Jade is a beautiful stone that can be many different colors including green, orange, or white. Most of us will have seen the Jade that is green in color. Jade however is a very popular and expensive stone and this has given rise to many fakes, imitations or treated Jades being seen in the market place. Ancient records show that the Chinese started to dye jade to improve the color in 13th century. If you are about to go shopping for jade or have an old piece of jade, here is an article that will help you tell if you have found the real thing.

If you have to upgrade to a business account, so be it. Better than losing out on deals. Or having your hard earned money frozen in the account. Finally, have a plan for management. Do you have a good bank roll and plan on buying a large number of authentic sneakers before selling? Are you planning to buy shoes and then flip them quickly?
Because real money is printed on linen and cotton paper, the ink remains clear or slightly yellow. If a bill is printed on wood-based paper, the ink reacts and turns dark. Some pens come with a coil cord so you can keep them attached to your cash register. Tests For: Correct paper.

Tests and Observations

Irregularities mean it’s probably real

Consumers are the real losers from counterfeit currency. We look at your rights, as well as how you can spot a potential fake Take note: there are more than 700,000 fakes in circulation.

Hold it up to a bright light. If possible, examine the internal structure with a X10 Loupe. Can you see little fibrous or granular, felt-like, asbestos-like intertwinings? If so, it’s probably genuine nephrite or jadeite. Chrysoprase, which is commonly used an imitation, is microcrystalline, so it will look homogenous.If you see anything resembling layers with the 10X loupe, you’re probably looking at jadeite that’s been “doubled” or even “tripled” (thin layer of gem-quality jadeite sometimes glued over a different base).

Check The Density Of Jade

A specific density gravity test can be performed as described below, or you can judge the density less accurately by tossing the stone in the air and catching it in your palm. If it feels heavier than most stone pieces of the same size, it is more likely to be authentic jade.

Another way to judge density is to observe the sound of plastic beads gently tapping each other. If you have a piece of real jade, clink it against the stone in question. If it sounds like plastic beads, then the stone in question is probably fake.

Both jadeite and nephrite have a very high density (jadeite - 3.3; nephrite - 2.95). Density is measured by dividing the weight (in grams) by the volume (c.c.).

Cold Test

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. However, this is very subjective, and most helpful when you can compare it to real jade of a similar shape and size.

Perform A Scratch Test

Jadeite is very hard; it will scratch glass or even metal. Nephrite, however, can be much softer, so performing a scratch test improperly may damage a genuine piece. Use the blunt end of a pair of scissors and gently press down and draw a line on an area on the jade piece that is not visible (bottom or end of the piece). Avoid any weathering surfaces because these are much softer and can be easily damaged. If the scratch makes a white line, gently wipe it off (it might be metal residue from the scissors). Is there still a scratch? If so, it’s probably not authentic jade.

If it scratches glass or steel, it could still be many of the alternatives to jade as well, including the various forms of green quartz and prehnite.

Perform this test at your own risk. The piece may be very valuable, even if it’s not made from jade, and can lose significant value if scratched.

Even if you have real jade in your hands, it can still be treated by dyeing, bleaching, use of stabilizing polymers, and creating jade doublets and triplets. Jade is divided into three categories based on these possibilities:

Type A - natural, untreated, undergoes a traditional process (plum juice washing and polishing with beeswax), no “artificial treatments” (e.g. high temperature or high-pressure treatments), “true” color.
Type B - Chemically bleached to remove impurities, injected with polymer with the use of a centrifuge to enhance translucency, covered with hard and clear plastic like coating, subject to instability and discoloration over time because polymer gets broken down by heat or household detergent, still 100% real jade with 100% natural color.
Type C - chemically bleached, dyed to enhance color, subject to discoloration over time due to reaction with strong light, body heat or household detergent.

Become Familiar With Imitation Jade

Jadeite and Nephrite Jade are genuine Jade. In New Zealand, Greenstone or Pounamuis highly regarded by Maori. Maori people recognize four main types of pounamu, identifying their color and translucence: kawakawa, kahurangi, Ä«nanga. These are all nephrite. They also regard a fourth type of pounamu - tangiwai- from Milford Sound which, although prized is actually bowenite and not truly jade in the eyes of the rest of the world.

Other materials passed off as jade include:

Aventurine Quartz
Malaysia Jade (permanently dyed translucent quartz that may be called by its color – Red Jade, Yellow Jade, Blue Jade)
Opaque Dolomite Marble (“Mountain Jade” - from Asia, dyed in vibrant colors)

Practical Guide To Doing A Density Test

Equipment Needed -

spring scale (100 gram, 500 gram, or 2500 gram, depending on the weight of the piece(s) you’re testing)
bucket, big enough for you to dip your piece(s) of jade in
strings
pony tail holder
rubber bands
paper towel (to dry items)

Instructions -

Use crocodile clamps to grasp the jade item. If the scale doesn’t come with crocodile clamps, wrap the tested jade with a piece of string, a rubber band or a pony tail holder.
Lift the spring scale by its top handle and write down the weight of the jade item in air. (Note this should be a scale based on grams and therefore measuring force in dynes - c.g.s system)
Gently place the jade item completely into the water bucket and write down its weight in water. The clamp can touch the water; it shouldn’t significantly affect the weight. If you’re concerned, however, use one of the alternatives described above. Since the test is based on the difference in weight, as long as the string, band or pony tail holder remains on the jade both in the air and in the water, the difference will be the same.
Calculate the volume of jade item: weight in air then divide by 1000 (or 981 if you have a calculator handy) minus weight in water divided by 1000 (or 981 if you have a calculator handy). This gives the mass in grams in air and the apparent mass in water. Subtract the in water value from the air value, this gives you the volume in cc.
Calculate the density of the jade item: mass in air divided by volume. Jadeite has a density of 3.20-3.33 g/cc, while nephrite has a density of 2.98 - 3.33 g/cc.
