Diamonds come in a variety of cuts, each with its own unique characteristics that affect the diamond's appearance and brilliance. The cut of a diamond refers to how well it has been shaped and faceted. The cut is one of the "Four Cs" used to assess the quality of a diamond, along with carat weight, colour, and clarity. Here are the main types of diamond cuts:

  • Round Brilliant Cut: This is the most popular and classic diamond cut, known for its exceptional sparkle and brilliance. Round diamonds have 57 or 58 facets, including the table, crown, girdle, and pavilion. The proportions and angles are carefully calculated to maximise the reflection and refraction of light within the stone.
  • Princess Cut: Princess-cut diamonds are square or rectangular with pointed corners. They have pointed corners and are known for their sharp, clean lines. When well-cut, they offer excellent brilliance and sparkle.
  • Emerald Cut: Emerald-cut diamonds are rectangular with cut corners, and they have a step-cut faceting style. This cut emphasises clarity over sparkle and is known for its elegant and timeless appearance.
  • Asscher Cut: Similar to the emerald cut, the Asscher cut is also a square or rectangular step-cut diamond with cut corners. It has a vintage and art deco appeal and is prized for its clear, mirror-like facets.
  • Radiant Cut: Radiant-cut diamonds combine the elegance of the emerald cut with the brilliance of the round brilliant cut. They are typically square or rectangular and have cropped corners.
  • Oval Cut: Oval-cut diamonds have an elongated, oval shape. They are known for their brilliance and the illusion of greater size due to their elongated appearance.
  • Marquise Cut: Marquise-cut diamonds are elongated with pointed ends, resembling the shape of a rugby ball. This cut maximises the diamond's surface area, making it appear larger than its carat weight would suggest.
  • Pear Cut: Pear-cut diamonds, also known as teardrop diamonds, are a hybrid of the round and marquise cuts. They have one pointed end and one rounded end, creating a unique and elegant shape.
  • Heart Cut: Heart-shaped diamonds are a symbol of love and romance. They have a cleft in the top and a rounded bottom. Achieving a symmetrical heart shape can be challenging, making precision in cutting essential.
  • Cushion Cut: Cushion-cut diamonds are square or rectangular with rounded corners, resembling a pillow or cushion. They are known for their vintage appeal and a balance between brilliance and clarity.
  • Baguette Cut: Baguette-cut diamonds are long and rectangular with step-cut facets. They are often used as accent stones in jewellery, particularly in settings where their straight lines complement other shapes.
  • Trilliant Cut: Trilliant-cut diamonds are triangular in shape and are often used as side stones or accent stones in jewellery designs. They can also be used as centre stones for unique engagement rings.
  • Rose Cut: The rose cut is a historical cut characterised by a flat base with a dome-shaped crown covered in triangular facets. It has a vintage, antique look and is known for its unique style and softer sparkle.

Each of these diamond cuts has its own appeal and is suited to different styles and preferences. When choosing a diamond, consider not only the cut but also factors like colour, clarity, and carat weight to find the perfect balance for your desired appearance and budget.
