Is a Diamond a Good Investment? Let’s Put That Bling to the Test
There’s no denying the allure of diamonds. They dazzle on your finger, catch the light at every turn, and make you feel just a little bit like royalty. But beyond the glamour and sparkle, one question keeps popping up: Is a diamond a good investment?
For centuries, diamonds have been symbols of love, power, and wealth. But in a modern world that demands both style and strategy, you’re probably looking at diamonds through a new lens, as assets. So, does diamond make for a good investment, or is it simply a beautiful splurge wrapped in a velvet box?
Let’s dig deeper.
Is Buying a Diamond a Good Investment? The Real Deal Behind the Twinkle
Unlike stocks or gold, diamonds don’t have a standardised exchange or universally accepted pricing. Their value is influenced by what insiders call the 4 Cs: cut, colour, clarity, and carat, along with factors like origin, brand, certification, and design.
So when people ask whether buying a diamond is a good investment, the answer lies in how, where, and why you buy it.
Think of it as investing in wearable art. It’s not just about the returns, but the joy it brings every time you wear it.
Why Diamond Jewellery Can Be a Smart Investment (AKA the Pros)
If you’ve ever wondered, ‘Is diamond a good investment in today’s fast-changing world?’ The answer is yes, if you know what you’re doing. From their emotional pull to their global desirability, diamonds bring a rare blend of beauty and benefit to the table.
1. Tangible & Portable Wealth
Unlike stocks and digital assets, diamonds are physical. It’s something you can touch, wear, and admire. You can wear them, store them, and carry them discreetly, making them perfect for those who value privacy and portability.
2. Timeless Appeal
The market may fluctuate, but a classic solitaire or elegant diamond necklace never goes out of style. Diamonds offer emotional ROI, the kind of joy few other investments provide.
3. Inflation Hedge
In uncertain economic times, diamonds have historically held their value. While not immune to market dips, high-quality stones often ride out inflation better than cash sitting in a bank.

The Diamond Payoff: If you're buying a diamond as an investment, prioritise cut over carat. A smaller, perfectly cut diamond, like in our Vertical Boomerang Bali Earrings, can outshine (and outlast) a larger, poorly cut one. |
4. Dual Purpose: Beauty Meets Utility
Not many investments sparkle on your wrist at a gala or become family heirlooms. Diamond jewellery offers emotional value in addition to potential financial returns.
5. Increasing Global Demand
As affluence rises in parts of Asia, Africa, and the Middle East, so does the appetite for luxury goods, especially diamonds. A promising trend for long-term investors.
The Potential Risks of Investing in Diamonds
Is a diamond a good investment for everyone? Not always. While diamonds can be financially rewarding, they aren’t without their downsides. Here’s where it may lose some of its sheen:
1. Retail Mark-Ups & Resale Gaps
The price tag at a high-street boutique often includes a hefty mark-up. When you try to resell that same diamond, you may not recover the price you paid unless it’s a particularly rare or exceptional stone.
2. Liquidity Issues
Unlike shares or mutual funds, you can’t just “click to sell” a diamond. Finding the right buyer or appraiser takes time, and resale platforms can take a cut.
3. Lack of Price Transparency
There’s no global pricing index for diamonds. Unlike gold or silver, prices aren’t standardised. Two seemingly identical diamonds can have vastly different values.
4. Not All Diamonds Hold Value
Mass-produced jewellery or low-quality stones don’t appreciate. If you’re not selective, your purchase may hold more sentimental than financial value.
5. Insurance and Security Costs
Owning a high-value item means you’ll need to insure and protect it properly. That adds to the lifetime cost of ownership, even before you consider resale potential.

The Diamond Payoff: Looking to sell in the future? Stick to timeless designs like solitaires or tennis bracelets. They're easier to resell than trend-driven styles. |
Diamond Settings that make Smart investments
Your choice of setting matters, perhaps more than you think. The right setting can enhance value, wearability, and longevity, all of which impact investment potential.
1. Seamless Brilliance With the Invisible Setting
Invisible settings tuck diamonds side-by-side with no prongs or bezels, creating a flawless, uninterrupted surface. This style maximises sparkle and can elevate the perceived value of jewellery, especially when precision-cut stones are used. Bold, polished, and effortlessly sleek, the Gentleman's Oath Diamond Band is where craftsmanship meets charisma.
Why it’s smart: Invisible set pieces can be more cost-effective while still offering high visual impact, ideal for fashion-forward investors.
2. Strength and Unity with Composite Settings
Composite settings use several small diamonds arranged to mimic the appearance of a single larger gem. These are affordable upfront but create strong resale value due to their size and symmetry. Our Royal Rebel Noir Knight Oval Stud Earrings are bold yet understated, perfect for the rule breakers.
Why it’s smart: You get more shine for your spend, and when done well, composite designs age gracefully.
3. Bold Vintage Charm with Cluster Settings
Cluster settings form floral or starburst designs, often seen in vintage or antique jewellery. They're intricate, unique, and increasingly desirable among collectors. The Bling It On Ring is a standout piece that captures the essence of vintage glamour with a bold cluster of dazzling diamonds.
Why it’s smart: As vintage styles surge in popularity, cluster pieces may appreciate in both monetary and aesthetic value.

The Diamond Payoff: Rarity + Certification + Timeless Design = Resale Power. If your diamond ticks all three boxes, you’re holding something truly special. |
4. Best of Both Worlds with Diamond + Precious Metals
Pairing diamonds with precious metals like platinum, 18K gold, or rose gold can elevate the entire piece. Not only does the metal add intrinsic value, but certain combinations are more desirable on the resale market. Let our Tiara Royale Ring reign over your jewellery box and give you the best of both worlds.
Why it’s smart: A well-balanced metal-to-gem ratio can ensure long-term value retention, especially if certified by a reputable jeweller.
