Engagement Ring Guide

An engagement ring can be absolutely any ring of your choice. It has become very fashionable to pop the question to the love of your life with a birthstone or a combination of gemstones. However, the traditional engagement ring consists of only two elements: gold and diamond.

When selecting an engagement ring there are many requirements to consider. It is important to understand the purity of the gold used in the ring as this will affect the strength and colour of the gold. At QP Jewellers we use 9ct gold in the majority of our engagement rings. We believe this to be a fantastic balance between durability and beauty.

How much should I spend?

Traditionally it is said that two months' wages should be spent on an engagement ring. In truth, it doesn't matter how much you spend as long as you are confident in the quality, design and value for money that the item has to offer.

At QP Jewellers we do not have the associated overheads of running a high street outlet which means we can reflect this in our prices to you. We offer fine, high quality diamond engagement rings at a fraction of the normal retail cost. And combined with our fast, free FedEx Express delivery service, we're sure you'll find the right ring for that big day.

Selecting the right diamond

We offer more than 70 unique designs of round cut diamond rings to suite every budget. Our round cut diamonds are of colours G to M and we offer diamond clarities of I-3 to SI-1. For more information on diamond clarity and other characteristics please see Diamond Education.

When selecting a diamond ring you should consider the four Cs: Cut, Colour, Clarity and Carat Weight. By finding a good balance between these characteristics you can make an informed decision on which diamonds to choose.

Cut (shape)

The brilliance of a diamond is dependent on the cut. Quality diamonds must be professionally cut, and not spread. "Spreading" is an improper practice which compromises the proper proportions of the diamond to make it increase in weight. A classic round, brilliant cut diamond has 58 facets: 33 on the top, 24 on the bottom, and the culet, which is 1 point at the bottom. Every one of these facets has to be placed in exact geometric relation to the next when the stone is being cut.


When viewed under a jeweller's loupe, most diamonds contain slight traces of light brown or yellow pigment. Colourless and near colourless diamonds are much more valuable, and taking the stone's size into consideration, a single increase in colour grade can raise the value of a diamond by thousands of pounds (or dollars) per carat. Engagement rings traditionally use diamonds that are colourless, or near colourless.

Diamonds can be naturally found in shades of blue, green, red, pink and deep yellow. These are known as fancy diamonds. Worldwide, colourless diamonds are graded using an alphabetical scale. Colourless or rare white diamonds are graded D, E and F - the most valuable being the D grade, which is extremely rare.


The clarity of the diamond depends on the number, size and location of inclusions found in the stone. Under the magnification of a jeweller's loupe, imperfections or trace minerals can be seen in the stone. These are called inclusions. The diamond will increase in value when there are fewer inclusions present, and will be clearer and more brilliant. A diamond with no inclusions is extremely rare and valuable, and is given the term flawless.

Carat Weight

Judging a diamond on the carat weight alone can be very misleading. The cut, clarity and colour of the diamond are extremely important and have to be taken into account. A large stone will not generally be valuable if it lacks purity, high grade colour and brilliance. However, as larger stones are rarer than smaller ones, the value will rise exponentially with carat weight, making a 3.0 carat diamond worth more than three 1.0 carat diamonds of equal quality.

So, when making your decision as to which diamond to buy, it is important to take all the above factors into account. Remember the four Cs: Cut, Colour, Clarity and Carat Weight.
