Diamond prices are not only affected by the shape type (i.e. pear, marquise, round, etc.), they're also affected by the attractiveness of the chosen shape. For example, an unsymmetrical or a long and skinny marquise diamond can't command the same price as a well-shaped marquise. The following diagrams show desirable shape outlines of five basic shapes. A knowledge of the ideal round shape is assumed. If you are buying a diamond for your own personal pleasure, its shape doesn't matter, as long as...

The shape of a diamond can play an important role in determining its price. For example: ♦ A 0.07-carat square may cost up to 20% more than a round diamond of the same weight, color, and quality. ♦ A 1-carat colorless round diamond might cost 15%-30% more than a one-carat square diamond of the same color grade and quality. ♦ A 1-carat intense-yellow round diamond can cost from 10 % to over 100 % more than a radiant with the same weight and color grade, depending on the stones and the dealer sell...

In this article I will elaborate what factors are considered in pricing diamonds as mentioned previously here when we talked about 4C diamond evaluation system.  CUT QUALITY: (Proportions and finish, also called make): This is a crucial factor which can affect prices by as much as 50 % .Two of the main considerations of cut are:  1.

Is 4C System Adequate When We Price Diamonds?

There are seven basic price factors for diamonds:  ♦ Cut quality (Proportions and finish) ♦ Colour ♦ Carat weight ♦ Clarity (Degree to which a stone is free from flaws) ♦ Cutting style & stone shape ♦ Transparency ♦ Treatment status (Untreated or treated? What type of treatment?) Why the 4C's is Not an Adequate Pricing System? You may be surprised that there are more than four price factors if you've heard about the 4C's of color, cut, clarity and carat weight. The 4C's system of valuing gems is...

Please note: From this post I will put all figures and tables in the end of each article. The two concepts of shape and cutting style are often described by one term in the jewelry trade. For example, when a jeweler uses the term baguette, he's referring to a squarecomered, rectangular-shaped diamond with rows of step-like facets (Figure 6). If the two long sides of the baguette taper inward, it's called a tapered baguette (Figure 5 & 8). The GIA has simplified the description of diamond cutting...

The shape of a diamond not only affects how big and brilliant it looks, but it may even reveal personality traits of the buyer. Saul Spero, a New York diamond appraiser and gem consultant, spent twenty-five years interviewing over 50,000 people and developing a system of predicting personality types mainly based on a person's first three preferences of diamond shapes. In his book Diamonds, Love & Compatibility, Spero discusses the six basic shapes-round, oval, pear, heart, marquise and square or...
