Engagement Ring & Diamond Guide

Choosing the right engagement ring. A guide for men...

Deciding whether to choose a ring yourself, or to choose it with your partner, is a personal choice that will be influenced by how confident you are in choosing the perfect ring for her.

Ideally you will already have an idea about her personal tastes and preferences. If you’re unsure, take a look in her jewellery box to discover what style she likes and take note of metals (9ct or 18ct), gold colours (rose, yellow or white), designs (plain and simple, lots of filigrees and detailing, moder nand contemporary, bold or understated) and gemstones (purple amethysts, pearls, rubies, etc). This should give you a good idea of what she is most likely to prefer.

Don’t forget: Clogau offers a 14-day money-back returns policy so that you can return the ring if she doesn’t like it.

You may decide that you would prefer to shop for a ring after the proposal, together, so that your partner can be involved in the experience and there’s no danger of choosing the wrong ring. This option can be just as romantic with the use of a prop to propose with such as the Tiara Milestone bead charmFrog Prince bead charm, or Lovespoon bead charm, which are perfect substitutes.

For something extra special, you could propose with a Cariad locket or Key Notes pendant with the message "Will you marry me?" written on a note inside.

How much should you spend?

As a guide, it’s generally recommended that you spend between 1-3 months salary on an engagement ring. Our advice is to spend what you feel is right, with regards to getting the desired quality. Don’t forget though, this will be a once-in-a-lifetime ring.

What ring size is she?

There are a few ways that you can find out her ring size without having to ask her. The easiest way would be to borrow a ring of hers while she’s away and compare it with our online ring size guide, or take it to a reputable jeweller for them to measure. You could also ask a close friend or relative to find out for you, as long as you can trust them with your secret.

Diamond Guide

To be able to choose the most perfect engagement ring, you need to know a little about diamonds. There are four key areas to focus on so that you can then decide which are most important to you and how they each affect the price of a diamond.


You should first decide which shaped diamond she would prefer. There any many options, with the two most popular shapes being princess (square) and round. Undoubtedly the most important factor to consider is the cut as this determines the diamond’s ‘sparkle’ and has the most impact on its overall beauty. Our diamonds are available in the classic round brilliant cut, perfected to generate maximum radiance and the princess cut, a contemporary square cut that has become very popular this millennium.


A diamond’s colour is measured by how colourless it is. Diamonds are graded from D (colourless and extremely rare) to Z (noticeably coloured). Clogau Compose diamonds are near colourless and of superb quality. We have carefully selected three choices for you to choose from – J, I and H (H being the best quality diamonds that we make available for you to choose from).


The weight of a diamond is measured in carats and points; 100 points = 1 carat. The carat refers to the diamond weight and is a rough reflection of the overall size of the diamond (but not the quality of the diamond). The ideal carat weight for an engagement ring will depend on the size of the wearers finger and your budget.


Almost every diamond that exists contains naturally occurring imperfections, most of these are very tiny and cannot be seen with the naked eye – only with x10 magnification. They have no visible impact on a diamond’s overall appearance. Diamonds are graded from FL (flawless) to I3 (not recommended). When you start composing your ring you can choose from SI1 (slightly included), VS2 (very slightly included) and VS1 (very slightly included, our best) diamonds.

Good luck! If you need any further advice, please don’t hesitate to contact our sales office on 0845 606 88 77 who will be more than happy to advise you further.
