The 4 Cs

The 4 Cs: Cut, Colour, Clarity, Carat
Weight and Confidence

The 4 Cs At A Glance

Every diamond is as unique as a snowflake and it’s the cut, colour, clarity and carat that helps define every stone’s true quality. We believe that you can either choose a diamond or you can fall in love with it, and that’s exactly how we select the diamonds that become part of our engagement ring collections.

All of our diamond solitaire engagement rings are a minimum colour G and Si1 clarity, meaning that your diamond will be bright, clear and dazzling whatever carat size you choose.

Discover the four Cs

1. Cut

To release its inner beauty, a diamond must be cut in perfect proportions. A beautifully cut diamond will have lots of sparkle.

2. Colour

A diamond’s rarity and purity is measured by its lack of colour. A pure stone will have a bright, white appearance.

3. Clarity

Most diamonds have inclusions. We select the best to ensure these unique markings will not be visible to the naked eye

4. Carat

Often confused as the size of a diamond, the carat is actually the measure of a diamond’s weight.

Our 5th C: Confidence

We don’t just tick off the 4 Cs or adhere to a technical checklist. For us it’s about genuine passion and care and about making sure your engagement ring sparkles.


"Choosing your engagement ring is the most important jewellery purchase that you'll make in your whole life. Our job is making sure that those diamond rings are perfect."

Precious Metals

Choosing The Best Metal For Your Engagement Ring

The type of metal you choose can have a big impact on both the look and price of your engagement ring. Metals with white tones such as platinum and white gold can look modern and contemporary whilst yellow gold can be more traditional. Rose gold is also becoming a very sought-after metal and can create a beautiful, vintage style.

  • Platinum


    The rarest of all precious metals, platinum is by far the most luxurious choice. Its natural white colour will not tarnish or fade and, although it can be scratched, none of the metal will be lost over time. Platinum is the most secure setting for your diamond and looks beautiful in both contemporary and vintage styles.

  • White Gold

    White Gold

    White gold is created by mixing yellow gold with white metal alloys such as silver or platinum. Its natural colour has a champagne appearance and so is coated with rhodium, a member of the platinum family, to give it a bright, white finish. White gold is modern and contemporary and will show off your diamonds brilliantly. One consideration to bear in mind is that you will have to have your engagement ring re-rhodium coated periodically to retain its bright white lustre.

  • Yellow Gold

    Yellow Gold

    One of the most precious metals, gold has long been a symbol of love, success and luxury. A beautiful golden colour which does not rust, tarnish or corrode, gold is highly reflective and strong which makes it a perfect setting for a diamond. We normally use white gold settings on our yellow gold engagement rings to ensure that the yellow colour of the gold band is not reflected in your diamond.

  • Rose Gold

    Rose Gold

    Another alloy of yellow gold, rose gold is created by adding a higher percentage of copper to the pure metal. Creating a beautiful, feminine colour which is perfect for vintage styles, a rose gold engagement ring is perfect for those looking for something a little different.

  • 9ct or 18ct

    9ct or 18ct

    We offer gold, including white, rose and yellow, in both 9ct and 18ct. This refers to the purity of the gold in the ring. All gold is mixed with alloys to make it harder and to increase its durability, pure gold would be far too soft to be used in jewellery. In practical terms, this means that 9ct gold is more affordable but contains less gold, whilst 18ct gold is slightly more expensive but contains more precious metal.
