What's better for an engagement ring: a natural diamond or a lab-grown diamond ? This is one of the most frequently asked questions we receive at BRAVORA. Both are real diamonds, with the same chemical composition and brilliance, but their differences in origin lead to variations in price, perceived value, and ethical standards . In this definitive guide, we'll help you make an informed decision.
What is a natural diamond?
A natural diamond forms deep within the Earth over millions of years, under extreme conditions of pressure and temperature. Its rarity has made it a symbol of exclusivity and tradition. However, diamond mining can be associated with environmental and social impacts if responsible sourcing is not guaranteed.What is a laboratory diamond?
A laboratory diamond is created under controlled conditions, replicating the same pressure and temperature process using methods such as HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) . Its chemical composition and optical properties are identical to those of a natural diamond: they are real diamonds, recognized and certified by international gemological laboratories such as GIA or IGI .Key differences between natural and laboratory diamonds
1. Average price per carat
The price difference is the main reason many customers consider a lab-grown diamond. On average, a lab-grown diamond costs between 30% and 60% less than its natural counterpart of the same size and quality.| Caratage | Lab Diamond (approx.) | Natural diamond (approx.) |
|---|---|---|
| 1.00 ct | 500 – 800 € | 4,500 – 6,000 € |
| 1.50 ct | 800 – 1,000 € | 8,000 – 12,000 € |
| 2.00 ct | 1,000 – 1,500 € | 15,000 – 20,000 € |
Approximate prices in 2025 according to IGI/GIA certification, quality VS1-VS2, color GH.
2. Value and resale
A natural diamond maintains a more stable resale value, while a lab-grown diamond tends to depreciate more quickly due to increasing supply and progressively lower prices. If investment value is your priority, a natural diamond remains more solid.3. Ethics and sustainability
At BRAVORA, we offer natural diamonds only upon request , and all diamonds are conflict-free through the Kimberley Process and certified ethically mined suppliers. If you choose a natural diamond, we ensure that it is not sourced from practices associated with "blood diamonds."Lab-grown diamonds, on the other hand, eliminate the risks associated with mining and represent a more eco-conscious and transparent option in their origin.
4. Shine, hardness and durability
There's no visible difference in brilliance or strength: both are diamonds with a hardness of 10 on the Mohs scale . Their durability is identical, and they're designed to last a lifetime.BRAVORA Tip: How to optimize quality-price
When it comes to natural diamonds, a key trick to keeping your budget under control is to choose VS1/VS2 clarity and GH color . We always recommend excellent cut, as it's a crucial characteristic for the gem's aesthetics and durability. These combinations offer the best balance between clarity, whiteness, and price, without compromising the diamond's beauty. The visual difference with higher grades (IF, D) is almost imperceptible to the naked eye, but the price difference can be enormous.Which one to choose for your engagement ring?
The decision depends on your priorities:- Choose a lab-grown diamond if you're looking for larger size and brilliance within your budget, with a guarantee of ethics and transparency.

Choose a natural diamond if you value tradition, social prestige, and better long-term resale performance.
