Daniel Craig and Rachel Weisz took the world by surprise last month, pulling off a James Bond-esque scheme, and marrying in a secret wedding ceremony. The pair had a quiet, intimate wedding ceremony attended by only a few special guests. Now, Rachel has debuted her Wedding Band while on the set of NBC’s the Today Show.

What do you think of their choice? Do you like the simplicity or would you have liked to see more opulence?
Justin Bieber is known throughout the world as the most popular teenage recording artist. However, he is not only a teenage heart throb, but has recently become a novice jewelry designer.

Justin has been seen sporting a necklace inspired by the TV show ‘Family Guy’ which he designed with the help of famous Beverly Hills jeweler, Jason Arasheben. The necklace which depicts the character ‘Stewie’, is worth over $25,000, contains 12 carats of precious stones, including red, yellow, and green rubies for his shoes and clothes and white diamonds for his head. The entire pendant is set in 14-karat yellow gold.
When people read or hear about gold, they immediately think yellow gold. Or these days white and rose gold. Most jewelers or manufacturers make rings using yellow, white, or rose gold. But did you know gold comes in other colors? You can find gold in green, purple, blue, brown, and black. These other types of gold are not as common for a few reasons, but some jewelry can be made using these types of gold.
Colored gold can be classified in 3 categories: 1.) the malleable alloys, which are white, yellow, green, and red (rose or pink) gold. 2.) intermetallic compounds which are the blue and purple gold and finally 3.) oxide layer of gold, generally black or brown gold. Before you buy that next ring or piece of jewelry, here is some information about the different types of gold, even the most common ones out there.
Yellow gold is the oldest and most common form of gold. Pure 24 karat gold is very soft and bendable. The color is yellow. When creating jewelry pieces, most jewelers use gold that is alloyed to strengthen the metal. The gold is usually alloyed with nickel and other alloys to harden the metal. But keep in mind, just because there is less karat in the gold to make it harder, does not mean the ring or jewelry piece will last longer. For example, many people believe 10 karat jewelry would be the best piece of gold jewelry to buy because there is not as much gold parts and it is a lot harder. However, the jewelry piece does not last as long as say 14 karat or 18 karat. The more pure gold in the jewelry or ring, the longer it lasts; even if it is softer. The ring or jewelry will wear much better over time. A rule to keep in mind: it is better to buy jewelry, especially wedding rings or bridal jewelry, between 14 karat and 22 karat. Your jewelry will wear a lot better than 10 kt jewelry.
Another common gold is white gold or rose gold. White gold generally comes in 14kt or 18kt. White gold is usually alloyed with manganese, palladium or nickel. Each of the alloys are used for different purposes. If gold is alloyed with nickel, then the white gold is generally hard and strong. If gold is alloyed with palladium, then the white gold is generally soft and pliable. Each alloy used has a different purpose in jewelry. One thing to remember is white gold does not naturally have the white color. Its true color is a pale yellow, dull gray or tint of brown. Because the natural color of white gold does not look like platinum or palladium, the jewelry industry usually rhodium plates white gold to give it the platinum, silver, or palladium color. Rhodium plating is a process that layers the gold with a white metal. This does not harm or hurt the quality of the piece of jewelry. The rhodium plating does wear off over time but it can be plated as many times as you need. And for some people the rhodium can last a long time and for others it does not last as long. The wear of the ring will vary from person to person. One thing to keep in mind is rhodium plated jewelry should not interact with chlorinated water. This will wear the plating quickly.
The other common gold is rose gold. In the early 19th century, rose gold (or pink gold) used to be called Russian gold because it was very popular in Russia. The highest karat for rose gold is 22 karat which is also known as crown gold. To get the rose color, gold is alloyed with cooper. This type of gold has different shades from light pink to deep red, depending on the amount of cooper alloyed with the gold. And when you combine white or yellow gold with rose gold, you can create beautiful pieces of jewelry. The rose gold adds some accents to the ring.
Green gold is another colored gold that is listed under the category of malleable alloy along with yellow, white, and rose gold. Green gold is gold created by leaving the cooper out of the mix of alloys. Generally, green gold is made using gold and silver together. Before 850 B.C., the Lydians use to call green gold, electrum. These days you won’t find as much jewelry with green gold; unless, the craftsperson uses it to accent parts of the jewelry piece. Using green gold is just like using yellow, rose, or white gold in jewelry. The characteristics are the same.
Now, that you know the 3 most common types of gold and about green gold, let me explain the other interesting colors of gold. These ones are generally categorized as intermetallic or oxidized layer of gold.
Purple and blue gold are listed as intermetallic. Purple gold is also called amethyst or violet gold. The gold is alloyed with aluminum rich. Purple gold is more brittle and generally used as a layer and not in a solid piece of jewelry. It is used more to provide subtle design to the jewelry piece. Along with purple gold, blue gold is also used for subtle design purposes because it has a poor resistance to corrosion. Blue gold is alloyed with indium. Depending on the alloys, blue gold can be as light as a slight blue color to a deep rich royal blue color. Also, blue gold can be created through oxidation, which is a form of changing the surface of the material being used. These are two types of colored gold that are great for designing or adding accent to the jewelry piece, but not always the best option for jewelry pieces bought to last a lifetime.
And finally, I bring you to the last of the colored gold. Black gold or brown gold! This type of colored gold is formed using various methods:
1.) It can be made by electroplating the piece of jewelry. This refers to using a black rhodium or ruthenium to plate the gold used. It is very similar to the process of rhodium plating white gold. Overtime the black rhodium will fade and the true color will reveal, which is generally white gold or yellow gold. This process can be redone, just like rhodium plating.
2.) Patination, which adds sulfur and oxygen to the compound and changes the gold to black.
3.) Chemical vapor deposition, which is a process to produce thin films of black gold on the jewelry. Generally, the chemical vapor deposition is used with amorphous carbon (an activated carbon).
4.) Controlled oxidation, which is a process to oxidize the gold using chromium or cobalt. Black gold has a combination of 75% gold and 25% cobalt.
5.) Laser technique, which is a process to absorb all the lights to create a deep black color.
Creating black gold is formed by these different methods. Looking at WeddingBands.com and their new line Royal Duet, they show a use of black gold or black rhodium. They do not state how they create the black color on their wedding rings, but one thing is for sure, they have a beautiful line using the black color in their rings.
In the end, when you are looking to buy jewelry or a ring, remember how they are made. This will be very helpful when purchasing your next big item in jewelry. I hope I have taught you some useful information. Until next time, please remember learn about the jewelry your buying, it will make the whole experience better!
