What Diamond Shape Is The Most Expensive?
As a leading jewelry store with a passion for quality and customer satisfaction, we've created this guide to help buyers understand the significance of the shape of a diamond when determining its price.

The 4Cs of Diamond Grading: Carat Weight, Cut, Clarity, and Color

When determining the price of a diamond, four factors are considered, known as the 4Cs of diamond grading: 
  • Carat weight 
  • Cut 
  • Clarity 
  • Color
These factors significantly influence the value of a diamond. A larger diamond will have a higher carat weight and therefore, a higher price. The cut of a diamond determines its brilliance and sparkle, making it an essential factor in determining its price. Clarity refers to the number and size of inclusions or imperfections in the diamond.  Color refers to the absence of color in a diamond. The more colorless the diamond, the higher its price.

Other Factors that Affect Diamond Prices

  • Certification 
  • Fluorescence 
  • Market demand 
These are all additional factors that can affect diamond prices. A certified diamond from a reputable organization like the Gemological Institute of America (GIA) may command a higher price. Fluorescence, or the diamond's reaction to ultraviolet light, can also affect its price. Some diamonds with strong fluorescence may be less desirable and, therefore, less expensive. Market demand can also influence diamond prices, with certain shapes and sizes becoming more popular at different times.

Understanding Diamond Shapes

Diamonds come in ten primary shapes, each with unique characteristics and popularity. The round brilliant cut is the most popular and often considered the classic diamond shape. Other popular shapes include: 
  • Princess 
  • Emerald 
  • Cushion cuts
Less common shapes include:
  • heart 
  • pear 
  • marquise

Ranking of Diamond Shapes by Price

The ranking of diamond shapes by price can vary depending on market demand, but generally, the round brilliant cut is the most expensive. The cushion and oval cuts are also considered expensive, while the pear and marquise cuts are typically less expensive. The ranking can be influenced by various factors, including the shape's popularity, rarity, and demand.
