Diamonds are available in a variety of differently shaped cuts.
The round brilliant cut diamond is by far the most popular choice worldwide. In 1919 Russian mathematician Tolkowsky calculated the theoretical proportions for this specific cut in such a way that 100% reflection (sparkle) is obtained. All round brilliant diamonds are polished according to these proportions. This classic shape is perfect for a diamond engagement ring or any other piece of jewellery. The round brilliant has been fashionable in the past, is fashionable today and will always be fashionable in the future. It remains a popular first choice.
The princess cut is fast becoming one of the most popular fancy shaped diamonds today. The face-up shape of the princess cut is square and its side profile is an inverted pyramid. Its unique shape and pointed corners put it in a different class than other shapes. Its unique, defining look is distinguishable from other shapes.
With its large pavilion in the lower half, the emerald cut shaped diamond has a unique style. Due to the large table it highlights the clarity of the diamond. Its rectangular shape sets it apart from other shapes in such a way that it is easily identifiable with the naked eye.
At first sight an oval cut diamond looks quite similar to a round brilliant. However, when looking at it more closely, one can see that it has longer sides and two sharper corners. When considering a ring this shape is excellent for a person who has long, slender fingers.
The marquise cut is a traditional shaped diamond which can be described as the "skinny" brother of the oval. This shape brilliance is further enhanced if surrounded by other shaped smaller diamonds. Carat for carat this unique shape has one of the largest crowns (upper half), making it a good choice to maximise the perceived size.
The pear, also known as the tear drop, is a traditionally shaped diamond which becomes wide as opposed to longer when the carat increases. This shape is more popular in pendants and earrings.
Carat (Ct) is the term given to the weight of a gemstone. Generally speaking the larger (heavier) the diamond, the more expensive it will be, however it is possible to purchase a larger diamond for less than a smaller one, provided a compromise is made with colour, clarity and cut.
Diamonds come in many different shades of colour. From totally white (D) to fancy yellow, green, pink or blue. Purchasing a diamond that has been certified by the GIA or HRD laboratories guarantees the colour, clarity, carat weight and cut.
Certified diamonds are usually slightly more expensive than non-certified stones. Diamonds as small as 0.25 carat are now available with certificates. Smaller diamonds set in eternity rings etcetera are not usually certified. Our standard non-certified diamond quality used in or rings and earrings is G colour and VS purity.
When a rough diamond is found it has spent millions of years evolving in the Earth. Nature is rarely perfect and a totally flawless diamond (IF) is a very rare thing. Most diamonds contain small natural imperfections called inclusions. These imperfections are graded and this partly determines a diamonds value. A diamond that has been certified by the GIA or HRD laboratories guarantees the clarity for that stone.
Minute inclusions, which are extremely difficult for a skilled grader to see at 10x magnification.

Inclusions are visible under 10x magnification and might be visible to the naked eye (particularly in the case of SI3).
The cut refers to the make of the diamond. All brilliant-cut diamonds have 52 facets or edges. Two diamonds of the same weight can look different in size. One might look dull compared to another. This is due to its cut. Certificated diamonds will detail the type of cut and symmetry.
This is the term given to a natural characteristic that occurs in some diamonds.
Under a UV light some diamonds will show a fluorescence.
This again can have an influence on the diamonds value.
By blending colour, clarity, cut and carat a diamond can be chosen that will fit any budget. With diamonds, size is not everything! However, the more money spent, the greater the choice in balancing quality and size of diamond.

Our jewellery is independently tested and hallmarked by the London or Birmingham Assay Office.
Since the Hallmarking Act of 1974, all our jewellery has been independently hallmarked by the British Hallmarking Council. This gives you the purchaser a guarantee of the quality and type of precious metal in our jewellery. All our jewellery carries our own Sponsors mark, Assay Office mark, Date mark, Common Control Mark and Metal Fineness mark.
Make sure before you buy jewellery that it has a proper independent hallmark like ours, otherwise you may not be buying what you think it is.
Our Cultured Diamonds are grown in a laboratory using the latest techniques and all our stones are Ethically and Environmentally friendly. Cultured Lab Grown Diamonds are less valuable than Natural Diamonds but cost significantly less allowing a Diamond to be purchased that is not only larger, but is also whiter in colour and higher in purity than its Natural equivalent.
Our Cultured Diamonds will be invoiced as Lab Grown Diamonds.
