What is a diamond shape?

A diamond shape refers to the specific cutting style that gives a diamond its distinctive appearance. In their uncut, natural state, diamonds possess a rather organic form that is transformed into the iconic diamond shapes that are widely admired. The round brilliant cut is the most classic diamond shape, while all other shapes, such as oval, cushion, and princess cuts, are known as “fancy shape diamonds.” Diamonds are crafted into two primary categories of shapes: brilliant cuts, which deliver exceptional sparkle, and step cuts, which highlight remarkable clarity.

Lab Grown Diamond Shapes: A World of Choices

Just as there is a diverse range of shapes available for natural diamonds, lab grown diamonds offer the same variety of shapes. Lab grown diamonds possess the identical optical, chemical, and physical properties as their mined counterparts. The only difference between the two lies in their origin, as lab grown diamonds are cultivated in a controlled laboratory environment using extreme heat and pressure.
IGI-certified lab grown diamonds are evaluated based on the same criteria as natural diamonds. When selecting a shape for a lab grown diamond, it’s important to choose the most suitable one for each specific stone. The goal is to minimize visible flaws or inclusions, which can also be present in lab grown diamonds. A skilled cutter will carefully study the stone to determine the ideal shape that maximizes both fire and brilliance while minimizing any visible imperfections.

The round brilliant cut remains the most popular choice for lab grown diamond shapes, as it offers unparalleled fire compared to other shapes. Another sought-after lab grown diamond shape is the oval, as it appears larger than its actual size and is currently in vogue. If you’re looking for an economical option that still provides an impressive appearance, consider marquise, pear, or cushion cut lab grown diamonds. These shapes result in less waste of the original stone. Similarly, Asscher and emerald cuts offer excellent value for their size.

Lab grown diamond roughs enable the creation of fancy shapes with ease, thanks to the precise control over the growing process. When selecting a lab grown diamond shape, consider your personal taste and budget to find the perfect match.
