How To Choose A Diamond

How To Choose A Diamond

When women dream about their ideal engagement ring, they are usually picturing ring settings - solitaire, trilogy or halo, in a certain type of metal. When it comes to the diamond itself, most people know they want a big, high-quality diamond but aren’t confident on the specifics. Here’s your introduction to all you need to know.

Select A Shape

Round Diamonds

When choosing a diamond, the first step is usually selecting a shape. The round shape is the most popular with over 75% of engagement rings featuring a round centre stone. It was the first modern diamond shape and has maintained its popularity due to its unparalleled brilliance, fire and scintillation.

Select A Shape

Fancy Shapes

All non-round diamonds are classified as ‘fancy shapes’. Cushion diamonds can be square or rectangular in shape with curved corners and soft, vintage facet patterns. This antique style has emerged as a popular choice again in recent times. Princess diamonds have a square shape with sharp angles producing excellent light performance. Princess diamonds are prized for their modern, clean lines and stunning sparkle. Emerald and asscher diamonds feature a rectangular and square outline respectively, with cropped corners. They have fewer facets than other shapes, emitting a subtle and sophisticated beauty with greater emphasis on clarity rather than sparkle.

Choose a Size

While carats can give a good indication of size, diamonds of the same weight will have some variation in size. If having the biggest diamond possible is important to you, consider measurements as well as carats.

Carat

Carat

Despite popular belief, although a diamond carat can give a rough indication of size, it is predominantly an indicator of a diamond’s weight. The value of a diamond increases exponentially based on weight and size, so all things being equal, a 2 carat diamond ring would be worth more than two 1 carat diamond rings. Whether you are looking for a 1.5 carat diamond ring, a 3 carat diamond ring or a 5 carat diamond ring, don’t forget to pay attention to the other 3 C’s when choosing your diamond: cut, colour and clarity.

Cut

Cut

Like us, each diamond is unique, and that includes their cut. Although many confuse cut with shape, cut refers to the quality of a jeweller’s work in creating facets, light refraction, symmetry and overall shine in a stone. If a diamond is cut poorly, it may look slightly rough, uneven or asymmetrical and, more importantly, won’t reflect as much light or be as valuable as a skillfully cut diamond. There are many types of diamond cuts. Some will naturally create more sparkle, like a brilliant round or princess cut, while others are cut in longer, stepped planes, to showcase the stunning clarity of the diamond, like an emerald cut. To find the best diamond cut, narrow our filter to ‘super ideal’ and adjust the price to suit your budget. For further guidance, refer to our diamond cut chart in the link below. Make sure you consider more than just the cut: the higher the clarity, colour and carat, the more valuable the diamond will be.

Colour

Colour

As a diamond forms, traces of nitrogen often get caught inside and cause a slight brown or yellow tinge, affecting its colour. Assuming every other diamond quality indicator is equal, a stone with less colour is more highly valued than one with more colour. At Diamond Exchange, we only carry diamonds within the highest colour grades. Diamond colour selection depends on the setting, and if you are shopping for a rose gold or yellow gold ring, you can choose a stone slightly lower on the diamond colour chart without it being noticeable, because the colour of the metal makes the diamond appear less coloured.

We recommend choosing a diamond of the highest colour you can afford without sacrificing cut, carat or clarity.

Clarity

Clarity

Each diamond varies in clarity, ranging on a scale from flawless to included, and no two are identical. A diamond’s value and rarity is based on the number of inclusions (internal flaws) - the fewer inclusions, the higher the value. If you are unsure about which diamond clarity to choose, refer to our diamond clarity scale in the link below or a diamond clarity chart. While important, diamond clarity is just one of the Four C’s, so be sure to consider all four before you purchase.
