The term "diamond shape" refers to the physical and visual shape of the diamond. Each shape has unique attributes influencing the diamond's overall appearance and brilliance. When purchasing a diamond, customers typically consider its shape as one of the primary factors.
Diamond cut and shape are often confused and used interchangeably, but they are two distinct concepts. Diamond cut refers to a diamond's proportions, symmetry, facets, and reflective qualities. On the other hand, diamond shape refers to a diamond's overall outline or external appearance when viewed from above.
There are various diamond shapes, each possessing its distinct characteristics. However, the round brilliant-cut diamond is the most popular and traditional shape. Additionally, there are fancy-shaped diamonds, including the princess cut, emerald cut, cushion cut, Asscher cut, pear cut, heart cut, oval cut, marquise cut, and radiant cut diamonds. These fancy-shaped diamonds are highly sought-after for engagement rings and fine jewelry due to their unique and breathtaking shapes.
Alternative shapes such as octagonal diamonds, trapezoids, baguettes, half-moon, and trillion-cut diamonds are gaining popularity recently because they create beautiful and distinctive designs.
The most popular and iconic shape of all time, brilliant round diamonds are the only perfectly symmetrical diamonds that offer an unmatched brilliance than any other shape. Round diamonds represent approximately 75% of all sold diamonds and have been researched (and developed) by gemologists more than any other diamond shape.
With nearly 60 facets, this shape boasts excellent light refraction properties and is renowned for its unrivaled fire and brilliance. Round-cut diamonds are a timeless and classic choice for diamond engagement rings and other jewelry, and round diamonds are more highly valued than other diamond shapes.
