What Is a Carat?

With diamonds, the carat refers to the weight of a diamond. A one-carat diamond is 200mg meaning a 5-carat diamond weighs 1 gram. The graph below displays the diamond weight-to-carat ratio.

1/2 carat 0.1 carat 0.1 gram
1 carat 0.2 carat 0.2 gram
2 carats 0.4 carat 0.4 grams
3 carats 0.6 carat 0.6 grams
4 carats 0.8 carat 0.8 grams
5 carats 1 carat 1 gram

The most popular diamond carat that people usually go for is 1 carat, as it is chic and timeless.

The 3-Month Salary Rule

The 3-month salary rule is the guide to the amount that you should spend on an engagement ring. This is the traditional option. To work it out, calculate 3 months of your annual salary, this indicates how much you should spend.

It is your personal preference whether you decide to follow this rule or not. You may choose to spend more or less on an engagement ring, it’s all a matter of personal choice!

How Much Does a Carat Cost?

The cost of a diamond ring depends on several factors, including the 4 C’s, such as carat cut, colour, and clarity. Additionally, the metal of the band. But what is the average cost per carat? Below you can find a table that shows the carat size and average cost in the UK.

Another factor that may affect the cost is the brand of the engagement ring.

What Are The 4Cs of a Diamond?

  • Cut- The cut refers to the shape of the diamond. Princess cut, Oval cut, cushion cut, round brilliant cut, and pear cut are a selection of traditional options. An excellent cut can also depend on how well the diamonds shine.
  • Clarity- is based on the visibility of internal inclusions and blemishes. The grade of clarity will determine how flawless a diamond is.
  • Carat - The weight of the diamond
  • Colour- The colour of every individual diamond will be graded on a scale. On the colour scale a colourless diamond begins at D. Moving up the scale means the diamond ranges from near colourless up to a light yellow tint. . .


Characteristics of a Diamond

Below is how you can identify the quality of a diamond from its cut, colour and clarity.

The colour of a diamond is graded in letters, from D-Z. The higher up in the alphabet the more clearer your diamond is. Let's break it down:

Grade Colour
D-F Colourless
G-J Almost Colourless
K-M Faint Yellow
M-R Very Light Yellow
S-Z Light Yellow

The colour of the diamond affects the value. Choosing the right colour is a matter of personal preference.

The cut of a diamond affects the way that the diamond appears and how well it sparkles.

Cut Quality
Excellent Returns light making the diamond appear sparkling and has a high level of brilliance.
Very Good High-quality cut with minor and almost unnoticeable imperfections.
Good Reflects light well but not as well as an excellent cut.
Fair Light escapes from the bottom or sides, reducing brilliance.
Poor A poor cut doesn't reflect light or sparkle.

A well-cut diamond will sparkle more in the light.

The clarity of a diamond impacts the way the diamond appears.

Clarity Definition
F The diamond is flawless and has no blemishes under a 10x magnification.
IF There are no internal flaws, but external flaws are visible only under 10x magnification.
VVS1 There are slight blemishes, but they are difficult to see even under 10x magnification.
VS1 Minor blemishes visible under 10x magnification.
SI1 Noticeable blemishes and inclusions that can be viewed under 10x magnification.
I1 Blemishes that are visible to the naked eye.

Diamonds with unnoticeable blemishes are valued higher than diamonds that have visible blemishes. This is because they are seen as higher-quality diamonds.

Does It Matter?

Carats costs and tradition, does it matter? In short, no. Engagement rings are a symbol of love, the diamond engagement ring represents your unity.

Besides, the size and cut of your engagement ring should be chosen based on several features. Let's take a further look into the considerations you should make when choosing an engagement ring…

Personal Style

Whether you are shopping for an engagement ring with your significant other or you are leaving the proposal to be a total surprise, finding the perfect ring is key when it comes to getting down on one knee.

Does it match their style? They will be wearing this ring for a lifetime so it's important the ring reflects who they are and matches their preferences.

Finger Size

How does the diamond ring look on the finger? Small fingers can be overwhelmed by large diamonds whereas larger fingers can make the diamond appear smaller. It is important to try on a few different cuts and carat weights to determine which style and size diamond suits you best.

Budget

Consider your budget and how much you are willing to pay for an engagement ring. You must set a budget and stick to it. Before making a purchase, carry out some research and shop around to find the best value for your budget.

If you are looking for a larger diamond but don't have the budget, laboratory-grown diamonds can be a great alternative to natural diamonds, holding the same quality for a lower price.

Laboratory-Grown Diamond Rings

In recent years, laboratory-grown diamonds have become increasingly popular. Laboratory diamonds are created in specialised environments and can be created by two processes, High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD). Both of these processes start with what is called a diamond seed.

The diamond seed is placed into the environment and within 6 weeks a diamond is formed. Laboratory-grown diamonds are real diamonds and the only thing that differentiates them from natural diamonds is the way that they are formed.

With laboratory-grown diamonds, you can get a higher quality diamond and a larger size diamond for your budget.
