A diamond's cut determines how effectively it returns light to the viewer's eye: a well-cut round diamond appears brilliant and fiery, while poorly cut stones look dark and lifeless. Well-cut diamonds often appear larger than stones of the same carat weight.

Please be aware with diamonds when we refer to cut we are talking about the quality of the cut by the diamantaire. When we talk about shape we are referring to whether the diamond is round, oval, cushion, marquise or any other special shape.

Brilliant round diamonds represent over 70% of diamonds sold across the world. The Princess cut is the second most popular, and in recent years we have seen the Cushion cuts becoming more popular. But all diamonds are really beautiful so it's very much a personal choice as to what you want.

A Gemological Institute of America (GIA) diamond certificate assures the value and quality of your diamond. GIA is the gold standard in diamond grading. GIA Reports detail key characteristics of each diamond. Diamonds4Crypto only uses the GIA to certify our diamonds.

We ship every loose diamond with an independent GIA report. This report can be examined by a qualified gemologist and compared against the unique characteristics of your diamond.

It is important to understand the 4Cs when buying your diamond. Please look at the GIA grading report which is available on every diamond we sell. For reference, Carat is the weight of the diamond; Clarity refers to the inclusions and other marks found in a diamond; Color is either a reading of how white the diamond is with D Color being the whitest, or refers to non-white colors from yellow to brown to other unique fancy colors such as red, pink, blue, or green.

The GIA are the 'gold' standard in grading and,as such,we believe buying a diamond with a GIA Report/Certificate provides our customers with the confidence they need to buy on-line.

Shaped like the fruit, the Pear shape combines the Round Brilliant and the Marquise cuts to form a tapered teardrop. This unique shape is often referred to as representing 'tears of joy'.

Whichever way you wish - however, the most common way of wearing it is with the tip of the pear pointing towards your fingernails. But it is your choice completely...there are no rules here.

Round brilliant cuts have the most sparkle,but Cushion cut diamonds are still brilliant and due to their larger facets they also tend to have more fire.

The Cushion cut is square-ish with soft,pillow-like edges and corners. It is unique as it is one of the only diamond cuts that carries elements of roundness as well as geometric lines. It is a brilliant cut meaning that it has triangular and kite shaped facets. It sparkles beautifully and sometimes they face up a little bit bigger than Princess cuts.

One of the really good aspects of the marquise cut is you can set it either vertically or horizontally or even as accent side stones alongside other shapes. Most solitaire marquise diamond rings have the marquise cut diamond set in a vertical fashion , a north to south setting being the most traditional and common.

About 15% of engagement rings use Oval cuts so they are still a pretty special choice yet one that is becoming more popular than historically. They have been in vogue with some big stars in recent years making them somewhat of a popular choice for their followers.

This cut works best on diamonds of half a carat and above. The beauty of this shape is more pronounced in larger stones . The symmetry in a heart shape diamond is so important that it cannot be understated must look for a diamond where the two halves of the heart are identical and the heart's cleft is distinct and even. You can imagine how much skill goes into this cut with only master diamantaires having the ability to produce such exquisite pieces.

This is very much a personal choice . Oval shapes are available in all sorts of shapes from rounder to thinner . Please look at the ratios on the GIA Certificate to understand the shape in more detail. The ratio is an important measure...this shows the length divided by the weight . You should consider your finger width and length when choosing an oval cut diamond .

They are as popular as ever...often used as side stones on engagement rings they complement other diamond shapes and jewelry in an almost majestic way . One look at their sleek and sophisticated style will take you back to the clean lines and geometric shapes of the Art Deco period. They are incredibly popular in diamond bands and look both contemporary and vintage.

The reason that Baguette cuts are more expensive generally is because they are more difficult to cut from the rough .

For hundreds of years the heart shape has been a popular diamond cut . Heart shaped diamonds were often used as gifts between royalty as a sign of friendship . And today there has been somewhat of a resurgence in wearing heart shaped diamonds especially in the Far East.

As the name suggests, oval diamonds are symmetrical,elongated rounded shapes which possess a similar level of fire and brilliance to that of a round diamond.

On average a Cushion cut diamond should cost atleast 25% less than a brilliant round cut.

The Marquise cut is steeped in history and dates back to the 18th Century in Paris. Romance is at the heart of this cut...King Louis XV was passionately involved with the Marquise de Pompadour , a rather beautiful lady by all accounts. King Louis struggled to contain his passion and was a true French romantic and in the heat of his love for the Marquise demanded that his jewellers cut diamonds to resemble her lips , which clearly they 'jumped to' hoping to avoid execution or even worse. Hence, the Marquise cut was born.

In a similar way to the emerald cut they are not cuts that focus on their brilliance and sparkle , rather it is their rectangular shape with the step-up cuts and open tables that make them popular.

The 'word' baguette is a French word for a long, narrow loaf of bread popular today around the world. The Baguette cut is representative of this loaf of bread...rectangular, long , and narrower proportionally than other cuts.

Yes this cut requires tremendous skill to make the diamond look really wonderful . Precision of the cut is critical to create a perfect gem.

As you may have guessed the emerald cut for diamonds originated from the shape used to cut emeralds themselves. It is an elegant shape and has a very long history stretching back over 700 years with earliest records showing it became popular back in the 14th Century. An Emerald Cut diamond usually has 57 facets with an elongated rectangular shape and cut-off corners .

It all comes down to an individual's taste. The positives are its size, cost, and style. If one buys an elongated shape, pear cuts look larger than a round diamond. However, you must consider the length of your fingers if this is for a ring design. But the size benefit is true...they are actually in the region of 8% larger on the top surface for the same weight round diamond.

When choosing a Hearst shape you must look very carefully at the overall shape and the symmetry of the cut and the curves. The ratios are particularly important in a heart shape ... a little trick is to look for a heart shape that is as tall as it is wide . These are the ideal shapes to wear.
