Amethyst, a beautiful purple quartz, is cherished for its stunning hue and calming energy. However, with the increasing popularity of this gemstone, the market has seen a rise in fake amethyst jewelry. If you own an amethyst bracelet and want to ensure its authenticity, this comprehensive guide will help you distinguish between genuine and fake amethyst.
Understanding Amethyst
Before delving into the methods of determining authenticity, it’s essential to understand what amethyst is. Amethyst is a variety of quartz that is typically purple, ranging from light lavender to deep violet. The color is due to the presence of iron impurities and natural irradiation.
The Significance of Amethyst
Amethyst is more than just a pretty stone. Historically, it has been associated with numerous properties:
Spiritual: Believed to provide spiritual protection and purification.
Healing: Known for its ability to promote calm, balance, and peace.
Physical: Thought to help with physical ailments, particularly those related to the nervous system.
Knowing these attributes, it’s easy to see why genuine amethyst is highly sought after.
Visual Inspection
One of the first steps in identifying the authenticity of your amethyst bracelet is through a visual inspection. This involves examining the color, clarity, and cut of the stones.
Color
Authentic Amethyst Color:
Consistent Hue: Genuine amethyst has a consistent color throughout the stone, though it may display zoning (color bands or areas of different shades). The color should be a range of light to dark purple.
Natural Variations: Look for natural color variations, which indicate authenticity. These variations are often subtle and blend well.
Fake Amethyst Color:
Uniformity: Fake amethysts may have a perfectly uniform color with no zoning or variation.
Artificial Tints: Some fakes are dyed quartz or glass, which can result in overly vibrant or unnaturally consistent colors.
Clarity and Inclusions
Authentic Amethyst Clarity:
Inclusions: Genuine amethyst often has inclusions or tiny imperfections. These can be small air bubbles, other minerals, or natural fractures within the stone.
Moderate Clarity: While high-quality amethyst is relatively clear, perfect clarity is rare and can be a sign of synthetic or treated stones.
Fake Amethyst Clarity:
Perfect Clarity: If the stone is perfectly clear with no inclusions, it could be synthetic.
Visible Bubbles: If you notice bubbles that resemble those in glass, the stone is likely not real.
Cut and Shape
Authentic Amethyst Cut:
Precision: Genuine amethyst is often cut with precision to enhance its natural beauty.
Variety: Authentic stones come in various shapes and cuts, reflecting their natural crystal structure.
Fake Amethyst Cut:
Poor Craftsmanship: Fake stones may have uneven or poorly executed cuts.
Uniformity: Fakes are often mass-produced and may exhibit uniform shapes and cuts.
Physical Properties
Beyond visual inspection, you can examine the physical properties of the amethyst to determine authenticity.
Hardness
Mohs Hardness Scale:
Amethyst ranks 7 on the Mohs hardness scale, meaning it can scratch glass and is relatively resistant to scratching by objects of lower hardness.
Testing Hardness:
Scratch Test: Gently scratch the surface of a piece of glass with the amethyst. If it leaves a scratch, it is likely genuine.
Fingernail Test: Your fingernail cannot scratch genuine amethyst. If it does, the stone is likely fake.
Density and Weight
Density:
Genuine amethyst has a specific gravity of 2.65. This means it should feel slightly heavier than similar-sized stones or glass.
Weight Comparison:
Balance Test: Compare the weight of your amethyst bracelet to a similar-sized bracelet made of glass or plastic. Genuine amethyst should feel heavier.
Water Test: Submerge the bracelet in water. Real amethyst should sink due to its higher density, while some fakes might float or not sink as quickly.
Advanced Testing Methods
If visual and physical inspections are inconclusive, advanced testing methods can provide more definitive results.
UV Light Test
Ultraviolet Light Reaction:
Genuine amethyst may exhibit weak fluorescence under UV light, often appearing a faint green or red.
How to Perform the UV Test:
Get a UV Light Source: Use a small UV flashlight or lamp.
Observe the Reaction: Place the amethyst under the UV light and observe any fluorescence. If it glows brightly or with unusual colors, it might be synthetic or treated.
Heat Test
Heat Resistance:
Genuine amethyst can withstand moderate heat without significant changes. Fake stones, especially those made of glass or plastic, may discolor or crack.

Conducting a Heat Test:
Use a Lighter: Gently heat the stone with a lighter for a few seconds.
Observe Changes: Genuine amethyst will remain unchanged. If the stone shows signs of discoloration or cracking, it is likely fake.

Common Fake Amethyst Materials
Understanding the materials often used to create fake amethyst can help in identification.
Glass
Appearance:
Glass fakes often have perfect clarity and uniform color, lacking the natural inclusions of real amethyst.
Identification:
Look for bubbles and a lighter weight compared to genuine amethyst.
Dyed Quartz
Appearance:
Dyed quartz can mimic the color of amethyst but often has unnaturally bright or uniform colors.
Identification:
Scratching the surface may reveal the underlying color if the dye has not penetrated deeply.
Synthetic Amethyst
Appearance:
Synthetic amethyst can be very similar in appearance to natural amethyst but often lacks natural inclusions.
Identification:
Professional testing is usually required to distinguish synthetic amethyst from natural stones.

Ask for Certification
Request a certificate of authenticity from a recognized gemological laboratory.
Educate Yourself
Educate yourself on the characteristics of genuine amethyst and common fakes.
Inspect Before Buying
Examine the amethyst for color, clarity, cut, and other physical properties before purchasing.
Conclusion
Determining the authenticity of your amethyst bracelet requires careful inspection and, in some cases, professional testing. By understanding the visual and physical characteristics of genuine amethyst, as well as common materials used for fakes, you can make informed decisions and enjoy the beauty and benefits of this stunning gemstone with confidence.
