Diamond Buying Guide

Getting clued up on Diamonds is a key factor in understanding what jewellery you are buying and determining if you are making the right choice. There are a variety of factors to consider including:

Finance
Occasion, style and suitability
Quality

By understanding what we call the 4 C’s, you will have gained the vital knowledge to make an informed decision incorporating all of the above factors. The 4 C’s all contribute to the value of the diamond.

The 4 C’s are:

Cut
Carat
Colour
Clarity


Cut

The cut simply refers to the way in which the raw Diamond has been cut into its final form before it is set within jewellery. The way in which the Diamond is cut determines the Diamonds brilliance, this means that the Diamond should be cut following certain proportions, ensuring that the light reflects against the stone giving off just the max amount of brightness and sparkle. Certain well known Diamond cuts are:

Carat

The carat refers to the weight and size of the Diamond. The higher the carat weight, the larger the stone. A ‘carat’ is defined as 200 milligrams. Each carat is divided into 100 ‘points’ and quite often a carat weight can be referred to as 0.50ct, as an example, or 50 points. Larger diamonds tend to be more desirable, however the other 4C’s will all need to be taken into consideration to establish the diamonds value.

Colour

A diamond’s colour grade actually refers to the lack of colour. In other words, diamond’s that are white, containing little or no colour, receive higher quality grades than those with visible colour.

Clarity

The clarity measures the amount of inclusions there are in the stone. Inclusions are blemishes which can alter the overall look of the Diamond. Most of these blemishes can’t be seen with the naked eye and grades run from ‘Flawless,’ with virtually no imperfections, to ‘Included,’ which contain a significant number of blemishes or imperfections. Below is an internationally recognised scale from the GIA.

 

Buying a Diamond

With all of the above understood, we must appreciate that the price of a Diamond set piece is dependent on the quality of the stone(s). All of the above factors determine how the Diamond would be graded, giving you a final price to consider. Our Diamonds are pre-selected for exceptional quality, the cut, colour and clarity of our stones are evaluated based on a standardised grading scale much like, or equal to the GIA grading system. You may wish to start with a budget in mind and review what is available to you in this price range. From there, you may need to consider compromises; for example, opting for a larger carat weight over clarity to get an item within your budget, and also appreciate what factors are of most importance to you.

Once price is established, style and occasion of the piece needs to be decided upon. You most likely will have some idea in mind of this; for example, shopping for an engagement ring or a classic pair of Diamond stud earrings for everyday wear. We can help with every step of the way including inspiration of styles. We offer consultations to try on items in store and cover every aspect of narrowing down your choices to find the perfect item to go home with.
