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.
Topics covered:
The Origin of Pink Diamonds
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.
Natural vs Lab-Grown Pink Diamond
When it comes to buying this rare gem, it is important to understand how natural pink diamonds and lab grown pink diamond options differ.
Created naturally over billions of years, deep beneath the surface of the Earth. They are extremely rare and highly valuable. Their colour, origin and grading certification all contribute to their value.
Lab-grown pink diamonds are created in controlled, synthetic environments through advanced technology. They share the same chemical and physical properties as natural diamonds but are readily available at a lower price point. These are a fantastic substitute for natural colour diamonds if you are interested in aesthetics over investment or want an ethical, eco-friendlier alternative to mined diamonds.
What Determines Pink Diamond Value?
Pink diamond value depends on several key factors:
Colour : The deeper and more saturated the pink is, the more valuable it will be. In terms of grading, diamonds range from “Faint Pink” to “Fancy Vivid Pink.”
Carat weight : Larger stones are extraordinarily rare and demand the highest prices.
Clarity : The clarity of the rare gem, although important, will usually come after colour in value in these rare gems. Somewhere in clarity, some inclusions may be acceptable if the colour is strong.
Cut : A large part of the value of a diamond is related to how well it is cut; this will improve both its brilliance and colour.
Origin and certification : GIA-certified stones and diamonds from the Argyle mine offer prestige for provenance and usually more value.
Pink Diamond vs Rubies
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.
Choosing the Right Pink Diamond for Your Jewellery
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.
Are Pink Diamonds a Good Investment?
Due to their scarcity and the shuttering of main mines, natural pink diamonds have gained significant value appreciation in the past decade. Particularly those with Argyle certification are sought after. However, as with any luxury investment, it is imperative to buy from reputable sources and get certification for authenticity.
Lab-grown pink diamond jewellery, although not an investment asset in the traditional sense, offers great value and is excellent for ethical buyers and consumers who simply like the colour. Collectors and investors are still interested in high-quality coloured diamonds, particularly those with unique colours, origins, and rarity.
Making Your Choice
These rare gems are intriguing from their enigmatic beginnings underground to their inspirational shine in fine jewellery. Whether you choose a rare natural pink diamond or a beautiful lab-grown pink diamond, they each hold their unique love story to tell. Knowing about the pink diamond value, the differences between natural vs lab-grown pink diamonds, and how they compare in the pink diamond vs rubies question, will help you to make an informed and confident decision for yourself. No matter the style or budget, a pink diamond offers an unmatched blend of charm, elegance, and personal expression. They are not just a gem—they are treasured pieces of the earth that are timeless and a rare symbol of beauty.
