What to Look for in a Pink Diamond

Some tips on investing in pink diamonds

The colour pink is a scientific enigma. It is neither a particle nor a wave; it does not exist in the visible spectrum. Yet, our eyes and brain perceive this exquisite pigment.

The presence of this hue in the diamond makes the gemstone a geological mystery. Scientists have come up with plausible rationales, but so far no one can tell the exact reason behind this phenomenon. The preciousness of diamonds and the enthralling roseate tone make for a truly captivating gemstone — a rarity of nature desired by many.

They are extremely rare and are, therefore, particularly expensive, it is worth knowing what to look for in a natural pink diamond before making a final purchase. Whether as a personal treasure or an investment piece, choosing the best pink diamond according to your interest and resources need not be so complicated.

A Rush of Blush

GIA grades natural pink diamonds according to how intense the rosiness is. Its hue begins from Faint to ranges of Light Pinks, and gradually goes to the richer saturation of Fancy Pinks. Argyle’s colour grading scale, meanwhile, consists of 4 pink shade classifications: Purplish Pink (PP), Pink (P), Pink Rosé (PR) and Pink Champagne (PC). This hue classification is followed by a number, from 1 – denoting the highest intensity of that particular shade, to 9 – indicating the lowest intensity.

Of all considerations when it comes to pink diamonds (and any other fancy coloured diamonds, for that matter), the central emphasis is given to colour intensity. The colour overrules all the other diamond grading factors, which is why even with quite visible inclusions, a vibrant pink diamond can still be handpicked for the premier Argyle Pink Diamond Tender.

As far as inclusion is concerned, a good rule of thumb is that the paler pink it is, the less visible inclusion it should have. Pink diamonds with higher colour intensity can certainly get away with eye-visible inclusions. Those with lower colour intensity, however, can’t have glaring inclusions, especially towards the centre of the stone.

Secondary hues also impact the value (and therefore, the pricing) of natural pink diamonds. Though its value increases the more intense and pure pink it is, the presence of a secondary hue may offset this rule. For example, a fancy pink diamond, which is highly valuable, may cost less than a lighter pink with the same carat weight, only for having this rare and gorgeous purple or red undertone.

When buying pink diamonds as an investment piece, you want to stick as much as possible to stones with a rich, rosy hue. These diamonds may cost so much; but in the long run, they are easier to sell and will fetch a higher selling rate, should you choose to sell in the future. High colour grade pink diamonds are more sought after than their paler counterpart.

Carats and Cuts

Carats and Cuts

It is extremely rare to find these breathtaking gems in high carats. It goes without saying that the pink diamonds in bigger carats command a higher price. Then again, it could still all depend on the richness of its hue. A smaller, Fancy Vivid Purplish Pink diamond may cost more than a bigger, Fancy Light Pink one.

The cut has the power to make the stone appear bigger than its worth in carat. The most skilled diamond cutter can even raise the value of the pink diamond twofold or more. The best cutting technique on a rough diamond can also elevate its brilliance no matter the colour and clarity grade.

When choosing pink diamonds, go for cuts that enhance its radiance and intensity. This is especially advisable for those who are looking to buy pink diamonds as a personal accoutrement or those on a set budget. The natural pink diamond may not be of a high carat or high colour grade, but the best cut will add to its overall appeal. It would not matter so much if the diamond is small; it will seem bigger and sparkle brighter than its actual size.

Synthetic and Enhanced Pink Diamonds

Synthetic and Enhanced Pink Diamonds

There is a reason why natural pink diamonds are coveted — they are a geological wonder. No amount of laboratory engineering can ever clone the novelty, stature, and superiority of magnificent pink diamonds from nature. Synthetic pink diamonds are risky because they can be difficult to resell, especially to discerning connoisseurs.

Pink diamond enhancements come in many forms. The most common are irradiation treatment to enhance appearance, laser drilling to remove distracting inclusions and fracture filling to treat internal cracks. Whilst these enhancements help fix issues present in the gemstone, alterations can lower the diamond’s value.

Enhancements may work for diamonds meant for personal use, but it is not recommended for investment purposes. Enhancements can negatively impact its value in the long run. Enhanced pink diamonds are generally sold at a reduced price.

Certified Versus Non-Certified Pink Diamonds

A thing of great value like natural pink diamonds warrants a certification from a reputable gemmological lab. This is an infallible way of knowing what you are getting. A certification defines and authenticates a specific piece of pink diamond beyond what the seller claims it to be.

The diamond certification includes characteristics such as the carat weight, colour grade, clarity grade, cut quality, and other details. It is also a way to know whether the gemstone is real or synthetic, or if it has undergone alterations or enhancements. These pieces of information are carefully assessed and validated by professional gemmologists of a third-party lab.

When buying pink diamonds, it is best to choose ones that come with a certification. The Argyle Diamond Investments Pty Ltd secures each piece of pink diamonds with an Australian certification, so you have full confidence with your purchase.
