Pink Diamond Buying Guide – From Origin to Jewellery
A pink diamond is a rare and unique gem, embodying elegance and individuality. Whether you are an investor in rare gems or a consumer of fine jewellery seeking a one of a kind experience, understanding the journey of pink diamonds, from their inception to their final setting, can help you confidently make the right purchase.
In this guide, we uncover what you need to know about pink diamonds including, natural pink diamonds versus lab-grown alternatives, what determines their worth, and how they stack up against other gemstones like rubies.
They have an interesting geological history. Unlike other coloured diamonds that are coloured due to chemical impurities (such as nitrogen in the case of yellow diamonds), these rare gems owe their colour to a distortion in the crystal structure while the diamond was still being formed. This distortion of the crystal structure causes the light to reflect differently, which produces the gemstone’s characteristic colour.
Natural pink diamonds are most commonly found in Australia’s now-closed Argyle mine, previously the world’s top producer of these gems, and secondarily in Russia, South Africa, Brazil, and Canada. These rare gems, especially with this closure, have become even rarer, which continues to have a strong impact on the valuation of these diamonds.
Both rubies and pink diamonds display romantic colours but differ hugely in material, cost, and hardness.
➤ Material : The gemstones are made of carbon, while rubies are a corundum mineral with a chromium chemical makeup, giving them their colour.
➤ Hardness : Diamonds are the hardest gem (10 on the Mohs hardness scale), making them more everyday friendly than rubies (9 on the Mohs hardness scale).
➤ Cost : These rare gems (superior quality) are more expensive than rubies, and pink diamonds are rarer than rubies and therefore, pricing is greatly affected.
➤ Brilliance : Diamonds have more light reflection and brilliance than rubies, including pink ones.
So, with this comparison of pink diamond vs rubies, it purely comes down to preference and budget. If rarity and inherent value are important to you, no other option than this exquisite gem can achieve this.
These gemstones can be featured in a range of jewellery types, including engagement rings, earrings, pendants, bracelets, and more! Their special romantic hues and limited supply make them a great option for bespoke and heirloom pieces.
Some Things to Consider When Buying Pink Diamond Jewellery :
1. Decide if you want natural or lab-grown : If you want it for investment purposes or as a collector’s piece, look for natural stones. If you’re concerned with affordability or sustainability, look for a lab-grown pink diamond for your perfect piece.
2. Obtain certification : Always buy diamonds that are certified by institutions like GIA, IGI, etc.
3. Pay attention to the cut and setting : The overall appearance of a smaller pink diamond can be enhanced with a halo or by placing it in a three-stone setting to improve the colour and size appearance.
4. Find a jeweller you can trust : Make sure you are working with a jeweller who understands how to handle rare stones, like these rare gemstones.
