The 4 Cs of Diamonds
Every diamond is defined by four key characteristics: cut, colour, clarity, and carat. Together, they determine how a diamond looks, reflects light, and wears over time.
Cut
Cut determines how a diamond reflects light. A well-cut diamond will appear brighter and more balanced, regardless of size.
Colour
Diamond colour is graded from colourless to slightly tinted. Stones with less colour tend to appear more crisp and refined.
Clarity
Clarity refers to natural inclusions within the diamond. Most are not visible to the eye but can influence overall quality.
Carat
Carat measures the weight of a diamond, not its size. The appearance of size depends on both carat and cut.
Natural and Lab-Grown Diamonds
Natural and lab-grown diamonds are both real diamonds, sharing the same physical, chemical, and optical properties. The difference lies in how they are formed.
Natural diamonds develop over billions of years beneath the earth.
Lab-grown diamonds are created in controlled environments using advanced technology, resulting in the same structure and appearance.
For many, lab-grown diamonds offer a more considered choice. They allow for greater flexibility in size and specification, while also reflecting a shift towards more transparent and responsible sourcing.
At FiftySeven Jewellery, we work with lab-grown diamonds as part of a modern approach to fine jewellery, where design, quality, and conscious production can exist together.
Diamond Shapes
The shape of a diamond defines its overall look, how it reflects light, and how it sits within a ring. From classic round diamonds to more modern oval, pear, and emerald cut shapes, each brings a distinct feel to an engagement ring or custom jewellery piece.
Choosing the Right Diamond
If you’re unsure where to start, focus on what you notice first.
Cut plays the biggest role in how a diamond performs, followed by shape and overall appearance. Colour and clarity can often be balanced without affecting how the diamond looks when worn.
A well-chosen diamond is less about perfection and more about proportion, balance, and how it feels on you.
