Diamond Shapes and Sizes

Available Diamond Shapes

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

•     Round diamonds


•     Emerald diamonds


•     Heart diamonds


•     Princess diamonds


•     Pear diamonds


•     Radiant diamonds


•     Asscher diamonds


•     Marquis diamonds


•     Oval diamonds

Two diamonds that are the same shape will appear to look slightly different depending on the size 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 tremendously 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 picking 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 attractive 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 tough.  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 desire to have a heart shaped diamond.

Other concerns 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 clumsy .  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 common.
