Have you ever stopped to think “why are diamonds so expensive?” This is a question that has likely crossed your mind and the answer is far more complex than just their natural beauty. While natural diamonds have a certain appeal, their price tag often reflects clever marketing and a carefully controlled supply, rather than their inherent value. So, how do you know if you’re paying for the sparkle or the story? Let’s dig in.
Why Are Diamonds So Expensive?
Diamonds have long been associated with luxury, romance and status. But their high price isn’t just due to their natural rarity. Here’s a breakdown of the key elements driving diamond prices:
Marketing and Perception
Marketing campaigns have shaped diamonds into traditional and emotional symbols of love, commitment and status. These strategies have made diamond engagement rings a cultural expectation, making diamonds feel aspirational and worth the high price. Even with alternative gemstones available, many still associate diamonds with prestige and lasting value. However, that’s only part of the story.
Mining and Production Costs
Extracting diamonds is an expensive and time-intensive process. The entire process from sourcing and mining to extracting and polishing requires large-scale operations, skilled labour and advanced technology, which is why natural diamonds are so costly.
At Angara, we oversee every step of your diamond jewellery creation, from sustainably sourcing gemstones to cutting and polishing them with expert care. By eliminating middlemen, we deliver your dream jewellery faster and with 30% more value.
Supply, Demand & The Illusion of Scarcity
While diamonds are found in nature, their supply is carefully managed. For years, major suppliers have controlled how many diamonds enter the market, ensuring that demand remains high. This controlled release creates a sense of rarity, making diamonds appear more valuable than they actually are. Additionally, larger and high-quality diamonds are genuinely rarer, commanding premium prices.
Quality Grading & Certification Costs
Diamonds are expensive because they undergo rigorous grading and certification. Each one is graded based on the diamond 4Cs—Cut, Colour, Clarity and Carat Weight—which determines its value. A well-cut, colourless and flawless diamond is much rarer and commands a higher price.
What’s more? Certification from respected institutions like the Gemological Institute of America (GIA) ensures quality and authenticity but also adds to the cost. The higher the grade, the more expensive the diamond.

The most expensive diamond is the Cullinan Diamond, which is considered more valuable than the priceless Kohinoor diamond. The Cullinan diamond is the largest rough diamond, originally weighing 3,106 carats and valued at around $400 million. |
How to Buy Diamond Jewellery With Great Value?
Buying diamond jewellery is an exciting investment, but getting the best value requires more than just choosing the biggest stone. Whether you’re shopping for a diamond engagement ring, a pendant or a pair of timeless studs, here’s how to make a smart and informed purchase:
1. Prioritize Diamond Cut
The most valuable diamond is the one that has exceptional cut, colour, clarity and carat weight. Of these, cut has the biggest impact on sparkle, so prioritize an excellent or very good cut. A near-colourless diamond (G-H grade) and slightly included clarity (VS1-VS2) offer great value without noticeable flaws. Opting for a slightly lower carat weight (like 0.90ct instead of 1.00ct) can also save money while maintaining the same visual appeal.
💎 Tip: A well-cut diamond will always appear more brilliant than a larger but poorly cut one.
2. Choose Certified Diamonds
Always buy diamonds with authenticity certification from reputable labs like the Gemological Institute of America (GIA), International Gemological Institute (IGI), or reputable, legit jewellers like Angara. These certifications provide an unbiased assessment of the diamond’s quality, ensuring you get exactly what you’re paying for. Be cautious of lesser-known grading reports, which may inflate quality claims.
💎 Tip: A certified diamond guarantees transparency and protects you from overpaying for lower-quality stones.
3. Consider Alternative Diamond Shapes
Round diamonds are the most popular—but also the most expensive. Choosing fancy shapes like oval, pear, cushion or emerald cuts can give you a larger-looking diamond for a lower price. Some shapes also hide inclusions better, allowing you to opt for a lower clarity grade without sacrificing beauty.
💎 Tip: Since diamond pricing varies based on shape, clarity and carat weight, it’s always smart to compare gemstones by price to find the best option within your budget.
4. Go for Lab-Grown Diamonds
One of the key reasons why diamonds are so expensive is their natural rarity, mining costs and controlled supply. However, lab-grown diamonds offer the same brilliance, durability and beauty as natural diamonds—for up to 80% less. These diamonds are created using advanced technology that replicates natural diamond formation, making them a sustainable and exceptional value alternative.
💎 Tip: If you want a larger or higher-grade diamond without the premium price, lab-grown is a brilliant choice.
