Every diamond is unique, yet its quality is assessed through four essential characteristics known as the 4Cs: Cut, Colour, Clarity, and Carat. Together, these qualities determine how a diamond looks, how brilliantly it performs, and how its value is understood. At Diya Jewel, we guide every client through these factors with clarity, care, and expert attention.
Cut Diamonds
The cut of a diamond is one of the most important factors in its beauty and brilliance. Unlike shape, such as round, oval, or princess, cut refers to how precisely the diamond's facets are proportioned, polished, and aligned to reflect light.
Why Cut Matters
- Brilliance and Sparkle A well-cut diamond captures light and reflects it back through the crown, creating the lively sparkle that makes diamonds so captivating.
- Fire and Scintillation Cut influences how light disperses into flashes of colour and how the diamond sparkles as it moves.
- Value and Quality Even a diamond with excellent colour and clarity can appear dull if it is poorly cut. Cut is the quality that brings a diamond to life.
Cut Grades
- Excellent or Ideal Designed for maximum brilliance, fire, and balanced proportions.
- Very Good Strong sparkle with only slight differences from the finest cut grades.
- Good Attractive brilliance, though less lively than higher cut grades.
- Fair or Poor Limited sparkle, often because light escapes rather than reflecting back to the eye.
Key Elements of Cut
- Proportions The relationship between depth, table size, and angles.
- Symmetry The precision of facet alignment and overall balance.
- Polish The smoothness and finish of each facet surface.
In simple terms, cut is the soul of the diamond. It transforms a piece of carbon into a jewel that shines with timeless beauty. At Diya Jewel, we select diamonds cut for brilliance, elegance, and lasting presence.
Colour of Diamonds
Diamond colour refers to the natural tint present within the stone. Truly colourless diamonds are rare and highly valued, while most diamonds carry subtle traces of yellow or brown. The less visible colour a diamond has, the higher its colour grade and the brighter its appearance.
Colour Grades
- D-F: Colourless Exceptional quality with icy brilliance and rare purity.
- G-J: Near Colourless Slight warmth that generally appears white to the eye, offering excellent beauty and value.
- K-M: Faint Colour Noticeable warmth, often chosen for vintage-inspired or yellow-gold designs.
- N-Z: Light Colour Visible yellow or brown tones, typically less valuable than higher colour grades.
Why Colour Matters
- It enhances the diamond's sense of brightness and purity.
- It affects how the diamond pairs with metals such as platinum, white gold, yellow gold, and rose gold.
- It influences rarity, value, and the overall character of the jewellery design.
At Diya Jewel, we carefully select diamonds with colour grades that suit both the design and the client's preference, ensuring every piece radiates refined elegance.
Clarity of Diamonds
Diamond clarity measures the presence of internal features, known as inclusions, and external marks, known as blemishes. Because diamonds form under intense natural conditions, these characteristics are common. The fewer and smaller they are, the higher the clarity grade.
Clarity Grades
- FL / IF: Flawless or Internally Flawless No visible inclusions under magnification.
- VVS1-VVS2: Very Very Slightly Included Minute inclusions that are extremely difficult to detect.
- VS1-VS2: Very Slightly Included Minor inclusions that are difficult to see and often invisible to the naked eye.
- SI1-SI2: Slightly Included Inclusions visible under magnification and sometimes noticeable without it.
- I1-I3: Included Obvious inclusions that may affect brilliance, transparency, or durability.
Why Clarity Matters
- It determines the diamond's visual purity and transparency.
- It can influence how light travels through the stone.
- It affects both beauty and value, especially when inclusions are visible.
At Diya Jewel, we balance clarity with cut and colour so every diamond offers excellent beauty, brilliance, and value.
Carat Weight
Carat measures the weight of a diamond and is often associated with size. While higher carat weights are rarer and more valuable, a diamond's visible presence also depends on its cut, shape, and setting. A well-cut diamond can appear more impressive than a heavier stone with weaker proportions.
Our specialists help you choose a carat weight that feels balanced on the hand, complements the design, and aligns with your budget.

The 4Cs work together to create a diamond's true character. At Diya Jewel, we carefully select and craft each stone so it embodies brilliance, elegance, and enduring beauty, truly Yours Forever.
