Diamond Shapes

Available Diamond Shapes

If you thought all diamond shapes were the same, you may be surprised at the abundant number of diamond shapes that are available. Most jewelers offer at least nine of the most common gemstone shapes, including:

Diamond Shapes

Two diamonds that are the same shape will appear to look slightly different depending on the siz and weight of the diamond, as well as the type of setting that the stone is placed in. The same ring worn on two different hands can also look quite different, based on the size of the hands.

Difference Between Diamond Shapes and Diamond Cut

Many people mistakenly use the terms “diamond shapes” and “diamond cuts” interchangeably, but there is a difference between them. The cut of a diamond refers to how the artisan maximizes the features of the gemstone by creating angles and details, making the light go into the diamond and bounce back in the most brilliant way possible. The quality of a diamond's cut contributes greatly to the overall value of the gemstone, where as the shape of a diamond does not increase or decrease a diamond's value. When discussing diamond shapes, you are referring to the actual geometric shape of the diamond, whether it is round or oval, emerald or heart shaped, for example.

Choosing Diamond Shapes

With all the possibilities of diamond shapes, how do you go about choosing one? If you are buying yourself a diamond, it's just a matter of looking at all the different varieties and finding one that is most pleasing to your eyes, and the ones that look best when you put them on your finger, or wear in your necklace.

When choosing a diamond shape for someone else, it becomes a bit more difficult. For an engagement ring, many women prefer the traditional round shaped diamond, while others may enjoy having something more unique. A young woman or one who is considered a hopeless romantic may prefer to have a heart shaped diamond.

Other considerations for selecting diamond shapes for rings should be based on the size of a woman's hand. If she has long, slender fingers, can elegantly wear a pear shaped diamond, marquis, or oval shape. Place the same shaped diamond rings on a woman with shorter, wider fingers, and it will cover up too much of the finger and look bulky, and perhaps even awkward. Small hands typically look best with round shaped or princess shaped diamonds.

Most Popular Diamond Shape for Engagement Rings

Even though there is a wide variety of diamond shapes available, the most commonly purchased diamond shape for engagement rings is the round diamond. Round diamonds are considered the “classic engagement ring”, and the stones are often set in yellow gold or platinum. In fact, any diamond shape other than round is considered to be a “fancy” shape, since the round diamond is so popular.

Diamond Cut

Our love of diamonds and admiration of their fire and brilliance has given rise to many different cuts of diamonds. While we still see some of the earliest styles of diamond cuts – such as the round and emerald-cut, there are many more cuts today, some of them patented by their designers and costing hundreds of thousands of dollars.

The most popular cut for a diamond ring today is still the round, brilliant cut. It was developed in the 17th century in Venice. It is still preferred when the raw crystal is in an octahedron formation. Even though as much as 50% of the stone is cut away in the process, often two stones can be carved from an octahedron. More unusually-shaped stones are used for fancy cuts, such as a marquise, pear or heart shaped diamond. The earliest brilliants had 17 facets on the top of the stone and were called double-cut. This was soon improved with stones cut with 33 facets and were called triple-cut brilliants.

Brilliant Round Cut

In the 19th century, with the development of better gem-cutting tools, more innovations in diamond cutting styles were developed. In 1919, Marcel Tolkowsky combined the art of cutting with the science of light and refraction and published his book, Diamond Design. These relatively recent geometric calculations were the forerunner of much of diamond cutting work today and led to other, more precise mathematical models engineered to enhance the fire and brilliance of diamonds.

There are now cuts such as the princess cut, trillions, ovals, pear and heart-shaped. Some innovative cutters have even fashioned star or butterfly-shaped diamonds! One patented cut, the Ashoka diamond, is an oblong cut with rounded, brilliant ends, and requires a stone 3 carats or larger. It’s an exceptionally beautiful (and pricey!) diamond shape. Tiffany has also patented a cut of diamond called the Lucida cut. It’s the lucky bride whose fiancé gives her one of these highly coveted stones!

Diamond Certificates

Diamond certificates from independent organizations such as the Gemological Institute of America (GIA) provide a diamond grading report, that gives you valuable information about the 4 C's that were taken into consideration when the diamond was priced. It's important that you use an outside source for diamond certificates, instead of the jeweler who is selling the diamond you are interested in, because the jeweler wants to make money on the sale of the diamonds, the certificates may be slightly biased and you could be paying more than the market value of the diamond.

Reasons to have Diamond Certificates

When you go to a jewelry store, or consider making a purchase from an online retailer, the jewelry that has diamond certificates tends to sell for several hundred dollars more than diamonds that are graded the same that are without certificates. This is because the jeweler recognizes that they typically grade their diamonds one level better than an independent grading organization, like the Gemological Institute of America. The GIA is more conservative when grading diamonds because they do not gain anything from diamond sales.

Pay the Right Price for your Diamond

Diamonds are valued according to their quality based on a grading system that makes use of the 4 C's. You should receive diamond certificates (also called grading reports) from independent companies rather than a jeweler, to insure that your getting an unbiased reporting of the value of the diamond. Otherwise, you could be paying much more for your diamond than what the diamond is actually worth.

Protecting Your Investment

Diamonds are not the same kind of investment as buying stocks and bonds, but having diamond certificates gives you a better investment than just having the diamond. Diamond certificates make it easier to sell a diamond in the future, because you have documentation of how much the diamond is worth and why it was valued that amount. In fact, if you attempt to sell diamonds without having diamond certificates, most dealers will not buy from you and you would end up having a certificate drawn up anyway, so you may as well have a certificate grading report created at the time of purchase, for your current protection as well as future possibilities for selling.

Increased Security during Cleanings and Repairs

Many people hesitate to bring their jewelry into the jeweler's when they're in need of repair services or cleaning. It makes people wonder how they'll know for sure that they've received the same diamond back that they brought in. It is an extremely rare occurrence for a jeweler to purposely switch diamonds, however it could happen unintentionally. Diamond certificates act as an additional security measure in this case. They are like fingerprints stored in police databases, they contain all the data needed to match the person to the fingerprints, and diamond certificates have enough information on the diamond to match the diamond with the certificate and the owner.
