If you haven’t already, read part one of our two-part series on the names and meanings of various diamond shapes. We have seperated these posts because it is important to the history of diamonds to proceed at a snail’s pace to gaining knowledge.
With diamond gem shapes and cuts there is everything from Radiant Diamonds, Pear, Oval, and Marquise-cuts, there is nothing like an uncut rough diamond. If you are confused about the kind of diamond shape you want, there are a range of options from which you can choose that may have more artistic appeal to you, rather than just monetary cost.
- Radiant cuts are rectangular brilliant cuts that have 45 degree corners. They are similar to princess cuts but have a slightly different faceting pattern. They also can appear similar to cushion cut diamonds when set into rings.
- Pear cuts are a very classical shape which have been regaining popularity in recent years. It is important to choose a pear that has good shape-appeal. We don’t want pears that appear too wide or too long. To find this ideal shape we assess the length-to-width ratio. Ideally it should be between 1.5:1 and 1.65:1
- Oval cut diamonds are one of the most popular shapes currently. They tend to be shallower with a larger face to weight ratio. This makes them appear larger than their carat weight would suggest. This makes an attractive option to many of our clients.
- Marquise-cut diamonds creates the illusion of a diamond larger than its actual weight.
There is no ‘ideal’ depth and table parameters for fancy cut diamonds since these percentages will vary based upon the unique length, width, and depth measurements of each stone.
While much has been written about the optimal depth and table percentages for diamond cuts, the conclusive study by the Gemological Institute of America (https://www.gia.edu/) clearly indicates that maximum brilliance is produced in round diamonds with depth and table percentages very close to 60%.
