Diamond Search

To start your search consider the available diamond shapes when considering your perfect ring.

The first decision in your search for the perfect engagement ring is the shape of your centre diamond. The classic engagement ring features a Round Brilliant Cut diamond, although Oval and Pear-shape diamonds are also very popular at the moment. There is no right or wrong, simply personal preference, and all shapes are equally suitable as engagement rings. Of course, the decision is best made by the ring’s recipient, so do your best to find the diamond shape your partner prefers.


Related to diamond shape is ring style. Starting with options of yellow or white gold or platinum, you will also need to consider: solitaire, halo, double halo, cluster, trilogy…vintage or contemporary… and so on. We highly recommend you do your homework on this point so that the style you choose matches your partner’s preference.

With shape and style confirmed, selecting an actual diamond is the next step. The following four characteristics are used as the basic reference points for assessing a diamond’s quality, and therefore its value:


We’ll start with the easy one – carats. Carats are a unit of weight measurement (not size) for a diamond. Of course, the bigger the diamond the more expensive (assuming all other criteria are identical). Fun fact: the word ‘carat’ derives from carob tree seeds which were originally used as an agreed measure of weight in early diamond trading.


How well a diamond is cut has a big impact on how well it reflects light and sparkles. We highly recommend excellent cut as being the most important criteria in selecting your diamond, especially if it is a Round Brilliant Cut.


Clarity basically refers to the presence of inclusions in your diamond. Certified stones are rated from ‘Internally Flawless’ to ‘Included’ (with multiple sub-ratings along the way). An important distinction from a diamond’s appearance is whether it is ‘eye clean’, meaning whether its inclusions are visible to the naked eye. Diamonds that are graded in the Slightly Included 1 (SI1) and Slightly Included 2 (SI2) range are typically on the cusp of being eye clean, with most SI1s being eye clean and most SI2s having some visible inclusions. Van Bercken sells on ‘eye clean’ stones, above SI1 and all of our diamonds are GIA certified.


A diamond’s colour grade refers to its lack of colour. The more colourless the diamond, the higher quality grade it will receive. Colour grading commences at ‘D’ and goes all the way through to Z. D, E and F-colour diamonds fit within the ‘colourless’ range. They are rare and more valuable than similar diamonds of lower colour grade. We do not sell diamonds below ‘G’ colour as graded by GIA.
