Low-quality jade often looks dull, opaque, or has an unnaturally uniform color, lacking the deep, inner glow and slight translucency of fine jade, frequently appearing cloudy, rough, or showing signs of chemical treatment like dyed streaks or a "plastic" look, with poor texture, weak sound, and excessive bubbles or flaws indicating it's likely glass or imitation. It feels lighter, lacks the dense weight of real jade, and may deteriorate or discolor over time.
The first step when trying to identify whether your jade gemstone is genuine or not is assessing its texture. Jade comes in many different colors but should never be opaque or dull. A lackluster texture means it's not authentic jade and could have been dyed with chemicals.
Modern Jade Grading System - This system is used by some jade dealers and divides jade into ten grades, with Grade 1 being the highest quality and Grade 10 being the lowest. This system takes into account color, translucency, texture, and other factors to determine the quality of the stone.
Transparency and Texture
Transparency greatly affects jadeite's price. Semi-transparent to transparent jadeite is valued much higher than opaque varieties. Similarly, a smooth, even texture without impurities or cracks can significantly increase a jade's value.
They check its level of transparency. They look for even coloration or a pleasing mottling of colors. They also look for fine polish and undistorted surface reflections. Clarity is important, too, because any fractures can strongly affect value.
For jadeite, the intensity of the green color, combined with a high degree of translucency are the key factors in judging value. Stones which are too dark in color or not so translucent are less highly valued. Ideally, color should be completely even to the unaided eye, without spotting or veins.
Shine the UV light directly onto the surface, keeping the flashlight steady for consistent results. Note the presence or absence of fluorescence, its intensity, and its color. Check for cracks, inclusions, and other irregularities. Use reference materials or trusted guides to interpret your findings accurately.
Hold the piece of jade in your hand. It should feel “cold, smooth and soap like to the touch”. It should take a while to get warm if it is real.
Value: Type A jadeite is the most prized and valuable grade due to its natural state and durability. High- quality Type A pieces, especially those with vibrant "imperial green" hues, can fetch astronomical prices. Usage: Primarily used in high-end jewelry such as bangles, pendants, and rings.
“Fluorescence” occurs when jade emits a glow under ultraviolet or specific light sources. This effect is influenced by trace elements likechromium (Cr) and iron (Fe) within the jade. Naturally fluorescent jade may display scattered, dotted, or patchy patterns under light.
Green Jade has been synonymous with good luck for centuries. Considered a highly protective stone, Green Jade has been incorporated into weapons and jewellery and used by many to promote healing. Today, it is incorporated most commonly into jewellery items and is thought to bring the wearer good luck and fortune.
Serpentine is the name for many types of stones and they all resemble jade. Serpentine is waxy, green stone which is not as smooth as jade but is sometimes mistaken for jade. Chrysoprase imitates jade's two forms, too. Jade can be mistaken for green quartz or prehnite.
Price depends on quality of the jade piece individually, for example the yellow ring could have a starting price of 90 usd and it only goes up from there depending on the translucency and quality.
The idea is that a hair will burn only on treated jade, not on real jade. But as you'll see, this test doesn't hold up. Both real and treated jade stay cool under heat—just like glass. And, of course, if you hold the lighter to the hair long enough, it will still burn regardless of what it's wrapped around.
Some highly translucent pieces may have a faint glow but a genuine piece of jadeite does not emit light in the dark or fluoresce under Ultraviolet (UV) light. A chemically bleached piece of jade can exude a pale blue-white glow under long-wave UV light.
All you need is your phone flashlight to check if your jadeite might be chemically bleached (B jade). Hold the jade up to a strong phone light. Look through the structure under the beam. Not “ice texture”—this is chemical damage exposed.
What to look for:
Fluorescence happens when certain elements and crystal defects inside a gem get “excited” by ultraviolet rays and respond by glowing in vibrant colors, such as blue, green, or even red. It's like a gemstone's private light show! But fluorescence isn't just beautiful.
Because it's a combination of opaque and transparent, look for a shine that's similar to light reflecting off water. If the color is dull or flat, it's likely a fake stone. Jade can sometimes be totally opaque, but the opaque stones aren't very valuable.
