Diamond Colour
Choosing the Perfect Diamond Colour
At Cranstone Custom Jewellery, we understand that selecting the right diamond colour is essential to finding a piece that reflects your style and sophistication. To help you make an informed decision, the diamond industry has established a standardised grading system, starting with Grade D (the highest quality), denoting a complete absence of colour, and ending with Grades N through Z, which display noticeable colour.
Understanding Diamond Colour Grades
Diamonds are evaluated for colour based on the presence of chemical impurities or structural defects that can cause visible tints. The less colour a diamond has, the more brilliant and valuable it becomes. Diamonds graded between D and F are considered colourless, offering unmatched purity and light performance, while those graded lower may display varying degrees of noticeable colour.
| Grade | Description | Details | 
| D, E, F | Colourless | The highest quality diamonds, completely clear with no detectable colour. | 
| G, H, I, J | Near Colourless | Slight traces of colour, visible only to a trained gemmologist. Excellent value while maintaining brilliance. | 
| K, L, M | Noticeable Colour | Faint colour visible to the naked eye but still showcasing a captivating fire. | 
| N – Z | Noticeable Colour | Obvious colouration, often appearing yellow or brown. Cranstone Custom Jewellery does not carry these grades due to their lower quality. | 
Colourless Diamonds
- D – Grade D diamonds are the rarest and most sought-after, exhibiting pure brilliance with no detectable colour.
- E – Grade E diamonds have minute traces of colour that are nearly impossible to detect, ensuring exceptional radiance.
- F – Grade F diamonds display subtle colour traces, visible only under professional examination, yet still deliver superior brilliance.
Near Colourless Diamonds
- G, H – These diamonds appear colourless to the untrained eye, offering a balance of value and visual perfection.
- I, J – Diamonds in this range may have slight hints of colour but remain an excellent value with impressive sparkle.
Noticeable Colour Diamonds
- K, L, M – Diamonds in this category exhibit more noticeable colour but still possess captivating fire and charm.
Our Expert Advice
While diamond colour affects price, it is not the sole factor to consider when choosing a diamond. For those seeking value without compromising on appearance, G through H diamonds are an excellent choice, as they maintain a near-colourless look at a more accessible price point. In contrast, diamonds graded K or lower typically exhibit visible tints and are not offered by premium jewellers like Cranstone Custom Jewellery due to their lower quality.
A professional jeweller or gemmologist can guide you in selecting the perfect diamond to match your personal style and budget.
