Find out what your girlfriend likes
Look at their existing pieces of jewellery, particularly her favourite ones. What colour jewellery does she prefer? Remember most girls will already have a very definite idea of what style engagement ring they would like (scarily some from the age of 13!)

Find a good Jeweller
You need to find a Jeweller you feel comfortable with. They should be members of The National Association of Goldsmiths. Some stores that look like actual Jewellers are only Jewellery Galleries and will not have the same experience, knowledge or qualifications of real Jewellers.

Decide on your budget
Before you start looking at rings, have a clear idea of what your budget is and what her expectations are. This will help your jeweller help you.

What Rock?
Diamonds are a safe bet! It's traditional and it matches everything. Unless you know that your girlfriend has a deep dislike for them, or alternatively has an absolute love for another stone, then you can't really go wrong with a diamond.

The 4 C's - There are four variables, commonly known as the 4 C's, which will affect its price.

Carat – this is the unit measurement for a diamond. Each carat is made up of 100 points. However, do remember it is a measurement of weight and not the size. A diamond is a 3D thing – a one carat diamond ring does not look twice the size of a 50 point diamond when viewed from above. It is always handy to ask what the size is in millimetres; it will help you to compare different stones.

Colour – most customers want the whitest diamond they can afford. The colour is measured from D (colourless) down through the alphabet as the stone becomes more coloured. (The scale starts at D, because we cannot rule out the chance of finding even purer colours in the future). D and E are very rare and expensive; at Lance James our standard colour range is from F to H. Others use lesser stones.

Clarity – this is basically how clear a diamond is. Because it is a natural product, it will have natural imperfections (“inclusions”). The fewer inclusions, the more light is reflected from the stone resulting in more sparkle. The scale used to measure clarity is as follows:

F Flawless – no internal or external inclusions.

IF Internally flawless – only external inclusions.

VVS1 - VVS2 Very, very slightly included.

VS1 - VS2 Very slightly included.

SI1 - SI2 Slightly included, but still not visible to the naked eye.

I1 - I3 Included.

Stones that are VVS2 to F are very rare and very expensive. And their inclusions can only be seen with the help of magnification. Most couples will opt for something between SI1 and VS1.

Cut – often forgotten, this variable is as important as the clarity and colour. The proportions of the cut are incredibly important; when the light enters the stone, if the angles of the cut are not correct, this will reduce the amount of light which is reflected back out - therefore reducing its sparkle.

The various different shapes of cut will also affect the sparkle. The most effective shape is the brilliant or round cut.

Don't worry about being blinded by science – it's not critical but it is handy to be aware of what factors will affect the price of your diamond engagement ring. If the diamonds you are looking at all seem too pricey for your budget – then consider reducing the size rather than the quality.

We all know that size does matter – but so does quality!

Certificates
Although more and more people are asking for certificates, they are not essential, and you will be paying extra for this paperwork! Spend this money on a bigger stone.

A certificate just tells you what grade your diamond is; even bad diamonds can get a certificate. It is not a guarantee of quality.

Choose a setting
Contemporary or classic, platinum or gold, the choice is yours. We have a vast range of ring designs to cater for the most discerning customers; over 8,000 at the last count. Bespoke means the choice of design is endless - see below.

Bespoke rings made to your designs
For those customers who have a more original design in mind, we offer a complete commission service. With the aid of our on-site workshop and advice from our experienced jewellers, you can work with our staff to achieve a design unique to you. A drawing, however sketchy, can be enormously helpful in conveying your idea accurately to the jeweller.

As it is unique to your taste we cannot accept exchanges on bespoke commissions.

What happens if she doesn't like the ring?
At Lance James, if you want to keep it a surprise, you can buy a ring and exchange it if it's not exactly what she wanted.

If you want to make it a surprise, let us know your intentions and don't try to commission an original bespoke design.

If you choose one from our extensive range in the shop and the ring is not the style that she was hoping for, we can then either exchange it, or make you a ring to order.
