Information about gold!

Jewerly
 

Colour
For the jewellery market, two types of gold are utilised by designers. These are white and yellow gold. Yellow gold is perhaps the most commonly known type of gold. For purchasing jewellery, the colour of gold should be considered, especially in regards to the wearer’s skin tone and colour.

Carats
Gold is measured in carats. This standard denotes the amount of pure gold in the mixture. Twenty four carat gold is the highest purity of gold. This means that the piece is pure gold. Other rankings are 22 carat, 18, 14 and 9 carat gold. These denote that anything from 22 to 9 parts out of 24 is gold. The rest of the alloy is made up of other metals. In some parts of the world, instead of carats, gold is measured in fineness. Fineness is denoted by a three digit number. In the fineness rankings, 22 carat gold is measured by the number 916, while 9 carat gold is 375.

Why is gold so popular?
Gold is the most sought after metal for jewellery for two main reasons. First and foremost is the value which our society has placed on gold. This value has been inherited from previous civilization upon which ours was built. Secondly, gold has a lower melting point than almost any other precious metal. Due to this fact, gold jewellery is far easier for a designer to work with and repair.

Gold is not hard as diamonds
The flip side of this is that pieces of gold jewellery that have precious stones in them are more prone to damage and breakage depending upon the setting and wear. However, this should not deter anyone from purchasing and wearing gold jewellery. The best practice is to be careful with gold
jewellery, especially with precious stones mounted on or in it, and buy a higher carat of jewellery for a safer setting. Removing jewellery during sleeping, bathing, swimming and sports is also good practice. The only other piece to consider is the jeweller from whom you are purchasing the piece. Look for reputable places that have a history of good business.

Gold Jewelry
Perhaps no other substance on earth has captured the hearts and minds of man more than gold. Popular for its rarity and luster, gold quickly became a method of payment and a key component used in the manufacture of jewelry when it became fashionable during the times of Alexander the Great. After a temporary decrease in status, gold regained its popularity as a jewelry staple often seen used in
gold rings.
during the 15th century and continues to be popular today. Gold is the most easily worked of all metals and ranges in softness based on its purity. Generally pure gold is too soft for use in jewelry, so it's commonly mixed with alloy metals such as copper and zinc. Below is a breakdown of the percentage of pure gold in each of the popular karat weights:
24 Karat: 99.9% Pure

22 Karat: 91.7% Pure

18 Karat: 75% Pure

14 Karat: 58.3% Pure

12 Karat: 50% Pure

10 Karat: 41.7% Pure

When selecting jewelry like

gold necklaces
or bracelets, it's important to balance gold purity with the durability. Jewelry items like rings and bracelets often take more abuse and are much likely to become deformed if softer gold is used; as a result, 18 Kt or 14 Kt Gold may be a better selection for those types of items. In addition, there are a number of other forms of gold that must be considered when shopping for jewelry. They include:

Gold Vermeil Jewelry
uses sterling silver which has been gold plated. The highest quality Gold Vermeil is 24K, but it can be made with varying qualities.

Gold-Filled Jewelry
employs a process in which gold is bonded to a base metal alloy such as nickel or brass. Commonly, the amount of gold used must make up at least 5% of the total weight and all exterior portions are solid gold. Most gold-filled jewelry pieces tend to be 18Kt.

Gold Plated Jewelry
employs a base metal which is then electroplated with gold. Usually a steel or brass item dipped into a bath of electroplating solution that deposits a thin layer of gold on the jewelry. The gold layer is less than gold filled, quite thin and will wear off faster than gold-filled, Further more some jewerlest take it upon them selves to dip the item at hand for a prelonged amount of time to give the item a thicker layer wich make the gold last longer and harder to fade away. And some dip the item more than once, and that will cause a darker yellow color of the gold.

*Note: How to take care of your gold plated jewelry?

 Make sure you put your jewelry on AFTER all aprays/perfumes. If you are wearing a ring/bracelet make sure you take them off to wash your hands and put on lotion(make sure it is fully absorbed before puting jewelry back on). Unfortunately, sweat will tarnish the jewellery eventually. Clean your jewelry with warm, soapy water. Never use jewelry cleaners on plated jewelry - it will tarnish faster.
