A major decision that you will be faced with in selecting the right diamond for that special someone is the question of shape, or cut. There are many, many different and unique shapes available in today’s market. Determining the right one to suit your expectations can be very difficult.
In general, choosing which shape you want is really a question of personal preference. What shape visually appeals to you the most? However, every shape has different optical characteristics, so if you are seeking a specific property, such as brightness or fire, some diamond shapes may fit your criteria better than others. The traditional shapes are:
Round
Traditional Round Diamonds
The traditional round diamond has 57/58 facets, 57 without a Culet and 58 with a Culet. This is the traditional pattern that has been cut for about a hundred years. As time has passed, the precision with which the pattern is cut is about the only thing that has changed. The pattern is still the same.
When looking to purchase a traditional round, the goal is really to get a diamond that is balanced. Seeking optimal light performance in a traditionally cut stone is not a good approach and is going to leave you frustrated. What you want to be looking for is a good value for the weight, color, clarity, and cut.
You can definitely find a traditional diamond that will have a beautiful appearance. Many of the “old timers” of the industry still love what is known as the 60/60 diamond, meaning that the diamond has a 60% Depth and a 60% Table. These stones tend to be bright and glittery.

It is common for couples seeking traditional diamonds to find stones that are very shallow in an effort to obtain a “spready” stone, or one that looks bigger than its weight. This is ok, so long as the customer understands that the shallow depth will cause the diamond to sacrifice brilliance.
