It contains more alloys then gold so.

Carat purity is measured as 24 times the pure mass divided by the total mass:

where is the carat rating of the material,
is the mass of pure gold or platinum in the material, and
is the total mass of the material.
Therefore, 24-Carat gold is fine (actually 99.9% gold by mass rather than 100%), 18-Carat gold is 18 parts gold 6 parts another metal (forming an alloy with 75% gold), 12-Carat gold is 12 parts gold (12 parts another metal), and so forth.
In England, the carat was divisible into four grains, and the grain was divisible into four quarts. For example, a gold alloy of fineness (that is, 99.2% purity) could have been described as being 23-carat, 3-grain, 1-quart gold.
The Carat system is increasingly being complemented or superseded by the millesimal fineness system, in which the purity of precious metals is denoted by parts per thousand of pure metal in the alloy; e.g. 18-carat gold, 75% Au, would be called 750..

Carat conversion:

58.33% - 62.50% = 14k (acclaimed 58.33%)
75.00% - 79.16% = 18k (acclaimed 75.00%)
91.66% - 95.83% = 22k (acclaimed 91.66%)
95.83% - 99.95% = 23k (acclaimed 95.83%)
99.95 and above = 24k (acclaimed 99.99%)

Hope that answers your question :smokin

The only difference is your pockets feel better but thats all
 
879 grams is still a lot even for 10k lol, but yea id rather go smaller and at least get it 14k

How can y'all tell that's 10k?

"The value of gold is based on the karat system, which is a 24-point scale signifying the percentage of gold a piece of metal contains.

So, if gold jewelry is 14K, it is 14 out of 24 parts gold, or 58.33 percent gold.

The acid test is the cheapest method used to check gold. Simple acid test kits typically come with a black touchstone and several acid solutions, which are marked for different karats.

Experts start by scratching the touchstone using the gold that needs to be tested, leaving a streak on the stone. If the questionable gold is purportedly 14K, they will then make a parallel control streak using a piece of gold that is already known to be 14K.

Finally, they'll put a drop of the acid solution on both streaks and compare the ensuing chemical reactions.

Jewelers may also use electronic gold testers to figure out the quality of a piece of gold. Using a specific liquid or gel, they first create a circuit between the device's probe and the gold.

The device then tests the gold's electrical conductivity — this property not only tells the jeweler if the material is actually gold, but also its purity. Electronic gold testers are fairly accurate when used properly (they must be fully cleaned of the gel in between uses).

The most accurate tests use X-ray fluorescence spectrometers (XRF). These machines, which can cost thousands of dollars, send X-rays through the tested item.

The material's atoms become momentarily excited and move into a higher energy state; when they return to their ground state, they release radiation, which the XRF detects and reads.

By analyzing the radiation, the machine figures out exactly what the item is made of."

"The first thing to do to check if you have real gold is to look at it. Look for particular signs that point to real gold.

1

Inspect the piece for official markings. A stamp will indicate either fineness (1-999 or .1-.999) or karat (10K, 14K, 18K, 22K or 24K). A magnifying glass will make this easier.

An older piece might not have a visible marking due to wear.
Counterfeit pieces can often have a marking that appears authentic; more testing may be needed either way.

2

Look for noticeable discoloration. It is important to check for discoloration in areas that face constant friction (typically around the edges).

If the gold seems to be wearing off and showing a different metal beneath it, you probably have a piece that is only gold plated.
Bite Test

We have all seen a movie where a prospector bites down on a piece of gold to test it. We also see Olympic athletes bite on their “gold” medal when they receive it. Whether that is of any use is another story altogether.

3

Bite down on your gold with moderate pressure.

Examine your gold for any markings. In theory, real gold will show indents from your teeth; deeper markings indicate purer gold.

This is actually not a recommended test, as you can damage your teeth. Not to mention that lead is even softer than gold and gold-plated lead will appear to be gold when you bite it.

4

Magnet Test

This is an easy test, but it’s not an all-encompassing or fool-proof way to determine whether your gold is real. Something as weak as a fridge magnet will not be useful, but stronger magnets that you can find in specialized hardware stores or in common objects such as women’s purse latches, children’s toys, or even in old unused hard drives will be strong enough to perform this test.

Hold a magnet up to the item. Gold is not a magnetic metal, so if it pulls towards, or sticks to the magnet, it’s fake. However, just because it doesn’t react to the magnet doesn’t mean it is real, as non-magnetic metals are used in counterfeit pieces as well.

5

Density Test

There are very few metals denser than gold. The density of pure 24K gold is about 19.3 g/ml, which is much higher than most other metals. Measuring the density of your items can help you determine if your gold is real. As a rule of thumb, the higher the density, the purer the gold. Make sure to perform the density test on gold that has no gemstones of any kind attached. See the warnings below for important information about the density test.

Weigh your piece of gold. A jeweler can normally do this for you for free if you don’t have your own scale. You will need the weight in grams.

6

Fill a vial with water.
It’s helpful if the vial has millimeter markings on the side, since that will make it easier for you to read the measurements for this test.
It doesn’t matter how much water you use as long as you don’t fill the vial to the top, since the water level will rise once you immerse the gold in it.
It’s also important to note the exact amount of the water level before and after immersion.

Place your gold in the vial. Take note of the new water level and calculate the difference between those two numbers in millilitres.

Use the following formula to calculate density: Density = mass/volume displacement. A result close to 19 g/ml indicates either real gold, or a material with a density similar to gold. Here is an example calculation:
Your gold item weighs 38 g and it displaces 2 milliliters of water. Using the formula of [mass (38 g)]/[volume displacement (2 ml)], your result would be 19 g/ml, which is very close to the density of gold.
Bear in mind that different gold purity will have a different g/ml ratio:
14K – 12.9 to 14.6 g/ml
18K yellow – 15.2 to 15.9 g/ml
18K white – 14.7 to 16.9 g/ml
22K – 17.7 to 17.8 g/ml"

Less than 50% pure gold? Should it still be considered a gold chain? Srs question.

Yes it is, 10 parts Gold 14 parts Alloy, 41.66% Gold, 58.34% Alloys if I'm correct in the UK they actually sell 9K, what type of **** is that!? :x :smh: |I not even legally classified as gold in the USA, 9 parts Gold 15 parts Alloy, 37.5% Gold 62.5% Allloys |I

It's quality over quantity. Why buy 800+ grams of trash 10K when he could have got a 200+ gram 14K-18K Cuban hand made from Daniels. Lame |I

"What we are referring to is a version of the legendary Rolex Daytona that happens to feature a face made out of 100% real meteorite. Gibeon Meteorite, to be exact. Gibeon Meteorite fell to earth approximately 12,000 years ago (although who knows how accurate that is), and was discovered in 1836 in a rural part of Namibia. The total fall is estimated at 26000 KG, however much of it is now protected under Namibian law and can not leave the country. Gibeon meteorites are made of an iron-nickel alloy, but contain also cobalt and phosphorous. It has been dated to be about 4billion years old, and while it's not exactly rare, Rolex has been able to secure some of the finest, most striking pieces of it."

The chemical composition of the Gibeon is:
90% iron
8% nickel
0.4% cobalt
0.04% phosphorus.
The minerals in the Gibeon are:

Kamacite, taenite make up 99%+ of the meteorite
Troilite (an iron sulfide) is common as nodules and in recrystallized forms.
Chromite (chrome oxide) is found occasionally
Daubreelite is found in the kamacite.
Enstatite (a silicate mineral--pyroxene) is rare.
Tridymite (a silicate mineral) is rare.
