Lab Created Diamond Engagement Rings vs. Natural Diamonds: What You Need to Know

September 16, 2025 3 min read

The Creation Process: Lab vs. Nature

The journey of a diamond — whether grown in a lab or born deep within the Earth — defines its unique story.

Lab Created Diamonds

Produced using two primary methods:

CVD (Chemical Vapor Deposition)
A diamond “seed” is placed in a chamber filled with carbon-rich gas. Under heat, carbon bonds to the seedlayer by layer, forming a diamond crystal.

HPHT (High Pressure High Temperature)
A small diamond seed is exposed toextreme pressure and heat, mimicking the conditions in the Earth’s mantle to crystallize carbon around it.

Advantages of lab grown diamonds:

Consistent quality and purity
Faster production and customization options

Ethical and eco-conscious sourcing

Natural Diamonds

Natural diamonds form overbillions of years, deep within the Earth under intense heat and pressure. They are carried closer to the surface throughvolcanic activity via kimberlite pipes.

Their formation is awe-inspiring and entirely organic — butit’s alsounpredictable and resource-intensive.

Physical Characteristics: Identical Yet Different

Both lab created and natural diamonds are100% carbon, with the same crystal structure andMohs hardness of 10.

To the naked eye:

Both offeridentical brilliance and sparkle

Both arenearly indistinguishable in everyday wear

Under gemological analysis:

Lab Created Diamonds: May show growth marks or distinct fluorescence patterns

Natural Diamonds: Often haveunique inclusions reflecting their natural journey

These differencesdon’t affect beauty or durability — but they tell adifferent origin story.

Cost and Value: What You Should Know

One of the biggest decision factors for couples iscost vs. long-term value.

Lab Created Diamonds:

- 30–50% less expensive
- Great for maximizing size or quality on a budget
- Tend to depreciate faster over time

Natural Diamonds:

- Higherinitial cost
- Traditionally perceived as an investment piece
- Better resale value due to rarity

Iffuture resale value matters, natural diamonds are often preferred. But for many couples, thecost savings and ethical benefits of labcreated diamonds outweigh this consideration.

Ethical and Environmental Considerations

Ethics and sustainability play a growing role in modern engagements:

Natural Diamonds:

- Mining can lead toenvironmental damage, habitat loss, and soil erosion
- Risk of conflict diamonds if sourcingisn’t carefully verified

Lab Created Diamonds:

- Conflict-free by design
- Smaller carbon footprint with no large-scale land disruption
- Supply chain is more transparent and worker-safe

For couples prioritizingresponsibility and sustainability, lab created diamonds align naturally with their values.

Market Trends: Why Lab Diamonds Are Rising

Modern couples — especiallymillennials and Gen Z — are changing the engagement ring market:

Sustainability First –Many want purchases that reflect theirenvironmental values.

Affordability Without Sacrifice – Lab diamonds delivermore sparkle for the budget.

Changing Perceptions – The idea that “only natural diamonds are valuable” is fading aseducation and acceptance grow.

Retailers are responding byexpanding lab diamond offerings, signaling that this is not a passing trend but alasting shift in jewelry culture.
