How to Choose the Right Diamond For Your Ring

Diamonds come in an extraordinary range of varieties when it comes to using them as a setting for a ring. You can select a diamond based on budget, colour, quality, carat and shape. At many jewellery stores, you can find a ring with a diamond that suits your preferences or opt to have a piece tailor made to suit your exact specifications.

The 4 C’s

Diamonds are graded according to the 4 C’s – clarity, colour, cut and carat weight. The 4 C’s are used to value and categorise diamonds according to their rarity, allowing you to select one that suits your budget and intended use.

  • Clarity – Based on the number, size, position and type of inclusion visible under 10x magnification. Grading ranges from LC (loupe clear and flawless) to VVS1-2 (very slightly included), SI1-2 (slightly included) and P1-2 (visibly included).
  • Colour – Generally used for grading white diamonds, this measures the purity ranging from D (colourless and the most valuable) to Z (dark yellow, brown or gray and least expensive).
  • Cut – The way a diamond is cut affects its brilliance, scintillation and fire. There are many shapes available such as emerald, cushion and marquise cuts but the most popular is the round brilliant cut.
  • Carat – The unit measurement for the weight of the diamond and its size. 1 carat is equivalent to 0.20 grams.

Keep in mind that even visibly included diamonds with tinges of colour are incredibly beautiful and have useful functions. For example, diamonds with lower clarity are great when arranging a row of smaller diamonds in a ring design whereas high clarity diamond is preferable for large, single settings.

Diamond shapes can vary significantly, and the unique characteristics determine quality for each kind of shape. Prices also vary based on supply and demand. Some of the shapes diamonds come in include:

  • Round
  • Princess
  • Emerald
  • Asscher
  • Marquise
  • Oval
  • Radiant
  • Pear
  • Cushion
  • Heart

Round cut diamonds are the most popular due to their incredible brilliance, fire, and light performance. Princess cut diamonds are the second most popular, featuring an elegant geometric shape.


Diamonds occur in a variety of colours including white, blue, yellow, orange, red, green, pink, purple, brown, and black. Colouring is caused by interstitial impurities or structural defects. Pure diamonds are perfectly transparent and colourless and are traditionally the most valuable. However, coloured diamonds are increasingly popular as a way for wearers to express their unique style.

Some colours like red, blue and pink are extremely rare and expensive. The Argyle mine in Western Australia supplies over 90% of the world’s pink diamonds. However, only a fraction of the diamonds found in these mines are pink, making Argyle pink diamonds extremely rare and sought after.
