So you want to buy a diamond, but you’re not sure where to start. Buying a diamond can be one of the biggest investments you’ll make in something that you have the least amount of knowledge in.

Everyone has heard of the four C’s when it comes to buying diamonds: Cut, Clarity, Color and Carat. We’ll go over each of these terms so you can both impress your friends and have confidence you have the information when you need to buy a diamond you’ll love.
Guide to Diamond Cuts
The first thing anyone notices about a diamond is its shape. Is it round? Is it an oval? Is it a heart shape? But the C, for Cut, actually refers to how well those shapes are cut.
The cut of a diamond, no matter what the final shape, is the most important step in the life of a diamond. A skilled diamond cutter can make or literally break a diamond. Better clarity is advised, for different shapes, for example. The cut is probably the most important of the four Cs because it will determine the overall beauty of your diamond, no matter what final shape you pick. And when it comes to a diamond, it’s all about the sparkle. From an uncut diamond to a final gem, the diamond can loose as much as 60 percent or more of its size. It can take a 3 carat uncut or raw diamond to produce a 1 carat finished gem.
The Gemological Institute of America (GIA) grading scale rates cuts as ‘Excellent’, ‘Very Good”, ‘Fair’, or ‘Poor’. The American Gem Society (AGS) rates cuts on a scale of 1 to 10.
In any diamond cut, there are three main cuts; there is the table, or the top of a diamond, the girdle, the middle of the diamond, and the pavilion, the bottom. An excellent cut will allow light to enter a diamond, bounce around its facets like reflecting mirrors and exit the top in an exciting display of either white light, referred to as brilliance, or a rainbow of colors, called fire. A diamond with an excellent cut will catch your eye and can even look bigger than its actual carat size. Those are the rings and the diamonds you’ll find yourself distracted by when you find yourself staring at a ring. Different cuts and shapes produce different amounts of fire and brilliance.
For some of the diamonds sold by Ben Bridge in our Forevermark collection, only two master diamond cutters, called Diamantaires have met the standards required to cut our Signature Forevermark diamonds.
The cut obviously determines the shape of a diamond and there are shapes that, when cut well, offer the most brilliance and fire. There are also shapes that show off an elegant diamond with amazing clarity. There are shapes that can look larger for their carat size. The most important thing when it comes to a diamond, however, is the shape you connect with, because if it’s not the look you want, it doesn’t matter if it’s an excellent cut.
A one carat round diamond with the perfect proportions, the perfect pavilion depth and the perfect angle, won’t be the perfect diamond if you’re dreaming of a princess cut. The diamond is important, but the look on their face is what really matters.
Fall in love with your diamond, because it should be with you a long time. According to experts, diamonds can be as old as 3.5 billion years old to a mere 900 million years young. And although you probably won’t have yours that long, make sure it’s one you love.
What to look for in different cuts and shapes and what they mean.
This cut tends to be the most balanced, versatile and popular cut for gemstones because it allows the stone to be faceted to enhance the sparkle and play of light. Round cut diamonds will give you the most sparkle of any of the diamond shapes, although any gemstone can be cut into a round stone. If this is your favorite cut, you might be more of a traditionalist and you definitely know a good thing when you see it.
On a classic round brilliant-cut diamond, the fifty-eight facets must be precisely aligned and proportioned for maximum brilliance. If a round diamond is cut too deep or too shallow, light escapes out of the bottom or the sides instead of reflecting back to you, which explain why some diamonds are more brilliant than others.
Ben Bridge also offers a Signature Forevermark diamond with an additional 8 facets. This cut and shape has been described as the most beautiful ever offered. The Signature Forevermark is only offered through Ben Bridge and only about one percent of stones qualify for this classification because the qualifications are so rigorous. Other jewelers may have signature diamonds, but they are not the same as those offered through Ben Bridge Jewelers.

Guide to Diamond Clarity
When you’re talking about the clarity of a diamond, you’re actually referring to the lack of something. The fewer tiny particles, or inclusions, trapped inside of a diamond the better and the fewer blemishes on the outside the better the clarity of a diamond.
Clarity matters in some cuts more than others. In an Emerald cut diamond, for example, you want a diamond with an extremely high clarity, because the cut and shape involved will highlight any inclusions. Inclusions can be less noticeable in a round cut if they’re off to the side
Diamond clarity is measured from flawless to I3 on the GIA clarity scale, depending how many flaws are visible under a jewelers loop, or microscope. At flawless, no inclusions or blemishes are visible to a skilled grader even at 10X multiplication. These diamonds are very rare and because of that, can be very expensive. At the opposite end of the scale is an I3 grading, where the flaws are visible under 10x magnification, and could affect the shine and sparkle of a diamond.
The GIA clarity scale was created to clarify (no pun intended) the grading of diamonds. Before the scale, jewelers used different phrases and the buyer might not always get the same grading for their diamond from different jewelers.
The GIA has 11 grades for clarity ranging from Flawless to Included. While the higher clarity grades are more valuable, many people consider that inclusions add character to the diamond. They can be thought of like your diamonds’ fingerprint; they make your diamond unique.

Guide to Color in Diamonds
After the shape of a diamond, color is probably what you notice the most. The GIA color scale grades diamonds on a scale from D-Z starting at D, which means no color, and ending at Z which means a lightly colored diamond, usually yellowish or brownish. Are there any diamonds that have a color grade of A-C? The short answer is no, because when the GIA developed the color grading scale used by most of the world today, they started it at D.
Before the GIA color scale was developed in the 1950s, there were systems that started at A, and one that used number 0, 1, 2 etc., and even a color system that used Roman numerals. Like the clarity scale the GIA wanted to differentiate its system and start fresh. The GIA color grading scale gives buyer’s confidence that a diamond with a color grade of H I or J is the same in Japan and New York and Seattle.
Diamonds that are color grade D are very rare. Diamonds graded up to J on the GIA scale are considered near colorless. It becomes easier for the consumer to see color past the M, but a color grade that’s higher on the scale can be a way to save money on your diamond. Some people prefer a diamond with a higher color grade because they think it looks warmer. A warm candle-light color can invoke romance.
Diamonds are usually color graded before they’re in a setting because a setting of rose gold, yellow gold or white gold can make a diamond look different colors.

Guide to Fancy Colored diamonds
When you go beyond the color scale at Z, you have diamonds that are considered Fancy colored diamonds actually come in every imaginable color from red, the most rare, to blue, the second most rare, to yellows and browns, the most common color. Unlike what people think of as traditional diamonds, where the less color the better, in fancy diamonds, the more color the more valuable the fancy diamond.
Fancy diamonds are graded from faint to fancy, to vivid.
While you get to yellowish diamonds at the top end of the color scale, the truly yellow diamonds are beyond the scale. Beautiful yellow diamonds live in the world of fancy diamonds. Vibrant Canary yellow, Sunlight yellow, the reason they’re yellow is because of a tiny bit of nitrogen that was in the mix of carbon when the diamond was formed, but nitrogen aside, they just look stunning. Yellow diamonds are one most common fancy colored diamonds.
Although they’re found around the globe, most pink diamonds come from Australia today. Where their color comes from is still under debate by scientists trying to discover what makes a pink diamond pink. One theory is natural radiation they were exposed to while they lay underground for the millions of years it took them to work their way to the surface. Another theory is that they were experienced some sort of molecular shift when they were first formed because of a seismic shift. Whatever the cause, pink diamonds are beautiful and can be incredibly romantic. They also hold the record for the most expensive colored diamond sold at auction.
Black diamonds became popular in the 1980s, and have soared in popularity ever since because of the drama they bring and because they are affordable. The color comes from tiny bits of carbon or other inclusions trapped in the diamond as it formed. Almost all black diamonds are treated in order to produce an even color.
Brown diamonds are the most common color variety of natural diamonds. They came into popularity when a large mine in Australia began marketing brown diamonds as chocolate diamonds and while the chocolate marketing didn’t last, the diamonds did. Today they’re often set with other diamonds to enhance their color and offer a striking look. Brown diamonds edge out yellow fancy diamonds as the most common color.
The most famous blue diamond, and probably the most famous diamond in general, is the Hope diamond. At just over 45 carats, it’s not the largest diamond, but the value of the Hope diamond is an indication of how rare blue diamonds are. Most blue diamond’s sold today have been treated. There was even a diamond reported by the GIA of a natural diamond that had a blue lab-grown diamond top layer, like the icing on a cake.
Guide to Diamond Carats
It’s probably the most common question when it comes to diamonds, how many carats is your diamond? Is that a one carat ring? But the carat also one of the most misunderstood aspects of diamonds. Carats actually refer to the weight of a diamond, not the size, but obviously the heavier the diamond, the larger it is. While today a one carat diamond weighs about 200 mg, carats originally it referring to an actual carob seed.
Larger diamonds are rarer than smaller ones, and as the carat weight increases, the value of the diamond rises quickly. The increase is not directly proportionate to the size, so a one-carat diamond will cost more than double that of a 1/2-carat diamond (assuming color, clarity, and cut are identical). Weight does not always enhance the value of a diamond, either. Two diamonds of equal weight may be unequal in value, because so many other factors affect the cost of a diamond, such as cut, color, and clarity.

Ikuma, the Canadian Diamond
Ikuma is the native Inuit word for fire which seemed an appropriate name for a diamond collection. There are three mines in far Northern Canada where these are mined. When these mines were first opened they worked with the indigenous communities to make sure they meet the rigorous environmental and social regulations for the region. These are the ultimate in a conflict free diamond; they moved more than 5,000 fish when the mining threatened the lake they were living in.
