Gold Jewelry

Gold is measured in units called karats. 10K, 14K and 18K signifies fine jewelry: the higher the karat, the greater the gold content. Watch out for words like real gold or real silver in advertisements. Often, businesses will use these words to dupe the buyer. Costume and fashion jewelry contain very small amounts of real gold. Beware of the word overlay even if it is precedes the 10, 14 or 18K designation. This refers to a process of bonding and it designates costume or fashion jewelry.

Wholesale Silver Jewelry

Silver costs less than gold but it tarnishes easily. When searching for silver jewelry, you’ll want to know the difference between fine or sterling silver and silver-plated. Sterling silver has a content of 92.5 percent silver and 7.5 percent copper and will be stamped or labeled "925" or "Steer." Jewelry that is not tagged Sterling Silver, is most likely cast in brass or zinc then

hand-dipped in silver. Sterling Silver pieces are more costly and considered fine jewelry.

Wholesale Fashion Jewelry

Fashion Jewelry contains real gold and silver electroplated over brass or Sterling Silver. The measurement of gold, in terms of quality, is defined by the amount of mils, a unit of measurement referencing the quantity of precious metal in the number of layers that is used in the overlay; the higher the mils, the higher the quality and the price. The jewels used in fashion jewelry are semi-precious stones, lab created gemstones, crystals and rhinestones, and they all have quality and cost classifications of their own. Like fine jewelry, the same terminology applies: facet, referring to the cut; clarity, referring to the brilliance; and fire, referring to the kaleidoscope of colors. Austrian Swarovski crystals, higher in quality than plain crystals, are considered superior to rhinestones because they are more intricately faceted and have higher light diffraction or fire.

It is common for fashion jewelry to carry the name of a famous designer or a celebrity. When buying designer or celebrity wholesale jewelry, always check the current season’s retail line. Outdated retail lines command less money in both the retail and wholesale market. Researching the current retail market value will help in determining the value of wholesale price.

Wholesale Costume Jewelry

Costume Jewelry is cheaper than Fashion Jewelry in both quality and price. Usually made of plastic or acrylic, it’s often termed junk jewelry and is sold in deep discount or dollar stores. If costume jewelry claims any gold, it is gold plated, not electroplated. The gold or silver is thinner and in addition to the base metal being different - pewter, nickel and sometimes lead - the overlay itself is often not pure gold or sliver. Thus, it commands a much cheaper price

in both retail and wholesale markets. Gold plated and electroplated are not the same.

Body Jewelry

Jewelry adornments such as belly button studs, brow and nose rings have become trendy and are in high demand, particularly with the younger crowd. When piercing the body, the higher quality jewelry is often the better choice. Many people have allergic reactions to metals so it is important to know the metal content of any jewelry you purchase.

A good thing to keep in mind is that trendy jewelry will often see a higher ratio of bogus dealers trying to make fast money in a high-demand market. Often, they misrepresent the jewelry to the uneducated buyer. An internet search will undoubtedly turn up several hundred sites that offer jewelry at wholesale prices, but if you are not keen on buying online, look in your local directory

for discount and wholesale dealers in your area.

You might also want to attend jewelry or designer’s trade show or visit a local flea market where you can actually see the jewelry and assess the quality. While it’s okay to order online and from catalogs, make certain there is a return policy.

Finally, look for reputable dealers who have an established track record. Don’t be shy about asking for customer testimonies that you can verify. Whether you’re buying for your personal collection or for resale, buying wholesale jewelry can save your bank account.

Gold Karats facts you must know about karat gold before making your next purchase

There are many different types of gold available from regular jewelry stores and online jewellery stores in Australia and around the world. Understanding the difference will help you make a better informed decision when purchasing your next piece of fine karat gold jewelry.


Gold Colour

The first thing I want to explain to you in the gold karats FAQ guide is the different gold colours. The most common gold colours found at online jewelry stores & offine fine jewellery stores is yellow gold, followed by white gold and rose gold. There are other colours available but these are less common.

The colour of the gold doesn’t make a difference to the gold content (karat rating). This is because the alloy has the same amount of gold in it. The gold is mixed with different metals to achieve different colours.

Yellow gold can vary in colour. 18k yellow gold will have a brighter yellow colour compared to 9k gold.

Rose gold is achieved normally by mixing pure gold with other metals such as cooper into it.
White gold is made by mixing pure gold with metals such as silver and palladium. It is often coated with a metal named “rhodium”. The rhodium gives jewellery a really white appearance. White gold jewellery normally needs to re-rhodium coated every 12-18 months. Your local jewelry store and even some online jewelry stores can easily do this for a reasonable price.

When comparing metals of the same karat, white gold tends to be a little more expensive.

Gold Plated Jewellery (also known as GEP or GP)

Gold plated jewellery describes jewellery that has a layer of gold applied to a base metal by an electrolytic process. This gives a look similar to karat gold. The gold plating will wear off after time. Gold plated jewellery is a cheap alternative. This type of jewellery is widely available and can be found at online jewellery stores, online accessory stores and offline stores.

Gold Filled Jewellery (also known as Gold Overlay)

Gold filled jewellery is a solid layer of gold bonded with heat and pressure to a base metal such as brass. Gold filled jewellery is a great cost effective alternative to solid gold jewellery. Unlike gold plated jewellery, good quality gold filled jewellery wears as well as solid karat gold and has the same look and lustre. For more about solid gold jewelry, see gold karat FAQ guide part 1.

The layer of gold in gold filled jewellery must be 1/20th of the total weight of the product. This layer is 50 to 100,000 times thicker that gold plated jewellery.

Hardness

The difference in gold content also affects the gold’s hardness. 18k gold is slightly harder than 9k gold but this difference in hardness offers little practical advantage as they are virtually the same hardness. However, overall, 18k gold does tend to wear a little better over the years. Most online jewellery stores & regular fine jewellery stores would advise you to choose 18k gold for a wedding band as it wears a little better.

What does the term Karats refer to when describing Gold?

The first thing we need to cover in part 1 of Gold Karats FAQ guide is that the “K” in 9K or 10k gold stands for karats. Not to be confused with Carat (Ct), which is the unit of weight measurement for gemstones.

Karats is a measurement of the content of gold. Online Jewellery stores & regular jewelry stores rarely sell gold karats jewellery made from pure gold as gold is considered a soft metal and is too soft for everyday use.

Mixing the gold with other metals hardens it and makes it more durable and less likely to bend. The result is “karat gold”. Pure fine gold jewellery would also be too expensive for the average consumer.

Mixing gold also produces different coloured golds – see gold karats FAQ part 2 or go to our online jewellery store australia for more information regarding gold colours.

So “karat” is the content of gold used in a gold alloy in jewellery. i.e :

9k gold contains 37.5% pure gold (375 parts per thousand parts).
10k gold contains 41.7% pure gold (417 part per thousand parts)(include 10k)
14k gold contains 58.5% pure gold (585 parts per thousand parts).
18k gold contains 75% pure gold (750 parts per thousand parts).

The most common karat gold used in Australia is 9k and 18k. 18k is more expensive than 9k as it has a higher gold content. Both these types can be found at online fine jewellery stores and bricks and mortar fine jewellery stores. In the USA, 10k & 14k gold are most popular.

Gold Stamps (hallmarks)

The next thing to cover in this gold karats FAQ guide is the hallmark. Karat gold is normally stamped (hallmarked) to indicate the type. E.g. 9k gold would either be stamped 9k or 375, 18k gold would be stamped either 18k or 750. The stamp doesn’t indicate the colour of the gold, it only refers to the gold content.
Most countries have laws requiring gold alloys be stamped with one of the standard hallmarks. This said, a halkmark doesn’t mean the item is what is says it is.

Hallmarks should not be confused with a manufacturing stamp which is unique to the manufacturer.


What is Fine Gold?

You will see offline and online the terms fine gold jewellery, fine gold & fine jewelry. What do these terms mean? They normally refer to karat gold. In other words, fine gold jewellery is jewellery that is not gold plated.


What is Solid Gold?

You will see the term solid gold mentioned at online jewelry stores and at regular fine jewellery stores. Gold is normally named solid gold when it is karat gold or fine gold. For example 9k, 10k, 14k, 18k and 22k gold is often said to be solid gold. Jewellery is not considered solid gold if it is gold plated.


Understanding how to test gold and the different types of gold will help avoid paying too much for your next piece of fine karat gold jewelry at an online jewelry store or an offline fine jewelry store.

The first thing you should do is educate yourself about the differences between gold plated and gold filled jewellery. Then you will at least be able to ask the seller and understand what these terms mean.

The easiest way to test gold.

I would say that the most reliable and easiest way to test if you have real gold is to take it to a jewellery store. Some online jewellery stores may also offer this service.

Testing Gold Yourself:

Electronic Gold Tester These start at around US$100 and can be found by searching the internet for ‘gold tester’. To do this test you buy an electronic tester. It normally involves putting a clip onto the item and then placing the item in an acid. The tester then tells you what karat of gold it is.

This is a non-destructive test and can be accurate depending on the money spent on the tester.

Using a Testing Stone You can also buy these for around US$60. You rub the jewelry on the test stone leaving tiny fraction of the gold behind.

You then rub a gold test needle onto the stone near the gold sample. After this, you apply the appropriate acid as directed. If it is gold is will dissolve.

Acid Test this is reliable too. This allows you to distinguish if the piece is solid karat gold or just gold plated.

Using a very small file, file into the jewellery. Choose a spot which is inconspicuous. You then apply the appropriate acid. The gold will react to the acid. The kit will have instructions as to the reaction you are looking for.

Acids are very dangerous and the appropriate precautions should always be taken. This advice is of a general nature. Make sure you read the instructions thoroughly before attempting these tests. Most online jewelry stores won’t ship these kits overseas as the acids are dangerous chemicals.
