Choosing the perfect diamond for your engagement ring can be a tough decision, but it is important for you to find the perfect one. The main elements to consider are the shape and size and the four C’s, which follow in order, Colour, Clarity, Cut and Carat Weight. In order to help you find the perfect diamond, we have put together a simple outline to help you meet the criteria and help you make an informed decision

Diamond Choices – The shape

More than half of engagement rings feature round brilliant cut diamonds. They are the most popular diamond shape, due to the simplicity and elegance. The reflection and refraction of light is maximised in this cut. The scintillation compared to other shapes is incomparable. Round diamonds are timeless and classic.

Alternatively, you may prefer a fancy shaped diamond. Not only are they divine and distinctive, you can get them in any size and carat weight. If you are intrigued with these brilliant shaped diamonds, take a look at the princess cut, cushion or radiant cut. Princess cut diamonds are crafted meticulously, into a square shape that gives them a beautiful modern edge that looks dazzling in a striking setting to compliment.


Cushion cut diamonds are sitting more on the traditional side, with their softened corners, they are an admirable choice if going more for the vintage style. Lastly, radiant cuts. Radiant cut diamonds combine chic rectangle shape of a beautiful emerald cut with an amazing sparkle. For an elegant yet dramatic look, asscher cut diamonds are the best choice. They give out an amazing refined mirror like shine from their large polished and clean facers. If you really want to go for something different, ovals, marquise and pear shaped diamonds would be perfect. These stones are stunning, these diamonds make the most of the size and flatter the hand.

The Size

After picking out a beautiful diamond, the next step which comes into the process is the size and quality. When considering the size of a stone, you need to think about the carat weight you are considering. The carat is the weight of the diamond. All diamonds are have different weights, you can get them in different weights. The way jewellers and gemologists grade a diamond is by assessing the four C’s, which are carat, colour, clarity, cut and weight. We have spoken about the carat weight in the previous section, so lets discuss the next 3.



Next to the shape of the diamond is the colour. The colour of the diamond is important, this is what you will see first when looking at the stone. The colour is what determines how white the diamond is. D,E or F colour is where we advise to aim for (colourless). Colour will give you that ever lasting beauty. A diamonds colour is the diamond. The lower the colour the more off white the diamond will be. We do advise to stay nearer to the colourless section, please contact us for a comparable viewing.



Clarity is another diamond aspect which is graded on the scale. This time starting from FL (Flawless) to I1-I3 (Included). Clarity refers back to the blemishes and inclusions present in an individual diamond. The blemishes and inclusions are difficult to see with a naked eye and also difficult to see with a times ten loupe. Flawless diamonds are extremely rare, therefore increasing the price. VS1/2 or SI1 is often where you would want to be, they have very small inclusions.

Precious Metals

One of the most important things when choosing an engagement ring is choosing the metal. There is a vast range to choose from, we pride ourselves in using top quality metals, i.e, 18CT yellow gold, white gold and rose gold, alongside using 950 platinum. All our metals are fully British hallmarked.

18K White Gold

18CT white gold has a similar appearance to platinum, it is a lustrous silvery white, making it another spectacular choice for jewellery. White gold is naturally a yellow colour. White gold is an alloy of gold. It is made up of pure gold, mixed with alloy metals that have a silvery-white colour, such as palladium and silver.

18k Yellow Gold

18CT yellow gold is a beautiful and lustrous gold, it is boasts the richness of the colour. Yellow gold is 75% of fine gold and the other 25% is of other metals, adding strength to make it suitable durable for an everyday wear. 18K yellow gold, alongside with 18K white gold and 18K rose gold, follows a similar price point.

18K Rose Gold

Pure gold is alloyed with copper to produce the rose colour. The more copper used, the redder the gold appears. A common mix—or alloy—for rose gold is 75% gold and 25% copper by mass (18K). Like white gold, since rose gold is an alloy, “pure rose gold” doesn’t actually exist.
