What Are Dirty 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!

Selecting Diamonds

Diamonds are graded for certification by laboratories using grading criteria. Four of these criteria are critical to understand when making a diamond purchase or investment. Known as the "Four C's" these criteria are: color, cut, clarity and carat.

Color is the result of the composition of a diamond and it does not change. When a jeweler is describing the color of a diamond they are referring to the presence or absence of color in white diamonds. Because a diamond with no color allows maximum light to pass through, colorless diamonds are preferred for their sparkle.

Cut refers to a diamonds reflective quality. Most diamonds are cut with 58 facets. The brilliance of diamonds is heavily dependent on the cut. The different angles and the finish of a diamond determine its ability to reflect light and cause its brilliance and fire. Remember that the cut of a diamond can have an impact on its durability as well as its beauty. Some cutting faults can make a diamond prone to breakage. A diamond that is cut too thin can also cause light to leak out of the back and the diamond will lose some of the sparkle and appear not to shine. So, as you can see the Cut is probably the most important of the Four C's.

During the formation process, inner flaws, or inclusions occur in most diamonds. The number and size of these inclusions determine what is referred to as the clarity of a diamond. Diamonds that are clear create more brilliance and therefore are rarer and highly priced. To be considered "flawless", a diamond must have no surface or internal imperfections visible upon being viewed by a skilled diamond grader using 10 power magnifications.

Carat is the unit of weight by which diamonds are measured. One carat is equal to 200 milligrams. A carat is divided into 100 segments called points. 150 points would equal one and a half carats.

When you go to the store to make that all important diamond purchase, do not be shy! Ask questions, get the answers needed to make an informed purchase. Shopping for certified diamonds enables you to make an informed selection. Knowing the "four C's" allows you to comparison shop and purchase the best diamond at a fair price. But, before making a purchase, shop around and decide what shapes and styles really appeal to you. Enjoy your diamond for years to come!

How to Spot A Fake Diamond

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.

First, only deal with reputable jewelers, and when you find a reputable jeweler, stick with them. Avoid buying diamonds or other jewelry from jewelers that you have never dealt with before in the past. Ask to see the certificate for the stone. If no certificate exists, walk away.

Look at the setting that the stone is in. Fake diamonds, such as zirconias, are usually set in low quality metals. Take a close look at the stone. Fake diamonds are not durable - natural diamonds, on the other hand, are the most durable stone on the planet. Look for scratches or nicks.

After purchasing a diamond, take it to another jeweler for appraisal. In fact, take it to two or three other jewelers for an appraisal to make sure that the appraisals are all fairly close. If you find that you have purchased a fake diamond, you may be accused of making a switch when you return to the store of your purchase; therefore, it is important to have a certificate for the diamond. No two stones are alike.

How to Clean your Diamonds

Through our day to day movements our diamonds get smudged and soiled. Even when we are not wearing them, they collect dust. Lotions, soaps, our natural skin oils, can cause film and grime on diamonds and inhibit their brilliance.

Want to keep that Brilliance and Shine? Diamonds require cleaning so that maximum amounts of light can refract fiery brilliance. Remember that all it takes is a few minutes and a little care to keep that diamond as fiery as the day you first saw it.

You can use an small soft brush such as an eyebrow or lip stick brush and soap and water to clean your jewelry. Simply make a bowl of warm sudsy water with a mild detergent and place your pieces in the mixture. Then brush the diamonds with the soft bristles of the brush while they are in the suds. You will need to make certain that you rinse them clear of the suds after cleaning them. You can use a small kitchen strainer such as a tea strainer to contain them while rinsing under warm water. Use a lint free cloth, or a jewelry polish cloth to pat them dry.

If your diamonds are in need of a stronger cleansing, you may want to soak them for 30 minutes in a solution of half and half water and ammonia. Once they have soaked for 30 minutes, remove them and gently brush the mountings with a small brush. Then replace the pieces to the solution and swish them around in the mixture before removing them to rinse and pat dry.

If you find your self too busy to be mixing soaps and ammonias, many department stores sell liquid jewelry cleaners. Most are kits, with everything you need included. You need to read the labels to determine the one that is right for your diamonds and other jewelry. Read the complete directions and follow all the precautions.

And if you find yourself more the "high-tech type", even in your diamond cleaning routine, there are multiple ultrasonic cleansers on the market. These machines use high-frequency to create a cleaning motion. All machines are not the same, so please read the instructions before using.

Only you can choose the cleaning method right for you. But, it is essential to keep your jewelry clean to keep it brilliant and sparkling. Between cleaning, try not to touch your clean diamonds with your fingers or handle your jewelry by its edges. This will help maintain its shine and brilliance for longer periods.

How to Buy Diamond Engagement Rings

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.

Now, have your mother, sister, or your girlfriends best friend take your girlfriend shopping, and make sure that they gaze at the engagement rings to get an idea of what she might like. Make sure that the jewelry store you buy the ring from will allow you to return the ring, if that is required, or allow your girlfriend to exchange it for another if she isn't happy with it!

How Diamonds Are Mined

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.

Diamond Grading Reports

You've been told that having a certificate or a diamond grading report is important, and as a responsible consumer, you get one - unfortunately, you probably won't understand a word of what is on that diamond grading report, unless you are a jeweler.

On the color grading scale, D, E, and F mean that the diamond has no color. G, H, and I means that it has very little color. J, K, and L means that the diamond has a slight yellow color. P, Q, R, S, T, U, V, W, and X means that the diamond is a darker shade of yellow. Z means that the diamond has a fancy color - other than white or yellow. On the color grading scale, D is the most valuable, and X is the least valuable - however diamonds that get a Z rating are the rarest and most expensive diamonds in the world.

There are many aspects to a grading report. Figuring it all out can be very confusing. You should talk to a jeweler you trust, and have them explain everything on the diamond grading report to you.
