What Are Dirty Diamonds?

Published by under Diamonds

A dirty diamond is one of two things: a rough diamond, or a diamond that hasn’t been cleaned in a while. Rough diamonds are uncut and unpolished - hence, they are dirty. But that type of dirty diamond will soon be cut and polished and sitting in a beautiful jewel box in a display case. Then someone will purchase it, and before long, it will become a dirty diamond once again.

Diamonds become dirty. When you wash your hands with a diamond ring on, soap scum clings to it. When you put on hand
lotion, it gets grease on it. Shower with your diamond earrings or necklace, and again, you get soap scum. In one short day, your brand new diamond could be dirty!

Purchase an ultrasonic jewelry cleaner the same day that you purchase your diamond jewelry, and use it every single day, without fail. The clarity of the diamond changes when the diamond is dirty - it loses its sparkle. By taking one minute each day to clean your diamond jewelry, you can avoid this, and your diamonds will never be dirty!

How Diamonds Are Mined

Published by under Diamonds

We seldom think about how the diamonds we wear came to us. Natural diamonds, as opposed to synthetic diamonds or fake diamonds, are mined from the earth. There are currently two methods of mining diamonds: Pipe Mining and Alluvial Mining.

When pipe mining is used, the diamonds are extracted from the earth through volcanic pipes. These are not man-made pipes. These are natural pipes in the ground. Shanks are put into the ground next to the pipes, and tunnels are driven into the deepest parts of the pipe. The diamonds are not sorted out at the mine. Instead, huge rocks that are full of diamonds are brought out of the mine and moved to a screening plant for separation.

The Alluvial mining method is done in riverbeds and on beaches. Walls are built to hold back the water and the sand on the bank or beach is moved with a bulldozer until the level of earth that diamonds can be found in is reached. Again, the diamonds are not sorted here. Instead, the sand that contains the diamonds is bulldozed into trucks, and taken to screening plants.

How to Sell A Diamond

Published by under Diamonds

There are many reasons why you may want to sell a diamond that you own. Perhaps you’ve gotten divorced, or you are strapped for cash. The reasons why don’t really matter - getting the best possible price is what counts! The way to obtain the best price for the diamond is to not be in a rush. Slow down, and carefully consider all of your options - there are many.

First, have the diamond appraised. In fact, have it appraised by two or three jewelers to get an accurate idea of the diamonds value. Tell the appraiser that you want the Rapaport Value. This is the wholesale value of the diamond, and it basically tells you the highest price that you can sell your diamond for. If your diamond has no certificate, you should
consider getting a certificate from GIA. This may help you get a better price for the diamond as well.

How Diamonds Are Cut

Published by under Diamonds

In their most natural form, diamonds are - “well” quite ugly. They have no luster or shine, and in fact, look like nothing more than broken glass. A diamond must be cut, and then polished before it actually becomes a thing of beauty.

Diamonds are cut with saws, into round shapes. From the rounded shape, other shapes may be cut, such as heart shapes
- but the shape is less important than the quality of the cutting that is being done. If the diamond is poorly cut, it will lose light, and it will not sparkle and shine very well. Each facet of the diamond must be carefully cut into the geometrical shapes that allow the diamond to sparkle and shine, then the entire diamond is cut into a specific shape, such as an emerald cut or a princess cut diamond.

Once the cut is done, the diamond is put into a dop, which resembles a cup with another diamond - only a diamond is strong enough to smooth the edges of another diamond. Once the diamond has been cut and shaped, and had the edges smoothed in the dop, it is polished on a scaif or a diamond polishing wheel.

How to Buy Diamond Engagement Rings

Published by under Diamonds, Wedding

There is much to consider when purchasing a diamond, especially diamond engagement rings! The tradition of presenting a woman with a diamond engagement ring when proposing began in 1477 when Archduke Maximilian presented a diamond ring to Mary of Burgundy and in most cases, the woman you plan to propose to will expect a ring to accompany that proposal!

First, determine how much ring you can afford. Most people use the “two months salary” rule. This means that the ring should cost the equivalent of two months of your current salary. Because you have other bills to pay, saving up this amount of money may take quite a bit of time. You should consider financing. Simply go to the jeweler of your choice and tell them that you plan to buy an engagement ring, and that financing will be necessary. Go ahead and get the credit check out of the way, find out what your payments will be, and how much of a down payment is required.

Choosing The Cut of A Diamond

Published by under Diamonds

There are many different cuts of diamonds to choose from. The cut essentially refers to the shape that the diamond is cut into -unless you are in the diamond or jewelry business, but this shape has a great impact on the much the diamond sparkles.

The most popular cuts are heart, marquise, oval, pear, princess, round, trillion, and emerald cuts. The shape has an impact on how much the diamond sparkles, but the actual cutting itself - when the diamond cutter actually cuts the diamond into a
particular shape also matters a great deal. If the diamond is poorly cut, it will lose its sparkle.

Synthetic Diamonds

Published by under Diamonds

The first synthetic diamonds were produced by General Electric in 1954. A synthetic diamond is basically a rock that has the durability, refractive index and hardness of a natural diamond but it is made by man. A synthetic diamond should not be confused with stimulant diamonds, such as glass, cubic zirconia, or moissanite.

Although the technology for synthetic diamonds came into play in 1954, no synthetic diamonds were ever seen on the market until the 1990’s. This was due to the fact that it took many years for General Electric to produce a synthetic diamond that could compare with the quality of a natural diamond and when they figured out how to do it, they found that it cost more to produce a synthetic diamond than it did to mine and cut natural diamonds.

Finally, a small company by the name of Gemesis Corporation figured out a way to produce synthetic diamonds that were of the same quality as natural diamonds, at a cheaper price. Today, Gemesis produces synthetic white diamonds, and colored diamonds as well. These diamonds sell for about 1/3 of the cost of a natural diamond, but there is a shortage of them, and they are hard to find. In fact, it seems that synthetic diamonds are rarer than natural diamonds!

About Diamond Weights

Published by under Diamonds

Diamonds are measured in Carat Weight. One carat weighs 200 milligrams. If a diamond is referred to as four grains, this also means that it is a one carat diamond. The word Carat comes from the word carob. A carob is a bean that grows on a tree in the Mediterranean. In times past, if a diamond weighed the same as a carob bean, it was one carob, or one carat.However, in the far east, where Carob trees do not grow, rice was used to measure the weight of a diamond. If a diamond weighed as much as four grains of rice, it was four grains or one carat as we know it to be now. The majority of diamond purchases are for diamonds that are 1/3 of a carat.

Beware when shopping for diamonds that are already set or mounted. If more than one diamond is used in the piece, the tag on the jewelry will give the CTW or Carat Total Weight - it does not tell you the carat weight of each stone in the piece. You need to ask the jeweler for the total carat weight of the largest diamond in the piece to truly understand what you are buying.

Diamond Certificates

Published by under Diamonds

A diamond certificate is also known as a Diamond Grading Report. This report comes from the Gemological Institute of America (GIA), and you should require this report when you are purchasing a diamond.

With a diamond certificate, you can verify the color, cut, carat, weight, and clarity of the diamond. You don’t have to worry about a diamond dealer telling you anything less than the truth, because the certificate comes from the GIA and not the dealer. You may be required to pay for the certificate, but the cost is usually low, and in many cases, it will help you negotiate a better price on the diamond or keep you from purchasing a lower quality diamond altogether.

How to Spot A Fake Diamond

Published by under Diamonds

In this world of advanced technology it is almost impossible to simply look at a diamond and determine whether it is real or not - especially if you don’t know much about diamonds. There are some steps that you can take to avoid buying a fake diamond, however.
