Lab Grown vs Natural Diamonds: Which Should You Buy?

The lab grown vs natural diamond debate is one of the biggest questions in jewelry today. Lab diamonds have exploded in popularity, but are they actually a good choice? We will give you an honest assessment. No sales pitch, just facts.

What Are Lab Grown Diamonds?

Lab grown diamonds (also called lab created, synthetic, or cultured diamonds) are real diamonds made in a laboratory. They have the same chemical composition, crystal structure, and physical properties as natural diamonds.

They are created using two methods:

• HPHT (High Pressure High Temperature): Mimics the natural diamond formation process
• CVD (Chemical Vapor Deposition): Grows diamonds layer by layer from carbon gas

Lab vs Natural: Side-by-Side Comparison

Price Difference

This is where lab diamonds really shine. You can expect to pay:

• Lab diamonds. 60-80% less than comparable natural diamonds
• Example: A 1.5ct lab diamond might cost $1,500-2,500, while a comparable natural diamond costs $8,000-12,000

Lab diamond prices have dropped dramatically since 2020 and continue to fall as production scales up. What cost $3,000 two years ago might cost $1,500 today.

Quality & Appearance

In terms of how they look:

• Visually identical. You cannot tell them apart with the naked eye
• Same 4 Cs. Both are graded on Cut, Color, Clarity, Carat
• Same sparkle. Light performance is identical
• Same durability. Both are 10 on the Mohs hardness scale

Resale Value

This is where natural diamonds have a significant advantage:

• Natural diamonds. Retain 50-70% of retail value and can appreciate for rare stones
• Lab diamonds. Currently have minimal resale value (10-30% at best)

Environmental & Ethical Considerations

The reality is more nuanced than marketing suggests.

• No mining required
• Require significant energy to produce
• Environmental impact depends on energy source

• Mining has environmental impact
• Kimberley Process has reduced conflict diamonds to less than 1%
• Mining provides jobs in developing economies

When to Choose Lab Diamonds

Lab diamonds make sense if:

• You want the biggest diamond for your budget
• You don't plan to resell
• Size matters more than investment value
• You prefer the idea of a lab-created origin
• You're buying fashion jewelry you'll update over time

When to Choose Natural Diamonds

Natural diamonds make sense if:

• Value retention matters to you
• You view it as a long-term investment
• Tradition and natural origin are meaningful
• You're buying an heirloom piece to pass down
• You want something with intrinsic rarity

Our Honest Recommendation

Whatever you choose, make sure it's certified by a reputable lab. For lab-grown diamonds, IGI is the leading authority. For natural diamonds, GIA is the gold standard.

Frequently Asked Questions

Can jewelers tell the difference?

Not with the naked eye. It requires specialized equipment. Both lab and natural diamonds come with certification stating their origin.

Will lab diamonds last as long?

Yes. They have identical physical properties. A lab diamond will last just as long as a natural diamond — forever.

Should I tell my partner it's lab grown?

Yes, always be honest. Many people specifically want lab diamonds. Others prefer natural. This should be a decision you make together.
