how to choose a diamond

Choosing a diamond may seem like a daunting process, but it is one of the most exciting
aspects of designing an engagement ring.

At Beaudell we source diamonds and gemstones according to your unique specifications. As the focal point of an engagement ring, we need to take into consideration the clarity, colour, cut, and shape of the diamond as this will affect the price point. It is a good idea to have a budget in mind before asking for diamond sourcing as we will then be able to get the best quality for your money.

Please kindly schedule a diamond viewing appointment by filling in this form should you wish for us to source the diamond on your behalf.


diamond shape

When choosing your diamond, besides the carat weight, the shape is the most crucial factor of the final design and overall look of the ring. However, this does not form part of the 4C’s. The shape and the cut of the diamond are often confused. The cut instead refers to the proportions and facets of the diamond.

Below are the most common shapes. Each of these has variations of how its cut, for example, a round diamond can have different cuts such as the Brilliant cut which is the most common cut, but the Rose cut, also referred to the old mine cut, is one of the first types used when diamonds first was used in jewellery.


The clarity of the diamond refers to the comparative absence of inclusions and blemishes. Clarity grades are based on the number, size, relief and position of inclusions and blemishes that can be seen under 10x magnification. Inclusions and blemishes are the natural results of a diamond’s formation deep within the earth under extreme heat and pressure. Diamonds without these “fingerprints” are rare, and rarity affects a diamond’s value.



Often the cut and the shape are used interchangeably, but the cut instead refers to the proportion and number of facets of the diamond instead of the shape. The cut quality is the factor that fuels a diamond’s fire, sparkle and brilliance. The allure and beauty of a particular diamond depend more on cut quality than anything else.


The colour grade of the diamond is all about what you can’t see. The closer the diamond comes to colourless the more it increases in value. This grading is not taking into consideration the fancy coloured diamonds with hues of pinks and blues, even fancy yellows which will lie outside the standard colour range.


The metric “Carat”, which is defined as 200 milligrams, is used to measure how much the diamond weighs. All else being equal, a diamonds price increases with its carat weight, because larger diamonds are more rare and desirable. However, two diamonds of equal carat weight can have very different values (and prices) depending on the three other factors of the 4Cs: Color, clarity and cut.
