In ancient times, the quest for genuine jade was a matter of both prestige and practicality. Jade has become increasingly popular not only for its beauty but also for its supposed protective and healing properties.
According to a report by the International Gem Society (IGS), the global market for jade jewelry is incredibly lucrative, with high-quality jadeite reaching prices of up to $3,000 per carat.
With a variety of jade jewelry available anywhere, sometimes, it’s all too easy to end up with a piece that’s less “royal heirloom” and more “plastic trinket.” Read on our guide to help you learn more about jade so you can better determine the genuine jade from the fake ones.
Understanding Jade: Nephrite vs. Jadeite
First things first: not all jade is created equal. It comes in two main varieties: nephrite and jadeite.
Nephrite comes in a range of colors, from translucent white (known as “mutton fat jade”) to various shades of green, and even brown and black. Its durability and the ease with which it can be carved make it a favorite for intricate designs and everyday wear.
It is often used in oriental jade jewelry, including traditional amulets, bangles, and ceremonial pieces. The easiest way to distinguish a nephrite jewelry is to look for a smooth, silky texture with a slightly fibrous structure. Nephrite is tough and resistant to breaking, making it ideal for robust jewelry pieces.
Jadeite, on the other hand, is prized for its vibrant colors, including the highly coveted imperial green. However, jadeite also comes in a stunning array of colors such as lavender (often referred to as jade jewelry purple), red, yellow, and even blue. The translucency and vivid colors of jadeite make it the preferred choice for high-end jewelry.
It is frequently used in luxurious gold jade jewelry, where it is set in gold to enhance its natural beauty. The easiest way to distinguish it from nephrite is its glassy, smooth surface and a higher degree of translucency. Due to its rarity and vibrant colors, jadeite is considered more valuable and is often featured in exclusive collections like those by Mason-Kay jade jewelry.
Knowing which type of jade you’re dealing with is crucial, as it influences both the value and the authenticity tests. And it is essential especially for anyone interested in purchasing or collecting authentic jade jewelry. Whether you’re drawn to the rich history and durability of nephrite or the vibrant, high-value jadeite, knowing what to look for ensures you make an informed decision.
The Color Test: Hue, Saturation, and Distribution
When it comes to jade, color is king—or queen, if you prefer. Genuine jadeite is prized for its rich, vibrant green color. Here’s what to look for:
– Hue: True jade has a natural, consistent hue. For jadeite, the most prized hue is a rich, emerald green known as “imperial green.” Nephrite often appears in more subdued greens, cream, or even dark brown and black. Genuine jade doesn’t have an artificially enhanced color. If the hue looks too perfect or unnaturally vibrant, it might be dyed or treated. Natural jade has a balanced, organic look to its color.
– Saturation: Authentic jade should have evenly saturated color. This means that the color is distributed uniformly throughout the stone without any streaks or patches. Uneven saturation can indicate lower quality or artificial enhancement. Whether it’s the lush green of jadeite or the creamy white of nephrite, the saturation should be pleasing to the eye and consistent across the piece.
– Distribution: Natural jade often exhibits subtle variations in color distribution. These variations are a hallmark of genuine jade and add to its unique beauty. Perfectly uniform color might suggest that the stone has been dyed. Look for natural inclusions and patterns that indicate authenticity. These can include slight color shifts, fibrous textures, or other natural features that give the jade character.
Always examine jade under natural light to get the most accurate sense of its color. Artificial lighting can sometimes distort the true hue and saturation.
The Texture Test: Smoothness and Grain
Texture is another critical aspect when it comes to identifying genuine jade jewelry. The feel and appearance of jade’s surface can provide significant clues about its authenticity. Genuine jade has a smooth, even texture, but it’s not entirely without character. Here’s how to check:
– Smoothness: Authentic jade feels exceptionally smooth to the touch, almost like silk. This smoothness comes from jade’s fine-grained structure and high polish. When you run your fingers over a genuine piece of jade, it should feel luxurious and sleek, not rough or gritty.
While genuine jade is smooth, it has a slight resistance when you move your fingers across it. This subtle drag is a hallmark of real jade, contrasting with the overly slick feel of some artificial materials like glass or plastic. The slight resistance gives jade a unique tactile quality that enhances its appeal.
– Grain: Look closely at the surface of the jade. Genuine jade often displays fine, fibrous grains or interlocking crystal structures. These grains are natural inclusions that occur as the jade forms over millions of years. The presence of these fibers is a good indicator of authenticity.
Natural jade may have small inclusions or imperfections that add to its character. These can include tiny mineral deposits, slight variations in texture, or other natural features that give each piece a unique identity. Perfectly flawless jade with no grain or inclusions might be a sign of synthetic or treated stone.
You can also use a jeweler’s loupe or a magnifying glass to examine the surface of the jade closely. Look for the fine, fibrous grains that are characteristic of natural jade. Or you can try running your fingers gently over the jade’s surface. Authentic jade should feel smooth but with that slight resistance that sets it apart from fakes.
The Transparency Test: Translucence and Clarity
Genuine jade possesses a unique glow when light passes through it, a characteristic that can be assessed through the transparency test. Here’s how to evaluate translucence and clarity to ensure your jade is the real deal:
– Translucence: When you hold genuine jade up to the light, it allows some light to pass through, creating a soft, almost ethereal glow. This translucence is especially notable in high-quality jadeite, which can exhibit a glassy, semi-transparent appearance.
– Clarity: Genuine jade can have natural inclusions or imperfections, such as tiny mineral deposits or fibrous structures. These inclusions are part of jade’s natural formation process and add to its character. However, they should not dominate the stone’s appearance.
While genuine jade should not be overly opaque, it also shouldn’t be completely clear like glass. The ideal jade has a balance, where it is translucent enough to exhibit that inner glow but still has some degree of opacity due to natural inclusions.
Conduct the transparency test in natural light to observe the true characteristics of the jade. Artificial light can sometimes mask or alter the appearance of translucence and clarity.
Hold the jade piece up to a light source, such as a window or a lamp. Observe how the light interacts with the stone, looking for that soft, inner glow and even light distribution.
The Sound Test: The Ring of Real Jade
Yes, you read that right. Real jade sings. Well, not exactly, but it does produce a distinctive sound. Here’s how to perform the sound test and what to listen for:
– The Ring: When you gently tap genuine jade with another piece of jade or a metal object, it produces a clear, resonant sound. This sound is often described as musical or bell-like. The clarity and resonance of the sound are due to jade’s dense, compact structure, which allows it to transmit vibrations effectively.
Imitation jade or jade-like materials, such as glass or plastic, often produce a dull, flat sound when tapped. This lack of resonance and the absence of a clear tone can help you identify these less valuable or synthetic materials.
For the most accurate results, use a metal object, like a small hammer or a metal rod, to tap the jade. This will provide a clear, distinct sound that can help you determine authenticity.
If you have another piece of jade, you can tap the two pieces together. Genuine jade pieces will produce a harmonious, ringing sound when struck.
The Scratch Test: Hardness and Durability
Jade is tough—seriously tough. In fact, it’s one of the hardest gemstones out there. It can withstand significant wear and tear, making it a reliable choice for fine jewelry. Here’s how to use the scratch test to assess the hardness and durability of your jade:
– Hardness: Jade is known for its impressive hardness. On the Mohs scale of mineral hardness, jadeite ranks between 6 and 7, while nephrite is slightly softer but still quite hard. This high level of hardness means that jade is resistant to scratching and can endure daily use without significant damage.
If the jade scratches easily or shows visible damage from the test, it’s a strong indication that the stone is not genuine. Many imitations, such as glass or plastic, have much lower hardness and will show scratches readily.
For a reliable test, use a steel object with a known hardness, such as a steel nail or a metal tool. Avoid using objects that might damage the jade more than necessary.
Gently scratch the jade with minimal pressure to avoid damaging the stone. The goal is to test the hardness without inflicting unnecessary harm.
The Temperature Test: Cool to the Touch
One of jade’s most unique features is its coolness to the touch, which can be a handy test. The temperature test is a fascinating way to assess the authenticity of jade, leveraging one of its most distinctive physical properties.
Genuine jade has a unique thermal characteristic that sets it apart from many imitation materials. Here’s a closer look at how to use the temperature test to determine whether your jade is authentic:
– Coolness: Genuine jade remains noticeably cool to the touch, even after being held for a while. This is due to jade’s dense, compact structure, which has a high thermal mass. The stone absorbs heat slowly and releases it at a slow rate, maintaining a cool feeling against your skin.
The coolness is not merely a surface feature; it reflects the stone’s thermal inertia. Unlike materials with lower density or poor thermal conductivity, jade doesn’t quickly warm up to body temperature, maintaining its cool sensation for a longer time.
If the jade becomes warm or loses its cool feeling soon after handling, it may be an indication that the material is not authentic. Genuine jade should maintain its coolness for a significant period.
This test is applicable to any piece of natural jade, including jade bangles, jade jewelry bracelets, pendants, and rings. By assessing how the jade responds to your touch, you can determine whether it retains its characteristic coolness, which is a key indicator of genuine jade.
