Lab Grown vs Natural Diamonds: What You Need to Know Before You Buy
Share
Introduction
Diamonds are a symbol of love, luxury, and legacy, but today’s buyers face a new choice: lab grown or natural? With technological advancements and shifting values, lab created diamonds are rising in popularity.
In this guide, we’ll explore everything you need to know about lab grown vs natural diamonds, and why Avira Diamonds is leading the way with ethically crafted lab grown jewellery.
Natural Diamonds
Natural diamonds are formed over billions of years deep within the Earth’s mantle under extreme pressure and heat. They are mined, cut, and polished to become the gemstones we know today.
Pros of Natural Diamonds
- Unique origin and rarity
- Long-standing traditional value
- Higher resale value (in some markets)
Cons of Natural Diamonds
- Expensive due to mining and rarity
- Ethical and environmental concerns
- Often, less transparent sourcing
Lab Grown Diamonds
Synthetic diamonds are created in laboratories using high-tech processes that replicate the natural diamond formation. In every measurable way, physically, chemically, and optically, these diamonds are indistinguishable from their natural counterparts.
Types of Lab Grown Diamonds
- HPHT (High Pressure High Temperature)
- CVD (Chemical Vapour Deposition)
Explore the types of lab grown diamonds.
Pros of Lab Grown Diamonds
- Ethically and environmentally friendly
- Cost-effective (up to 70% less expensive)
- Identical in brilliance and durability
Cons of Lab Grown Diamonds
- Lower resale value
- Perceived as “less romantic” by traditional buyers

Quick Overview between Natural and Lab Grown Diamonds
| Aspect | Lab-Grown Diamonds | Natural Diamonds |
|---|---|---|
| Origin | Man-made in laboratories (HPHT or CVD methods) | Formed naturally in Earth's mantle over billions of years |
| Chemical Composition | Pure carbon (same as natural) | Pure carbon |
| Physical Properties | Identical (hardness, refractive index, etc.) | Identical (hardness, refractive index, etc.) |
| Visual Appearance | Indistinguishable to the naked eye | Indistinguishable to the naked eye |
| Formation Time | A few weeks to a few months | 1–3 billion years |
| Cost | 30–70% less expensive | Higher due to rarity and natural origin |
| Environmental Impact | Lower (less energy, water, and land use) | Higher (mining impacts ecosystems and uses more resources) |
| Ethical Considerations | Conflict-free, more transparent sourcing | Possible association with conflict zones unless ethically sourced |
| Resale Value | Typically lower, limited secondary market | Generally higher, well-established resale and trade-in markets |
| Certification | Certified by IGI, GIA, AGS, etc. (must specify lab-grown) | Certified by IGI, GIA, AGS, etc. |
| Inclusions & Imperfections | Can be more consistent; sometimes fewer inclusions | Natural inclusions; unique "fingerprints" from Earth |
| Rarity | Not rare (can be reproduced indefinitely) | Rare due to geological formation conditions |
| Availability | Easily available in various sizes and qualities | Limited availability, especially for high-quality large stones |
| Market Perception | Seen as a tech-driven, modern, sustainable option | Viewed as classic, luxurious, and a symbol of timeless value |
| Use in Jewellery | Increasingly popular in engagement rings and fashion jewellery | Traditional choice for fine and high-end jewellery |
| Customization | Easier to customise in terms of size, colour, and clarity | Customisation is limited by natural supply |
Physical and Chemical Differences: Are There Any?
Surprisingly, no. Lab grown and natural diamonds are chemically and optically identical. Only advanced gemological equipment can differentiate them.

Price Comparison: Lab Grown vs Natural
Man-made diamonds are typically 30–70% less expensive than natural diamonds of comparable size and quality. This allows buyers to opt for larger or higher-grade stones within the same budget.
Ethical and Environmental Considerations
Lab grown diamonds are produced without the destructive environmental impact of mining or the risk of unethical labour practices. Avira Diamonds, for instance, ensures 100% conflict-free diamonds and sustainable sourcing.
Durability and Longevity
Both diamond types rank 10 on the Mohs scale of hardness, making them suitable for daily wear and lifelong use. You can count on lab-grown diamonds for the same incredible durability and lasting beauty.
Certification and Grading
Both lab grown and natural diamonds are graded by reputable institutions like GIA and IGI. Avira Diamonds offers full certification with every purchase to ensure quality and authenticity.

Resale Value and Investment
While natural diamonds have historically retained better resale va+++lue, the market is changing. Lab grown diamonds may not offer the same return, but their affordability and ethics attract modern buyers.
Aesthetic Differences: Can You Tell the Difference?
To the naked eye, no. engineered diamonds are indistinguishable from natural diamonds in sparkle, brilliance, and fire.
Market Trends and Consumer Preferences
More consumers, especially Gen Z and Millennials, are choosing lab grown diamonds for their sustainability, value, and modern appeal.
Celebrity Endorsements and Cultural Shift
Celebrities like Meghan Markle and Leonardo DiCaprio have helped promote lab grown diamonds as stylish and conscious choices.
How to Tell If a Diamond is Lab-Grown
| Method | Description | Who Can Do It |
|---|---|---|
| Certification Check | Look at the diamond’s grading report (e.g., GIA, IGI). Lab-grown diamonds will be clearly labeled. | Jewelers, consumers |
| Laser Inscription | Many lab-grown diamonds have a microscopic laser inscription on the girdle (viewable under 10x magnification). | Jewelers, trained buyers |
| UV Fluorescence | Some lab diamonds, especially CVD types, show different fluorescence under UV light. | Gemologists |
| Inclusions Under Microscope | Natural diamonds often have organic-looking inclusions; lab-grown ones may show metallic or structured inclusions. | Gemologists |
| Type IIa Testing | Many lab diamonds are Type IIa (rare in nature). Spectroscopic equipment can detect this. | Gem labs |
| Phosphorescence | Some HPHT diamonds glow (phosphoresce) after UV exposure, which is uncommon in natural stones. | Specialized testing required |
| Advanced Gem Testing | Instruments like DiamondView, FTIR, or Raman spectroscopy can definitively identify growth patterns. | Professional gem labs (GIA, IGI, etc.) |
What You Can Do as a Consumer:
- Ask for the Certificate – Always buy certified diamonds and check if it says "Lab-Grown" or "Synthetic."
- Use a Jeweller's Loupe (10x) – Look for any laser inscription on the girdle.
- Get It Professionally Tested – If in doubt, take it to a certified gemologist or lab (GIA, IGI, etc.).
