What to Look for in a Pink Diamond Engagement Ring

There are few things as rare as true and abiding love… the kind of love that makes you weak at the knees for years on end and sees you spending the rest of your life with that one perfectly imperfect person. The kind of love that makes you want to ask someone to make you the happiest person on earth by agreeing to marry them, or by saying that one little word… “Yes!” The kind of love that makes you want to signify its rarity with a token that is as rare and special as your relationship is.

An engagement ring is an enduring symbol of commitment, and it almost goes without saying that you want it to be beautiful, significant, unique, and treasured; you want it to encapsulate your feelings, your hopes, and your dreams; you want it to epitomise your love. So, how do you find the perfect engagement ring to convey all of that meaning? The answer is simpler than you might think.

Pink diamonds

Pink diamonds

Pink diamonds from the Argyle diamond mine in Western Australia are one of the rarest forms of diamond, and one of the most beautiful. They are one of the most expensive natural commodities on earth and, due to their increasing scarcity, they are widely considered to be quickly becoming one of the most concentrated forms of wealth in the world.

Why ‘Pink’?

Pink is a colour that emanates femininity and embodies love, romance, tenderness. This symbolism is transferred to pink diamonds, which bespeak these qualities in the rarest and most beautiful way. Pink diamonds also have an aura of mystery surrounding them – there is still some conjecture amongst experts about these rosy- and candy-coloured gems got their unique colouration, and this only adds to their appeal.

Why a Diamond?

Having a pink stone in your engagement ring conveys how highly you value these qualities, and how important they are in your relationship. Choosing a pink diamond tells your partner that you not only identify them with these characteristics, but that you see them as a rare and beautiful treasure. Selecting a distinctive pink diamond tells your partner that view them as being an irreplaceable, ‘one of a kind’ love.

Why are Australian Pink Diamonds so Special?

Why are Australian Pink Diamonds so Special?

Australian pink diamonds have always been considered incredibly rare. Over more than 30 years of operation the Argyle diamond mine has produced over 90% of the world’s supply of pink and red diamonds, yet this number represents the most minute portion of the world’s diamond supply, accounting for less than 1% of all coloured diamonds available.

The inherent rarity of Australian pink diamond affords these stones a high degree of intrinsic value and, due to their increasing scarcity, they are in consistently strong demand. Their higher purchase price means that good-sized gem-quality Australian pink diamonds make the perfect investment – set to continue to grow dramatically in value over the long-term, while also being incredibly robust in the current investment market and having great liquidity.

Having a high quality, distinctive pink diamond set into a one-of-a-kind, custom-made engagement ring creates an incredibly valuable piece that will become a dearly treasured heirloom that can be passed down through the generations of the family that you and your love will build together.

How Do You Choose the Right Pink Diamond for Your Engagement Ring?

How Do You Choose the Right Pink Diamond for Your Engagement Ring?


‘Fancy coloured’ pink diamonds aren’t governed by the same 4C’s that white or colourless diamonds are. While cut and size are still important, the grade of a fancy coloured diamond increases with its colour saturation. Other considerations in determining the grade of a fancy coloured diamond are the stone’s hue and tone. Essentially, the stronger, brighter, and more intense the colour, the rarer and, therefore, the more valuable the stone.

Hue and Tone

The hues, tones and saturation of colour found in Australian pink diamonds is what sets them apart from fancy coloured diamonds found in other part of the world. Australian pink diamonds display very distinctive red, purple and blue-based tones, compared to pink diamond sourced from other locations, such as India, Canada, Africa Russia, and Brazil. The Argyle in Australia mine has also yielded pink diamonds of much higher quality than those found elsewhere, making them far rarer and more valuable.

Colour Choice

The choice of colour, or hue and tone, is really a matter of preference when choosing a stone for an engagement ring. While a more vibrantly coloured stone will make for a better investment diamond, if you are purchasing an Australian pink diamond with the express intention of having it set into an engagement ring, or you are purchasing a ready-made pink diamond engagement ring, then it makes sense to prioritise the stone’s aesthetic value over its monetary value.

Some people will prefer a pale pink champagne to a bright pink diamond, while others would choose a deeply coloured purplish pink over a blush-coloured pink rose. While the price per carat will vary, depending upon the hue and tone, this is less of a consideration than choosing a stone that you or your partner will be happy to wear and will match the style and precious metal chosen for the ring.


The shape of the stone is a hugely important consideration when selecting an Australian pink diamond engagement ring. While white diamonds are most frequently shaped into round, brilliant cut stones to maximise refraction, a brilliant cut will often water down the colour of a pink diamond.

To maximise the colour and visual appeal of a fancy coloured diamond gem cutters will often cut stones into fancy shapes or play with the proportions of the diamond by making the girdle thicker or increasing the depth.

Again, when choosing an Australian pink diamond for an engagement ring, the shape will be a matter of personal preference. Some will prefer an elegant emerald cut over a pear or oval shaped diamond, while others may feel a heart shaped pink diamond is the best choice for an engagement ring. The best choice is the one that suits your personal sense of style, and your budget.

Stone Setting

When selecting a setting for a pink diamond, choose a style and precious metal that will maximise the impact of the stone. Many jewellers recommend setting paler pink champagne and pink rose diamonds in rose gold, and more vibrant pinks and purplish pinks in white gold or platinum. The aim here is to complement and highlight the colour of the stone, rather than detract from it or dull it down.

If you or your partner prefer a certain kind of precious metal, you may wish to choose a stone that complements the metal rather than vice versa, or you could use a combination of metals to suit both your preference and the stone. For example, if you prefer white gold but you have chosen a pale pink champagne diamond, you could use rose gold around the diamond and white gold for the remainder of the setting and the band.


This is possibly one of the more important factors to look at when purchasing a loose pink diamond or pink diamond engagement ring. Why? Well, certification is proof that you are getting the stone you have paid for.

Pink diamonds from the Argyle mine are certified and laser-inscribed, to prove authenticity, guarantee their provenance and confirm their grading on the Argyle scale. Argyle pink diamonds should also be issued with a GIA grading report that certifies that they have been examined and graded by GIA gemmologists and confirms that the stone is natural – that is, it has not been treated to enhance its colour and it is not laboratory grown.
