Question & Answer:-

 Why is gold so popular?

Ans:

Gold has been popular for millennia for its brilliant shine. The fact that it does not corrode, tarnish or rust is great too. It is a rare element and its price reflects that. Being a soft metal, it is also easy to work with.

 

 

 Why is gold alloyed so often?

 Ans:

Mixing gold with other metals makes it harder, cheaper and different colors depending on what other metals are used.

 

 

 What is a Karat?

 Ans:

 Not to be confused with “carat,” “karat” refers to the purity of the gold. 24K (karat) gold is 99.999% pure gold. 18K is 18/24 or 75% gold and 25% other metals.

 

 

Which is better, 18K or 14K gold?

 Ans:

Neither is better than the other. 18K gold is more expensive due to the higher gold content. Because it has more gold, it is more yellow. However, the extra gold also makes it softer. A setting made with 14K gold will hold stones a little better because the 58.333% of other metals stiffens it. Ultimately, it comes down to your personal taste

 

 

 My item does not have a gold karat stamp. Is this real gold? How many karats is it?

 Ans:

Your item is real gold. Its karatage is stated on the item description. If the karat stamp happened to be on the portion that was removed when your item was resized, the karat stamp will be missing. The stamp could also be missing if the manufacturer of the item rushes manufacturing and skips the stamping process.

 

 

 How do I know that my jewelry is made with real gold ?

 Ans:

There are some tests you can perform on the gold to test it. First being a visual inspection.
When you look at the gold, are there any black, silver or other color blotches in it? When you hold the gold item, does it feel heavy? Has the karatage been stamped on it? The following table will show you the common locations of the karatage stamp.
Another test you can do is the acid test. Gold is the only yellow metal that does not react with nitric acid. 10K gold or less may react to this test due to the low gold content. Test kits are available at jewelry supply stores. The test usually involves rubbing a miniscule amount of the metal on the supplied paper and putting a drop of the acid on the paper rubbings. If the color does not change, it is real gold.
A third test you can do is the price test. If the price is too good to be true, it probably is. To figure out the value of your gold, you need to know the current market value for gold, the gold ounce weight and its karatage. The value can be calculated as:
value = (weight in ounces) x (gold market value) x (karatage/24)
For example, if the price of gold is $900 per ounce, and you are looking at a 22K gold pendant that weighs 1/4 ounces, the formula would be:
value = (1/4) x ($900.00) x (22/24) =
value = (0.25) x ($900.00) x (91.667) = $206.25
The price can be higher for workmanship or branding, but if the asking price is $100, you can be sure that the pendant is not 18K gold or even real gold.

 

 

 How is colored gold made?

 Ans:

24K gold is yellow and yellow only. Gold can be mixed with other metals to create other colors. The following chart shows what combinations of other metals are used to create the different colors of gold.
 Bright Yellow 18K 75% gold 15.5% copper 9.5% silver
 Bright Yellow 14K 58.5% gold      29% copper 12.5% silver
 White* 14K 58.3% gold 23.5% copper 12.2% nickel 5.97% zinc
 Deep Green   75% gold 25% silver  
 Deep Pink   75% gold 25% copper  
 Deep Pink   75% gold 25% aluminum  
 Blue**   75% gold 25% iron  
 Black** 58.3% gold 41.7% iron
 Purple**   70.5% gold 5% tin 1.5% thorium

* White gold is often coated with Rhodium to mask any yellow tints.
** These are hard to work with and are rarely found in jewelry.

 

 

 What is platinum?

 Ans:

Platinum is a relatively new precious metal to the jewelry field compared with gold. The qualities of platinum are similar to gold in that it will not corrode, tarnish or rust. However, platinum is very hard compared to gold and silver. It is usually mixed with iridium which makes it difficult to work with.

 

 

 Why is platinum so expensive?

 Ans:

Platinum is expensive because it is rarer than gold. It is also heavier than gold, making jewelry of the same size weigh more. It is also more difficult to work with due to its high melting point and rapid setting. Annually, only about 133 tons of platinum are mined, compared to 1,782 tons of gold.

 

 

 Other metals are mentioned when discussing settings. What are they and  what are they used for?

 Ans:

The other metals used with jewelry are:

Rhodium

Used to plate white gold and platinum to give it a more silvery appearance.

Iridium   

This is alloyed with platinum to make it harder.

Palladium

Items are alloyed with this inexpensive and lightweight to reduce cost.

Ruthenium

This is occasionally alloyed with platinum to make it harder.

Osmium

This is the hardest known metal and is rarely used in jewelry.
