Your Ultimate Guide to Choosing the Perfect Diamond for Your Dream Engagement Ring

Your Ultimate Guide to Choosing the Perfect Diamond for Your Dream Engagement Ring

Embarking on the journey to find the ideal diamond for your engagement ring involves understanding the Four C's: Colour, Cut, Clarity, and Carat, which I know can feel a little overwhelming especially when you're not sure which one is the most important.
Let's explore each of these aspects in depth, allowing you to make a well-informed decision to choose the perfect diamond that is a balance of size and quality for your bespoke engagement ring.

As you embark on your diamond quest, the diamond's colour is an important factor to consider. Opting for a white diamond is the traditional choice, which exudes timeless elegance. Looking for a diamond without any yellow tint is most often desired as we associate diamonds with being white and bright. Typically, diamonds within the D to G colour range are those that I would suggest for the best white appearance. However, for larger stones, don't disregard H or I colour diamonds as they can be budget friendly way of achieving the size of diamond you desire, and as long as we choose a well cut diamond they will still look white when set into your solitaire or halo ring.
There are always the options for coloured diamonds too, which can give a unique look to a timeless design. The price of coloured diamonds does vary hugely, with those most rare such as Pink Diamonds being much more expensive than other coloured diamonds such as yellow, chocolate or cognac. However all colours of diamonds when set within the design to suit their colour and shape can look fantastic.

Clarity is an attribute that speaks to a diamond's internal characteristics. Often called nature's fingerprints, these inclusions influence a diamond's uniqueness. Most people are looking for a diamond which doesn't have any obvious inclusions as they want their engagement ring to be clear and full of sparkle, however heavily included diamonds often called "Salt & Pepper Diamonds" have recently become popular for their unique appearance as well as being much more budget friendly. If you are looking for a diamond without any marks visible to the naked eye we would suggest a diamond with clarity grades between Flawless and VS2 to guarantee a breathtaking gem. If you are looking to maximise the value in your diamond and want as large a stone as possible we would also suggest to look at some SI clarity diamonds when they have a brilliant cut such as a round or oval shaped diamond.

Beyond the shape of the diamond lies its cut – a testament to the skill of the diamond cutter. This factor is the only one influenced by human expertise. The cut intricately defines a diamond's brilliance, fire, and overall visual appeal. Opting for a well-cut diamond is akin to choosing a masterpiece that maximises its innate potential to radiate light. A well cut diamond has the perfect proportions to allow the light to travel through the stone and bounce back to create the ultimate sparkle. 
Cut can also be used to create an unusual element to your gemstone, such as using traditional techniques such as rose cutting or emulating the antique cutting styles of vintage diamonds.

Carat, often associated with size, is actually a measure of a diamond's weight. The cut influences how a diamond presents itself in terms of size. Exceptional cutting techniques can make a diamond appear larger or more substantial than its carat weight would suggest. The shape of a diamond can also make it appear larger than other shapes of similar sizes, for example a Pear shaped Diamond will almost always look much larger on the finger than a Round Diamond of the same Carat weight.

Diamond Shape
The shape of a diamond significantly influences your choice. For instance, if your heart is set on an Emerald Cut, be mindful of its large step-cut facets, which can show inclusions off more obviously and so demand a higher clarity grade to maintain it's clear appearance. We would suggest VS1 as a minimum clarity on an Emerald cut Diamond Engagement Ring. On the other hand, brilliant cuts like round, cushion or oval have the magical ability to mask inclusions due to their facet placement and fiery sparkle.
If you were looking to maximise the size of stone for your budget you could get away with a good SI1 or sometimes SI2 stone and still have a diamond which looks completely clear to the naked eye.
