Lab Grown Diamonds Versus Mined: The Truth About Prices, Quality, and the Future of Jewellery (2025 Update)
The debate over lab grown diamonds versus mined diamonds continues to shape the jewellery industry. With technological advancements, evolving consumer preferences, and economic shifts, understanding what sets these options apart is more important than ever.
As a London Diamond Specialist, I’ve witnessed firsthand how these trends have evolved. Whether you’re considering mined diamonds for their traditional allure or lab-grown diamonds for their affordability and eco-friendliness, this updated guide will help you make an informed decision.
Diamond Prices in 2025: What’s Happening?
Lab-Grown Diamond Versus Natural: Why Prices Matter
For the first time in decades, natural diamond prices are dropping. This shift is primarily driven by the rising popularity of lab-grown diamonds, claiming a larger market share. Additionally, the diamond trade operates in US dollars, meaning that currency fluctuations can influence your final price.
Despite falling prices, mined diamonds remain a significant investment, and understanding their unique characteristics is essential to making the right choice.
Lab-Grown Diamonds: An Affordable Alternative
Lab-grown diamonds have become increasingly accessible as more manufacturers enter the market. Today, they are typically priced at a third of the cost of mined diamonds. However, it’s crucial to understand that not all lab-grown diamonds are created equal.
The method used to grow a diamond has a direct impact on its quality and appearance:
- HPHT (High Pressure, High Temperature): Grows diamonds one at a time without enhancements, ensuring unmatched brilliance and durability.
- CVD (Chemical Vapor Deposition): Allows mass production, often involving treatments to improve colour and clarity. While cheaper, CVD diamonds may lack the natural sparkle of HPHT diamonds.
As a London Diamond Specialist, I always recommend HPHT-grown lab-grown diamonds for their unparalleled brilliance and longevity.
Where to Shop: Who Sells What?
Your choice of jeweller significantly impacts the diamonds available to you:
- High Street Jewellers: Few offer lab-grown diamonds and may adjust their pricing on mined diamonds by lowering grades or offering discounts.
- Online Retailers: Many now offer lab-grown diamond and natural diamond options. They provide written information but need more in-person guidance to make an informed choice.
- Independent Jewellers: Bespoke jewellers who craft pieces to order are uniquely positioned to offer both options with no stock bias. They can provide face-to-face, impartial advice tailored to your needs.
Lab-Grown Diamonds: Not All Are Equal
Lab-grown diamonds have gained popularity not only for their affordability but also for their eco-friendly appeal. However, understanding how they are grown is crucial to making the right decision.
HPHT vs. CVD:
- HPHT Diamonds: These are grown under high pressure and temperature, with each diamond crafted individually. They require no enhancements, ensuring their brilliance and quality last a lifetime.
- CVD Diamonds: While cheaper to produce, CVD diamonds often undergo treatments to improve their appearance, which may impact their long-term value and sparkle.
CVD diamonds are flooding the market due to overproduction, and their lower prices can be tempting. However, they often don’t match the performance of HPHT diamonds.
Why Lab-Grown Diamonds Are Winning Hearts
A Lab grown diamond offers a more sustainable and ethical alternative to mined diamonds. Best of all, they are visually indistinguishable from natural diamonds and won’t devalue your bespoke jewellery piece.
Lab-grown diamonds are a fantastic choice for those looking to balance quality, budget, and sustainability, especially when crafted with precision and care.
The Independent Jeweller Advantage
For decades, online retailers had the upper hand, leveraging buying power to offer diamonds at prices independent jewellers couldn’t match. But the landscape is changing. Falling diamond prices and the rise of lab-grown options mean bespoke jewellers can now compete fairly with online giants—offering a superior, personalised service.
An engagement ring is more than a symbol of your love; it reflects your unique story. By choosing an independent jeweller, you gain:
- Expert guidance on selecting the perfect diamond.
- The opportunity to customise every detail.
- A bespoke service that prioritises quality and craftsmanship over mass production.
However, despite the positive changes in mined diamond prices, these savings are sometimes passed on to consumers. Online pricing still needs to catch up in two key areas: the falling cost of diamonds and the shifting value of precious metals.
Precious Metals in 2025: Platinum Shines Bright
While diamond prices are becoming more competitive, the same can’t be said for precious metals—at least not when shopping online. Gold prices remain at record highs, making platinum a more cost-effective option. Surprisingly, many online retailers still price 18ct white gold higher than platinum, failing to pass this saving on to consumers.
Here’s why platinum is worth considering for your bespoke jewellery:
- Durability: Platinum is stronger and more resistant to wear and tear than gold, making it ideal for everyday wear.
- Hypoallergenic: Platinum is free from alloys that can irritate sensitive skin.
- Timeless Elegance: With its naturally white sheen, platinum doesn’t require rhodium plating, unlike white gold.
- Affordability in 2025: Despite being historically more expensive, platinum is now less costly than gold, offering exceptional value without compromising quality.
Working with an independent jeweller gives you access to accurate pricing and expert advice, ensuring you benefit from this significant shift in the precious metals market.

Frequently Asked Questions About Lab-Grown and Mined Diamonds
Q: What are the ethical differences between lab-grown and mined diamonds?
A: Lab-grown diamonds offer a more ethical choice. They are created in controlled environments, avoiding the environmental and social challenges often associated with mining. They also provide excellent value, saving money over a natural diamond without compromising quality.
If the allure and rarity of natural diamonds, with their billions of years of heritage and natural beauty, appeal to you, ensure they are responsibly sourced and Kimberley-protected. Alternatively, consider Canadian diamonds, renowned for their ethical and environmentally conscious mining practices.
Q: Are lab-grown diamonds suitable for engagement rings?
A: Absolutely! Lab-grown diamonds are identical to mined diamonds and offer the same durability, brilliance, and beauty. They are the perfect choice for a bespoke engagement ring.
Q: Should I consider resale value when choosing a diamond?
A: Jewellery should always be chosen for its beauty and personal significance, not purely as an investment.
Lab-grown diamonds are ideal for custom-made jewellery, offering exceptional quality and affordability, but are not suited for investment purposes. Similarly, jewellery with natural diamonds should not be purchased with the expectation of profiting from a future sale.
For those interested in diamond investments, it’s best to explore options like diamond investment funds, which focus on the trade and appreciation of specific high-value stones.
Q: Can lab-grown diamonds be insured?
A: Yes, lab-grown diamonds are treated as genuine diamonds and can be insured by all major insurance companies. Ensure your insurance covers loss, theft, and damage for comprehensive protection and peace of mind should the worst happen.
