Diamond Grading Explained: Cut, Colour, Clarity & Carat
Diamond grading is based on the internationally recognised 4 C’s: Cut, Colour, Clarity and Carat, which together provide a consistent and transparent way to assess a diamond’s quality and value. Each aspect plays a distinct role: cut influences brilliance and sparkle, colour measures how colourless the diamond appears, clarity evaluates natural inclusions or blemishes, and carat refers to the diamond’s weight. Using the 4 C’s ensures that diamonds are graded fairly and consistently, regardless of where they are bought or sold.
A professional diamond buyer uses the 4 C’s to determine both desirability and market value. Rather than focusing on size alone, buyers assess how these factors work together, as a smaller diamond with excellent cut and clarity may be more valuable than a larger stone of lower quality. By applying the 4 C’s, buyers can accurately price diamonds based on current market demand, ensuring a fair and informed offer when you sell your diamond or diamond jewellery.
How a Diamond Reflects Light
- The cut of a diamond determines how well it reflects light, directly affecting its brilliance and sparkle. A well-cut diamond will appear brighter and more valuable, regardless of its size or colour.
The Presence (or Absence) of Colour
- Diamond colour is graded on how colourless the stone appears, with less colour generally indicating higher value. Subtle colour differences can significantly influence a diamond’s worth.
Natural Inclusions and Imperfections
- The lion, anchor, and crown symbols are traditional UK hallmarks, showing the piece has been tested and verified by an official assay office. These marks are often found on silverware, cutlery, and antique silver items.
The Diamond's Weight
- Carat measures a diamond’s weight rather than its size. Larger carat diamonds are rarer and often command higher prices, especially when combined with strong cut, colour, and clarity grades.
Popular Diamond Cuts Explained
Round Brilliant Cut
The round brilliant cut is the most recognised and widely traded diamond cut, prized for its exceptional brilliance and balanced proportions. With 58 precisely aligned facets, it is designed to reflect the maximum amount of light, resulting in superior sparkle. This cut is often compared against all other diamond shapes when assessing quality, value, and performance, making it a benchmark in diamond grading and buying decisions.
Marquise Cut
The marquise cut features an elongated shape with pointed ends that enhances perceived size and creates an elegant, lengthening effect. Its unique silhouette allows buyers to achieve a larger visual presence without increasing carat weight. Precision in symmetry is essential for this cut, as it directly impacts brilliance and overall appearance.
Emerald Cut
The emerald cut is characterised by long, step-cut facets that produce a sleek, mirror-like effect rather than intense sparkle. It emphasises clarity and colour, making higher-quality stones especially desirable in this cut. Known for its timeless and sophisticated appearance, the emerald cut highlights a diamond’s internal structure and craftsmanship.
Pear Cut
The pear cut combines the brilliance of a round diamond with the elongated form of a marquise, resulting in a graceful teardrop shape. When properly proportioned, it offers excellent light reflection and a flattering appearance. This cut is versatile and suits both classic and contemporary jewellery designs.
Heart Cut
The heart cut is a distinctive and symbolic diamond shape that represents love and emotion. Achieving a well-defined heart requires expert craftsmanship, with even symmetry and proper cleft depth being critical to its beauty. This cut is valued for its rarity and individuality, often chosen for statement jewellery or meaningful gifts.
Princess Cut
The princess cut is a popular square-shaped diamond known for its sharp edges and vibrant brilliance. It delivers strong light performance while maintaining a modern aesthetic. Its cutting style allows for efficient use of rough diamonds, often making it a compelling option when balancing size, sparkle, and value.
Oval Cut
The oval cut offers a refined alternative to the round brilliant, delivering strong brilliance while appearing larger per carat. Its elongated shape softens the traditional round profile and reduces visible inclusions when well cut. This cut is appreciated for combining sparkle, elegance, and efficient use of carat weight.
Radiant Cut
The radiant cut combines the elegance of a rectangular or square shape with the brilliance of a round-style facet pattern. Its trimmed corners enhance durability while allowing strong light reflection, resulting in a bright, lively appearance. This cut is well-suited to diamonds set in both modern and classic jewellery designs and performs particularly well at masking inclusions, making it a versatile option when balancing brilliance, shape, and overall visual impact.
