hallmark

One of the main uses for Gold is Gold Jewelry. When buying a gold necklace, a pair of earrings, a bracelet or ring you really need to look at the Gold content in what your buying and think about what this jewelry will be used for. Many people are not aware that the Gold content or the pureness of the gold alters the softness or hardness of the metal. Gold is measured in caratage or ‘kt’. You will need to determine how often you will be wearing your jewelry. Gold is a soft metal and can easily bend or be broken when in its most pure form.

When buying gold jewelry you may Purchase 24kt, 18kt, 14kt or 10kt Gold in the USA. Other countries also allow 9 & 7 kt Gold to be sold. The Purest of gold is 24 kt. when you add other metal alloys such as copper, silver or palladium the hardness of the gold is increased. So the 24kt gold will be softest and then 10kt the strongest due to the other metal added to the gold. 24K is pure gold

Purity of Gold

Originally, the gold marks were impressed by a union of goldsmiths. These goldsmiths are the individuals who examine or check the purity of the gold product, and they are the people that mark the gold in their guild hall. By this process, the name “hallmark” was originated. Nowadays, these hallmarks are managed by assay offices. From this assay office gold products are examined for their purity through several tests.

There are two main methods for testing the purity of Gold. They are the Touchstone Gold test and the other is using XRAY Fluorescences. .

Touchstone Method

This method involves scratching some of the gold along a touch stone and the using different strength acids to determine the purity.

  1. Strike the unknown Gold down the touchstone to leave a thin layer of Gold on the stone.
  2. using standard testing needles trike a line for 10, 14, 18 and 22kt Gold
  3. Use the acid that has the strength to dissolve the 14kt Gold and wipe it across the Gold lines.
  4. If the unknown Gold is stronger than the acid it will not dissolve.
  5. Continue using stronger acid solutions until the Gold is dissolved.

XRAY Fluorescence

This technique is the fastest way in identifying the fineness of such gold item. It is also useful with accuracy between 2 to 5 portions per parts. This not only evaluates the transparency of gold it could also verify the amount of the added impurities.

Destructive Test

For an accurate extent of the pureness of the gold parts for every item, a destructive method is needed. The most accepted method used in identifying the pureness of gold is called “Cupellation”, or “Fire assay”. This approach requires the dissolving of the golden item. The metals utilized in the gold alloy is divided and measured. This technique is the considered as a perfect one.

Since Fire Assay is not a helpful method and all gold products produced, it must be evaluated. The standard practice includes all three evaluating methods to be employed. While choosing a small number of items to undergo such process like cupellation, the other will undertake the touchstone technique either or the x-ray fluorescence system, or sometimes both.

gold jewelryWith these techniques used in identifying the excellence or transparency of gold in alloys, then you can be guaranteed on what you seize or own meets up the claim of the producers of that item. However, Gold hallmarks indicate that your gold piece qualifies the international standards for gold distinction. It also indicates the excellence of your golden item in such a way.

Additionally, manufacturers certified that their claim for the transparency of gold employed for each item is certainly true. Pure gold is usually too elastic to be used for anything. For any reason, other metals are combined to gold and produce gold alloys to be employed as unrefined material for creating gold crafts. The dilemma with this is that if the metal added to gold, then cash value of gold will go down.

The Durability of the Gold

What are the various marks of gold? Most of the time, gold can be marked in several ways. Gold jewelry is often pounded with specific marks that offer information on its fineness. These marks assist the consumer to find out the value and genuineness of every piece of jewelry. Most jewelry has at least one mark specifying the content of the gold. Therefore, all consumers who want to purchase jewelry should better check the marks.

18Karat Gold

The term “karat” implies the amount of gold in a particular item. Gold jewelry can vary from 24 Karat to 10 Karat Gold. In fact, 24 Karat Gold is considered 100 % pure gold, while 10 Karat is 41.6% pure gold. A piece of jewelry marked 18 Karat means that it is 75% fine gold.

In fact, 24 Karat Gold is 100%; it is essentially not the most attractive mark in jewelry, because pure gold is too elastic. In order to increase the toughness and hardness of such gold, it needs to be combined with other precious metals like nickel, copper, zinc, palladium, and silver.

Moreover, Gold is the most impressionable and long-lasting among all metals. It does not discolor. Pure Gold is almost protected from the effects of oxygen, air, and water. Each country has a diverse series of the system especially in hallmarking gold. In U.S., the transparency of gold is specified by karat.

Pure gold has 24 Karat, but it is rarely used to create jewelry because pure gold will not seize gemstones and twists too easily. Metals such as nickel, zinc, copper, and silver are used with gold just to enhance its potency and permanence. Metal preservatives will also verify the karat and color of the gold.

However, it is not suitable to calculate the transparency of the gold employed in jewelry. Traditional or classic jewelry exclusively based on a gold hallmark. Several pieces of jewelry were never hallmarked, and some of them have been damaged with wear and use. Most of the time, gold marks were wrong.
