Selecting the Perfect Diamond
How to choose the perfect diamond? There are a host of factors to consider when buying a diamond. From the Four Cs – cut, carat, clarity and colour – to diamond shapes, certification and ethical diamond sourcing; our diamond guides shed light on the art of selecting your perfect diamond.
Why Choose a Diamond from Pragnell?
Every Pragnell diamond is hand selected by a Pragnell family member.
As a sixth-generation, family-owned British business with a rich and royal heritage, we have built strong and trusted relationships with renowned diamond cutting houses.
Our wealth of experience and education enables us to work with the cutters to identify diamonds that perform beyond the certification they have been given. Each diamond is assessed on its performance: a combination of three components, scintillation, fire and brilliance; these are what give the diamond its super sparkle.
By assessing each diamond in this way, we are able to select the best performing diamonds for the best value, savings which are then passed on to our customers.
Diamonds: The Four Cs
Cut, colour, clarity and carat: find out more about what they are and how they can help you choose your perfect diamond.
Every certified diamond comes with a unique report, which lists its carat weight and cut, colour and clarity grading, along with the precise measurements of that particular stone. The report includes a diagram of the diamond on which the size, shape and placement of any inclusions or blemishes are marked, along with information about the diamond’s polish, symmetry and fluorescence. This certificate is a guarantee that the stone is a natural diamond, and that it has been cut and polished in line with industry standards.
Diamonds can look the same on paper, but in reality, they can be quite different. At Pragnell, our gemmologists sift through thousands of diamonds, analysing each stone one at a time to find those whose quality and beauty reflect above and beyond their grading; all our diamonds are certified by GIA, IGI or HRD.
