Where do you start? What do you prioritise? How do you skip past the jargon? Well, we created this guide because that diamond you're looking for does exist and hopefully, we can take you there.

From the 4Cs right down to what's the best setting, start asking yourself the right questions before you buy diamonds online!

The first question is budget.

What's My Budget?

How do I budget for an engagement ring?

Determining a budget for your desired gemstone, ring or diamond is pivotal because it gives you a ceiling for what you can and cannot buy.

It's imperative that you stick to your budget because, as you research more into engagement rings, you'll start seeing how the prices fluctuate once certain elements are taken into account.

These elements are called the Four Cs and they determine the quality of a diamond or gemstone.

Finding the ideal shape means you'll need to know what other shapes are out there.

Once you have your diamond, it's time to move onto the setting.

They influence how the ring sits and also if it's accompanied by any other diamonds etc. 

Once you have your setting, what metal should it be in?

The arguments regarding gold, white gold, rose gold and platinum are quite fascinating. 

They each have their own pros and cons which range from how comfortable they are to which metal is easier to work with!

What you need to remember is that platinum is the most expensive out of the four. It's renowned for its longevity but it requires special knowledge when working on it e.g. resizing.
