What Are Lab Grown Diamond Engagement Rings?
Lab grown diamond engagement rings feature diamonds created in controlled laboratory environments using two primary methods: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). These man-made diamond engagement rings contain identical carbon crystal structures to natural diamonds.
The Federal Trade Commission officially recognizes lab created diamonds as real diamonds. They display the same fire, brilliance, and sparkle that make diamonds the preferred choice for engagement rings worldwide.
A gemologist cannot distinguish between a lab grown and natural diamond without specialized equipment. Both score 10 on the Mohs hardness scale and exhibit identical refractive indices.
How Are Lab Grown Diamonds Made?
HPHT Method: Mimics the natural diamond formation process by subjecting carbon to extreme pressure (about 1.5 million pounds per square inch) and temperatures exceeding 2,700°F. This process takes several weeks and produces diamonds often used for industrial purposes and fine jewelry.
CVD Method: Places a diamond seed in a chamber filled with carbon-rich gases. These gases are ionized into plasma, causing carbon atoms to attach to the seed layer by layer. CVD diamonds tend to have fewer metallic inclusions and offer greater control over the final product.
Most engagement ring diamonds today come from CVD processes due to better clarity outcomes and more consistent color grades.

Lab Grown vs Natural Diamond Engagement Rings
The debate between lab grown vs natural diamonds centers on value, ethics, and long-term considerations.
Feature | Lab Grown Diamonds | Natural Diamonds |
Chemical Composition | Pure Carbon | Pure Carbon |
Hardness | 10 Mohs | 10 Mohs |
Price | 60-80% Less | Full Market Price |
Resale Value | Limited | Higher Retention |
Environmental Impact | Lower | Higher |
Certification | IGI, GCAL | GIA, AGS, IGI |
Time to Create | 6-10 Weeks | Billions of Years |

Juli Church notes: “When customers ask me about lab grown versus natural, I tell them to focus on what matters to them personally. If you want the biggest, most brilliant diamond for your budget without ethical concerns, lab grown delivers. If generational value and rarity matter more, natural diamonds make sense.”
Benefits of Lab Grown Diamond Engagement Rings
Cost Savings Without Compromising Quality
Lab grown diamonds cost 60-80% less than comparable natural diamonds. A 2-carat lab grown diamond with excellent cut, E color, and VS1 clarity might cost $2,500-$4,000. The same specifications in a natural diamond would run $15,000-$25,000.
These savings allow couples to prioritize other financial goals, whether that means a larger stone, a better setting, or contributions toward a home purchase.

Ethical and Eco-Friendly Choice
Eco-friendly diamond jewelry appeals to environmentally conscious buyers. Lab grown diamonds require no mining, which eliminates habitat destruction, water pollution, and carbon emissions associated with traditional diamond extraction.
The Kimberley Process has reduced conflict diamond circulation, but concerns remain about labor practices in certain mining regions. Lab grown diamonds bypass these issues entirely.
Guaranteed Origin and Quality
Every lab created diamond comes with documented origin. Lab diamond certification from reputable grading laboratories like IGI or GCAL provides detailed specifications about cut, color, clarity, and carat weight.
How to Choose a Lab Grown Diamond Engagement Ring
Prioritize Cut Quality Above All
Cut determines how well a diamond interacts with light. Even a D-color, internally flawless diamond will appear dull with a poor cut. Look for Excellent or Ideal cut grades from IGI-certified diamonds.
Select the Right Diamond Shape
Diamond shape affects both appearance and price. Round brilliant cuts cost more due to greater rough diamond waste during cutting. Fancy shapes like oval, cushion, and radiant offer larger face-up appearances at lower prices.
Popular engagement ring shapes include:
- Round Brilliant: Maximum sparkle, classic appeal
- Oval: Elongating effect, excellent brilliance
- Cushion: Romantic, vintage feel
- Princess: Modern, geometric lines
- Radiant: Combines brilliance with rectangular shape
- Emerald: Step-cut elegance, hall-of-mirrors effect

Understand Color and Clarity Trade-offs
For lab grown diamonds, G-H color grades appear white to the naked eye and cost significantly less than D-E-F grades. Similarly, VS2 or SI1 clarity grades are typically eye-clean, meaning inclusions remain invisible without magnification.
Spending extra on D color or IF clarity rarely translates to visible differences in mounted rings.
Choose Your Setting Style
Ring settings dramatically impact overall appearance. Consider these popular options:
- Solitaire Setting: Timeless, highlights the center stone
- Halo Setting: Adds perceived size and extra sparkle
- Pavé Setting: Diamond-encrusted band for continuous brilliance
- Bezel Setting: Modern, protective metal rim

Case Study: Sarah’s 1.5 Carat Lab Grown Engagement Ring
Sarah, a 29-year-old marketing manager from Austin, shared her experience with LearningJewelry.com:
“My fiancé and I set a $5,000 budget for the engagement ring. At local jewelry stores, we found disappointing options—small diamonds with visible flaws, pushy salespeople, and zero flexibility.
After researching lab grown options, we purchased a 1.5-carat oval lab diamond (G color, VS2 clarity, Excellent cut) set in a white gold pavé band from James Allen for $3,800. The 360° video tool let us inspect multiple diamonds before choosing.
The ring arrived with IGI certification, and I genuinely cannot tell the difference from my friend’s natural diamond ring that cost $12,000. We used the savings toward our honeymoon fund.”
