The debate around lab grown diamonds vs real diamonds has become more relevant as more buyers explore affordable and sustainable alternatives. Many people assume laboratory-created stones are fake, but that is not true. Lab grown diamonds share the same chemical composition and crystal structure as natural diamonds.
Both options offer excellent beauty and durability. However, they differ in origin, rarity, pricing, and long-term value. Understanding these differences helps buyers choose the right diamond for an engagement ring, wedding band, or fine jewelry.

What Are Lab Grown Diamonds?
Lab grown diamonds, also called man made diamonds, are created inside advanced laboratories using technology that replicates the natural diamond-growing process. Manufacturers primarily use two production methods.
The first is High Pressure High Temperature (HPHT), which recreates the extreme heat and pressure found deep within the Earth. The second is Chemical Vapor Deposition (CVD), which grows diamonds from carbon-rich gases under controlled conditions.
Both methods produce real diamonds rather than diamond simulants. Their hardness, brilliance, and optical properties match those of natural diamonds.
What Are Real Diamonds?
Real diamonds, often called natural diamonds, form beneath the Earth’s surface over billions of years. Intense heat and pressure transform carbon atoms into diamond crystals before volcanic activity brings them closer to the surface.
Mining companies extract these stones from open-pit mines, underground mines, or alluvial deposits. After mining, experts cut and polish the rough stones into finished gemstones. In discussions about lab grown diamonds vs real diamonds, the distinction lies in their origins and production methods.
Natural diamonds are valued partly because of their limited supply and geological history.
Lab Grown Diamonds vs Real Diamonds: Main Differences
Although both types are genuine diamonds, several important differences separate them.
Origin
Natural diamonds form naturally over geological time. Lab grown diamonds are created in controlled laboratory environments within weeks.
Price
Lab grown diamonds usually cost 30% to 70% less than natural diamonds of similar quality. The lower production cost makes larger stones more accessible for many buyers.
Rarity
Natural diamonds are finite because nature cannot quickly replace existing deposits. Laboratory production can increase supply, making man made diamonds less rare.
Resale Value
Natural diamonds generally retain resale value better than lab grown diamonds. However, resale prices for both are often lower than original retail prices.
Environmental Impact
Diamond mining can disturb ecosystems and consume significant resources. Lab production avoids mining but still requires considerable electricity. The environmental impact depends on the energy source used by the manufacturer.
Are Lab Grown Diamonds Real Diamonds?
Yes. Lab grown diamonds are real diamonds.
The United States Federal Trade Commission recognizes laboratory-grown diamonds as diamonds because they have the same physical, chemical, and optical properties as mined diamonds. Standard jewelry testing equipment also identifies them as diamonds rather than simulants.
The only reliable way to distinguish them is through advanced gemological testing.
Appearance and Sparkle
Many buyers wonder whether laboratory-grown diamonds sparkle less.
The answer is no. Both natural and lab grown diamonds display the same brilliance, fire, and scintillation if they have identical cut quality.
The cut influences sparkle more than the diamond’s origin. A well-cut diamond reflects light efficiently and appears brighter than a poorly cut stone regardless of whether it formed naturally or in a laboratory.
Durability and Hardness
Diamonds rank 10 on the Mohs hardness scale. Both natural and man made diamonds achieve this rating because they share the same crystal structure.
This exceptional hardness makes both suitable for everyday wear. Engagement rings, wedding rings, and heirloom jewelry can last for generations with proper care.
Regular cleaning and occasional professional inspections help preserve their appearance.
Diamond Certification
Independent grading laboratories evaluate both natural and laboratory-grown diamonds using the same quality standards.
The famous Four Cs include:
- Cut
- Color
- Clarity
- Carat weight
Organizations such as the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) issue grading reports for both categories.
Certification allows buyers to compare diamonds based on measurable characteristics instead of marketing claims.
Which Diamond Offers Better Value?
Value depends on your priorities rather than a universal answer.
Choose a lab grown diamond if you want:
- A larger diamond within your budget.
- High visual quality at a lower price.
- Modern production without mining.
Choose a natural diamond if you value:
- Geological rarity.
- Long-term collectability.
- Better resale potential.
Neither choice is objectively better. Each serves different buyer preferences.
Choosing a Round Brilliant Cut Diamond
The round brilliant cut diamond engagement ring remains the most popular engagement ring style worldwide because it delivers exceptional sparkle.
Its brilliance comes from precise proportions and carefully arranged facets that maximize light reflection.
Many shoppers ask how many facets in a round brilliant cut diamond. A standard round brilliant cut contains 57 facets if the culet is absent or 58 facets if a culet is present.
Another common question is how many facets does a round brilliant cut diamond have. The answer depends on whether the cutter includes a culet, but the traditional design typically features 57 or 58 facets.
Because cut quality affects sparkle more than origin, both natural and lab grown round brilliant diamonds can produce outstanding brilliance when expertly cut.
Can Jewelers Tell the Difference?
Experienced jewelers cannot reliably distinguish laboratory-grown diamonds from natural diamonds through visual inspection alone.
Professional laboratories use sophisticated instruments to identify growth patterns, trace elements, and fluorescence characteristics. Many laboratory-grown diamonds also contain microscopic laser inscriptions that identify their origin.
For everyday wear, the appearance remains virtually identical.
Buying Tips Before You Decide
Start by setting a realistic budget before comparing diamonds.
Review the grading certificate carefully and prioritize cut quality because it has the greatest influence on beauty. Compare color and clarity only after selecting an excellent cut.
Buy from reputable jewelers who provide transparent grading reports and clear return policies. If resale value matters, research current market trends for both natural and lab grown diamonds before purchasing.
Final Thoughts
The comparison between lab grown diamonds vs real diamonds is less about authenticity and more about personal priorities. Both are genuine diamonds with identical physical properties and outstanding durability.
Natural diamonds offer rarity and geological history. Man made diamonds provide similar beauty at a significantly lower cost. By understanding their differences in origin, pricing, certification, and long-term value, buyers can confidently choose the diamond that best fits their budget and expectations.
