The 4Cs of Diamonds Explained: Colour, Clarity, Cut, and Carat

At Yarra Jewels, we guarantee beauty, value, and authenticity; we meticulously choose only the best diamonds.
For exceptional brightness and a pure white appearance, we choose diamonds in the D–E–F colour range. Our diamonds, which are nearly perfect to the unaided eye, are graded VVS1, VVS2, and VS1.
These colour and clarity combinations provide the ideal ratio of authentic pricing to luxury. For total transparency, each diamond we use has a 100% IGI or GIA certification.
You may confidently cross-verify because every specification is stated in detail on the certificate.
What are the 4Cs of Diamond?
COLOUR
The term diamond colour describes the inherent hue of a diamond, which is rated from D to Z, with D being the rarest and most colourless.
Classified as colourless, D–E–F diamonds give the highest degree of clarity and brilliance; even up close, they seem bright white.
At Yarra Jewels, we only use D, E, and F-coloured diamonds to provide optimal shine, elegance, and aesthetic excellence.

The faint warm tone of G–H–I–J–K–M diamonds can be seen in some lighting situations.
N–R diamonds have a distinct colour and are usually seen in jewellery that is more affordable.
S–Z diamonds are regarded as lower on the colour scale and have a distinct yellow or brown hue. Outside of the D–Z grade, fancy yellow diamonds are prized for their deliberate, deep yellow hue as opposed to their colourlessness.
You may confidently cross-check the quality and authenticity of your diamond because all diamond colour gradings are independently certified and prominently displayed on IGI or GIA certificates.
CLARITY
The natural inclusions, or minute internal features that occur when a diamond is generated deep within the earth, are referred to as diamond clarity. These entirely natural inclusions aid gemologists in determining a diamond's quality.
Professional graders use clarity grades to indicate how noticeable these inclusions are at 10× magnification. VVS1, VVS2, VS1, VS2, SI, and I are the primary clarity grades.
Even with magnification, the minuscule inclusions of VVS1 (Very Very Slightly Included 1) diamonds are practically undetectable. With tiny inclusions that are still undetectable to the unaided eye, VVS2 diamonds are very comparable.

Very tiny inclusions may be present in VS1 (Very Slightly Included 1) diamonds, but they are never apparent to the unaided eye. These grades are regarded as premium diamonds because they have remarkable clarity and brightness when viewed in person.
At Yarra Jewels, we only employ VVS1, VVS2, and VS1 diamonds. Our diamonds are clear, brilliant, and perfect to the unaided eye. Our goal is to provide only high-quality diamonds that combine long-term satisfaction, beauty, and value.
You may confirm authenticity, quality, and grading with total transparency and confidence because all diamond clarity details are explicitly stated on IGI or GIA certificates.
CARATS
Diamond carat refers to the weight of a diamond, and it directly influences its size and visual presence. Even at the same carat weight, different diamond shapes have varied millimetre (mm) measurements, which are displayed in the chart for convenience.
We provide a variety of carat alternatives in different forms so you may select the one that best suits your taste and price range. The choice of carat size can be influenced by the jewelry’s overall balance, style, and personal taste.
Additionally, we provide custom-made solutions that allow you to precisely customise the carat size and specs to meet your needs.

CUT
Diamond cut refers to how well a diamond has been shaped and proportioned. Cut directly affects how light enters, reflects, and exits the diamond. A well-cut diamond delivers superior brilliance, fire, and scintillation. Even high-colour and high-clarity diamonds can appear dull with poor cut quality.
Diamond cut is graded based on proportions, symmetry, and polish. Excellent and ideal cuts maximise light performance and visual sparkle. A precisely cut diamond appears brighter and more visually striking.
At Yarra Jewels, we carefully select diamonds with exceptional cut quality. Our diamonds are chosen to ensure optimal light return and balanced proportions. This attention to cut enhances overall beauty and long-term visual appeal.
All cut grades are independently assessed and stated on IGI or GIA certificates. You may confidently verify cut quality as part of the diamond’s complete certification.
