Why does green jade turn black? The intensity of the colour of Jade will only change due to dirt or grease that can sometimes get trapped on the surface, or if the Jade piece has undergone colour treatment, gradually fading to its original state as time passes.
Thankfully, the truth about natural, untreated jadeite jade is that it will in fact not change color over time. Natural jade is impervious to perfumes, oils, and most cold acids.
Injury, Diseases Causing Spots on Jade Plant
More frequently, when a jade plant has black spots it is due to excessive humidity and overwatering in winter. Jade plants go into dormancy when light levels are low and do not actively grow in winter. Reducing water in winter is important to maintaining jade plant health.
Nevertheless, B jade is still real jade and has fully natural colour. This jade variety is known as flower green because the base is pea green and the patches of black inclusions look like flowers. Pea varieties have opaque green and white round spots that look like snow peas.
Add lukewarm water to a dish large enough to hold your jade piece. Mix in two or three drops of mild, alcohol-free dish or hand soap until totally dissolved. Soak your jade piece in the solution-filled dish for up to one minute. Gently scrub the object with a delicate brush or your fingers.
Real jade should be cold to the touch and have a dense, solid feel. Fake jade is often made from materials such as glass or plastic which are not as dense as real jade. If the stone feels light or hollow, it is likely that it is fake.
Symptoms of jade plant root rot include yellowing or wilting leaves, brown or blackened roots, and sudden death of the plant. If you think your jade plant has root rot, the first thing you should do is check the roots. If they are brown or black, this is a sure sign of root rot.
The finest-quality jadeite—almost transparent with a vibrant emerald-green color—is known as “Imperial jade.” The royal court of China once had a standing order for all available material of this kind, and it's one of the world's most expensive gems.
In some cultures, wearing jade is a big deal – and not always in a good way.

The most valuable jade color is known as “imperial jade” and occurs only in jadeite. Imperial jade is a green balanced between blue and yellow hues. The ideal tone is medium-dark, about 75%, where green hues are optimally saturated.
The term 'jade' is actually a catch-all term that encompasses two separate minerals: nephrite, which is more opaque and traditionally used for sculptural objects and ornaments; and jadeite, which is more translucent and can be polished to a high lustre, making it more suitable for jewellery.
Green Jade: The Most Iconic Jade Color
The most valuable green jade, also known as “imperial jade,” exhibits a vibrant emerald hue. Green jade is often associated with luck, abundance, and prosperity, as well as emotional and spiritual benefits such as wisdom, balance, and calm.
Checking the Color and Texture
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. If it looks like there are air bubbles in the stone, then it's likely not real.
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.
Symptoms. Jade plants with leaves turning yellow, brown or translucent with a soft feel to the leaves often with a drooping appearance. Brown spots on leaves.
Root rot is practically incurable and most plants will not survive it. In the case of the jade plant, however, you may propagate the plant but cutting healthy leaves off and rooting them, to save at least part of the plant.
Jade is not only known for its spiritual virtues, but it is also appreciated for its hardness. This can be tested by scratching the surface with a knife, if the blade leaves no trace, it is jade. However, if a scratch appears, it indicates a softer stone such as serpentine or chrysolite.
Materials often mistaken for jade include chrysoprase, maw sit sit, serpentine, hydrogrossular garnet and aventurine. This is due to these gemstones boasting the same deep green colour that jade is most famous for, though each have subtle differences that allow you to identify their true nature.
Some poor-quality variations can be worth only $2 per carat. However, the value rises with the variation, place of origin, texture, and much more, so you may be able to pay as much as $3 million per carat. If you want to buy or sell jade per gram, keep in mind that the price goes from $25 to $5,000.
If you find a so-called "synthetic jade" for sale, you're probably looking at a lookalike or simulant. These are gem materials that may resemble natural jadeite or nephrite but are neither. These can range from glass pieces to natural gemstones of other species, such as serpentine or prehnite, or even assembled stones.
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.
