If you've been plucking up the courage to pop the question, you'll have been on the lookout for the perfect diamond engagement ring to seal the moment. Yet this part of the process can be daunting, and you'll want to make the perfect impression at such an important part of your life. So, how do you go about shopping for that ultimate ring?

Cost

The first thing to be aware of is the cost disparity. These rings can run the gamut in terms of price, so you will need to set your own budget before you can start looking for options. This can be one of the toughest decisions for many, but only you can make that conclusion based on your individual circumstances.

Cut

Perhaps the most important element of a diamond is its cut. This refers to how symmetrical it is, often evaluated on the basis of proportion, thickness, light quality and finish. You can take advantage of a grading system that certainly helps anyone with an untrained eye and should ask your retailer for their advice.

Clarity

There's another scale when it comes to clarity. Here, professionals use high-powered magnifying tools to evaluate any particular stone, and those that have imperfections, chips or cracks will not score as highly. Many diamonds contain mineral deposits in their natural state, and this can often lead to blemishes, which are sometimes referred to as "flaws" by experts.

Colour

Natural diamonds often have a slight tint to them, affecting both the way that they look and their value. If you want to opt for a colourless diamond, these are graded according to the slightest trace of colour. Where a diamond is sold as coloured, they are graded on saturation and hue.

Carat

One other factor to consider is the weight of the diamond, measured in milligrams or "carats." Essentially, the larger the diamond, the more expensive it will be, but this is only one part of the picture and you need to consider clarity, cut and colour as well.

What to Do Next

It's very hard for anyone who is not an expert to understand the value of a diamond, and it's important to work with an expert in the field if you're not sure. They'll help you choose the right diamond according to the various grading charts so that you can build your engagement ring and get ready for that momentous occasion.
