged clusters and geodes, amethyst has gained popularity in jewelry in recent years. It is the birthstone for February and is relatively affordable compared to other gemstones.

Amethyst Durability

With a Mohs scale rating of 7, amethyst is quite durable and suitable for daily wear. It is commonly used in more casual jewelry pieces, but it can also be found in engagement rings for those who prefer amethyst over other gems.

Amethyst Shapes and Cuts

When purchasing amethyst, raw geodes or clusters with spikes and peaks are common shapes. In jewelry, the oval cut, a variation of the round brilliant cut, is most frequently used. Additionally, amethyst can be found in various other cuts to suit individual preferences.

The oval cut enhances the appearance of amethyst by making it look larger and highlighting its beauty when light interacts with the stone, especially showcasing its purple hue.

Amethyst Sizes

Amethyst is available in a range of sizes and shapes, with some of the largest specimens reaching impressive dimensions. The availability of high-quality amethyst in larger sizes sets it apart from other gemstones.

Amethyst Colors

The most sought-after shade of amethyst is the darker, deeper purple known as Siberian Amethyst, valued for its richness and quality. It is essential to carefully inspect amethyst for visible color zoning, ensuring a saturated dark purple with reddish hues without appearing too dark.

While deep purple is preferred for quality and value, brightness is also crucial. Avoid amethyst so dark that it appears black, aiming for a stone that shines vividly even in dim lighting.

Amethyst Clarity

Most amethysts are considered eye-clean, indicating that imperfections are not easily visible to the naked eye. While inclusions may be present, they typically do not detract significantly from the stone’s appearance.

Color holds more value than flaws in amethyst, emphasizing the significance of a well-colored stone over a flawless yet off-color one.

Amethyst Sourcing

Naturally occurring amethyst is primarily mined in Siberia, known for its vibrant purple tones. Other significant producing countries include Sri Lanka, Brazil, and Uruguay. Exceptional amethyst varieties have also been sourced from African countries such as Zambia, Tanzania, and Namibia.

While amethyst is generally accessible, high-grade amethyst like “Deep Siberian” remains rare and valuable, depending on collector demand.

Amethyst Certification

While not always certified, it is advisable to seek certification when purchasing any gemstone, with the Gemological Institute of America (GIA) being a reputable organization for this purpose.

Lab-grown amethysts, though less common, possess uniform characteristics and lack the unique imperfections of naturally occurring amethyst. Transparency from jewelers about sourcing and certification is essential for buyers.

Amethyst Treatments

Amethyst often undergoes treatments such as heat treatment and irradiation to enhance its color and clarity, common practices in the gemstone industry. These treatments aim to improve the stone’s appearance without compromising its natural properties.

Grading Amethysts

Amethyst grading lacks a standardized system but typically revolves around color quality. Grades like AA, AAA, and AAAA are used to classify amethyst based on color and clarity levels, with AAAA often associated with fine jewelry.
