5 Factors that Guys Need to Know – When Choosing an Engagement Ring in Singapore

  1. Types of Diamonds and Certifications
  2. Diamonds – The 4C’s
  3. Diamonds – The Shapes
  4. Engagement Ring – The Settings
  5. Engagement Ring – The Ring

1. Types of Diamonds and Certifications


Buying a Diamond Ring or otherwise known as an engagement ring, is usually a significant first investment towards the marriage journey in Singapore. Therefore, we know that you need to be assured that the Diamond is authentic as well as look the part. Traditionally, diamonds are mined — ‘natural’ diamonds formed from carbon subjected to extreme heat and pressure underneath the earth’s crust over many years. With commodification of diamonds over the years, you will expect that supply dwindles and demand for it grows, which definitely led to a supervised pricing around natural diamonds. This brings about a new trend of lab grown diamonds, which are created and grown in controlled environments but are chemically and physically identical to mined diamonds.

As compared to mined diamonds, grown diamonds are formed over a short few weeks, and the main difference is just the origin of the diamond, and the fact that grown diamonds do not further contribute to the ecological and ethical impact brought about by mined diamonds! But, to consumers like yourself looking out for that engagement ring, grown diamonds are definitely more affordable than mined diamonds, while having the same types of certifications from internationally renowned gem labs like GIA (Gemological Institute of America) and IGI (International Gemological Institute).

So, take note of the type of diamonds that are presented to you and you will then know why there is a difference in pricing between the both. However, always make sure that either diamonds offered are graded and certified.


2. Diamonds – The 4C’s


Now, after knowing whether to choose a more affordable yet similar lab grown diamond, or the traditional mined diamond, you will usually find yourself looking at some terms that are very close-to-heart for the average Singaporeans. The 4C’s for Diamonds (not the 5Cs for choosing the perfect husband, we’re talking about engagement rings here!), gives you an idea of the quality grading of a diamond, and that is synonymous with the cost of it. The 4C’s are namely, Carat, Cut, Colour, Clarity. To make it easier for most guys out there, let’s start with the easiest C, Carat.


a. Carat

Carat size, or Carat weight, is the notable unit of the size of the diamond rings, and commonly used as the first point of comparison when finding out the price of a diamond. The larger the carat weight, the harder it is to find/create and therefore the more expensive it is. At Authica J, the typical engagement ring price with a 0.75 Carat Diamond starts from SGD 1,818, while one with as 1.0 Carat Diamond starts from SGD 3,938. This gives you a better idea of how the cost of a diamond scales with the Carat.

Of course, we all know that size does not matter as much, as we move on to the next 3 C’s that contribute to how aesthetically pleasing a diamond looks.


b. Cut

The Cut of a diamond ring is determined by how a diamond’s facet interface with light. It determines the overall ‘beauty’ of the diamond, and that is why it is one of the most important factors of choosing a diamond. If a 1 Carat Diamond is cut poorly, it will still appear dull even with a higher colour or clarity grade (which we’ll talk more about later). This may be confused with the ‘Shape’ of a diamond, but just note that it is the rating for how well a diamond interacts with light

Quality of a Diamond Cut is determined by:

  • Precision of the Cut
  • Polish
  • Symmetry
  • Brilliance
  • Scintillation

Cut are graded according to scales that differs across the many diamond ateliers; Authica J follows the GIA’s cut scale, with the highest being ‘Excellent’, and lowest being ‘Poor.

c. Colour

Apart from seeing how a diamond ‘sparkles’ under light, Colour will be the second most important detail for you when choosing a diamond. The ‘less’ colour a diamond has, the higher perceived value it has. Check out the following colour scale:

Most ateliers will recommend going for a ‘colourless’ or ‘near colourless’ grading, but we recommend that you have a look at the diamonds in person, and see if the difference in colour is distinguishable to you. For example, most people won’t be able to tell apart the highest grade ‘D’ against a grade ‘E’, so it is really up to you and your budget on which Colour rating to choose.


d. Clarity

Last but not least, Clarity, a measure of the purity of the diamond, or conversely the absence of ‘inclusions’ and ‘blemishes’. These ‘inclusions’ are tiny black spots that you can spot from certain angle when looking at the diamond, and they do come with a grading scale as well:

Flawless grading diamonds, have no visible ‘inclusions’ or blemishes’, while grades such as VVS1 or VVS2 have ‘inclusions’ so slight that they are even difficult for a skilled graded to spot under 10x magnification. Again, it is best that you view this in person to see if the presented diamond for your engagement ring to know which grading to go for.


3. Diamonds – The Shapes


For most engagement rings, the ‘Round’ shape is one of the most sought after shape for its timelessness, but also one of the most expensive due to a lower yield per raw stone as compared to other shapes. You can definitely explore some other diamond shapes, matching it with the settings and ring to create your very own engagement ring. Here are some of the shapes of diamonds:

List of common diamond shapes

  • Round
  • Square
  • Rectangle
  • Octagonal
  • Oval
  • Pear
  • Heart
  • Marquise
  • Triangle
  • Tear

The shapes of the diamond may not make much sense on its own, and hence it is very much dependent on the ring type and setting you choose for the diamond shape. Experienced diamond ateliers will be able to recommend certain settings to better pronounce the shape of the diamond, and suggest suitable pave diamonds to match the diamond shape and setting.


4. Engagement Ring – The Setting


Choosing the Setting for your engagement ring refers to how the diamonds are set, or placed on a metal band/ring. The ring setting defines the ring’s style, while also highlighting the beauty or cut of the engagement diamond. Depending on the setting, the ring can be seen to take either a modern or traditional form, and it is imperative that you understand what setting to go for to best suit your tastes. Here’s a quick overview of the common settings available:

I know, there are already so many options to choose from, and you can surely rely on your diamond atelier to recommend you suitable settings for your selected diamond shape. Here are some of the most classic and chosen settings for your reference too:

  • Solitaire
  • Prong
  • Trellis
  • Cathedral

Again, different providers may have their own naming conventions for the settings, also make sure that you’re able to see a simulation of how your engagement ring will look like with the diamond shape and ring setting!


5. Engagement Ring – The Ring


Last but not least, the ring, or otherwise known as the ‘metal’, that you choose to complement your ring is important as it should match the nature of ‘colourless’ of your diamond. It is generally recommended to choose white gold variants for colourless diamonds, and gold for slightly coloured diamonds:

After matching the colour of the ring to the diamond, you should know the next important point of choosing a type of metal over another. For example, White Gold, is easier for jewellers to work with (since it’s soft metal), and easier to maintain and polish it over time to revert the ring’s original luster. Comparing this with Platinum, which is a durable metal and will last a longer time than metal, which is harder to work with and hence increasing the potential price of the engagement ring. These are some considerations for the final piece to decide for your engagement ring.
