Step-by-Step Buying Guide

Whether you're buying your first diamond or upgrading to something special, understanding the 4Cs will help you make the right choice. Think of the 4Cs as the diamond’s report card — they tell you how it looks, how much it sparkles and why it’s priced a certain way.

Here’s a simple breakdown:

1. Cut – The Bling Factor

The cut of a diamond isn’t about its shape (such as round, oval, or princess) — it's about how well the stone is shaped and polished to maximise its ability to reflect light. A well-cut diamond is designed to interact with light most spectacularly, creating brilliance, fire and scintillation (the flashes of light seen when a diamond moves). A poorly cut diamond can look dull, even if it’s large.

Tip: If sparkle is what you’re after (and who isn’t?), prioritise a higher cut grade. At Limelight Diamonds, most of our pieces are crafted using diamonds with unique cut styles.

2. Colour – The Clearer, the Better

Diamonds come in a range of whites, from colourless to slightly yellow. In diamonds, purity of colour equals perfection. 

• The grading scale runs from D (exceptionally rare, icy white) to Z (warm champagne tones), with value increasing as the stone approaches colourless perfection.

• D-F are considered colourless

• G-J have a slight warmth, often invisible to the naked eye

Tip: For a bright, white look without the premium price, G or H grades are a popular sweet spot.

3. Clarity – The Inner Beauty Check

Diamonds naturally form with tiny marks inside (inclusions) or on the surface (blemishes). Clarity measures how many and how visible these are.

• Common grades include FL (flawless), VVS (very very slight inclusions), VS (very slight), and SI (slightly included)

• Most inclusions are microscopic. As a result, they don’t affect the visual appeal.

Tip: VS or SI1 clarity is often a smart choice — it looks flawless to the eye but costs less than higher grades.

4. Carat – More Than Just Size

Carat measures the weight of a diamond, not its size, although they are often linked. One carat is equivalent to 200 milligrams, but a diamond's size can vary depending on its shape and cut. A well-cut diamond of one carat might look larger than a poorly cut one, even if they weigh the same.

Tip: Slightly under full-carat weights (like 0.90ct instead of 1.00ct) can offer great value with no noticeable size difference.

Lab grown diamonds give you more flexibility with the 4Cs. Since they’re more affordable, you don’t have to compromise — you can often get a larger, cleaner, or brighter diamond for the same budget compared to a mined one.

Choosing the Right Certification

A diamond’s beauty might be in the eye of the beholder, but its authenticity lies in certification. For complete peace of mind, your lab diamond should come with certification from respected gemological laboratories like IGI or GIA — the global standard-setters in diamond grading.

Limelight Diamonds offers only SGL, IGI and GIA certified diamonds, ensuring that you receive exactly what’s promised — with full transparency on grade, origin, and quality.

Selecting the Perfect Jewellery Setting

Once you’ve chosen your diamond, the next step is to find the setting that enhances it. Whether it’s a classic solitaire ring, a chic pendant, or an intricate bracelet — the right setting can transform a beautiful gem into a breathtaking statement.
