What Is a Natural Diamond?
Natural diamonds are formed deep beneath the Earth's surface over billions of years under extreme heat and pressure. After being mined, they are carefully cut and polished into the gemstones used in engagement rings, earrings, necklaces, and other fine jewelry.
Every natural diamond is unique, with its own internal characteristics and natural growth patterns, making each stone one of a kind.
Natural diamonds remain a popular choice for those who value rarity and geological history.
What Is a Lab Grown Diamond?
Lab grown diamonds are real diamonds created using advanced technology that replicates the natural diamond-growing process.
The two primary production methods are:
- HPHT (High Pressure High Temperature)
- CVD (Chemical Vapor Deposition)
These methods produce diamonds with the same chemical composition, crystal structure, hardness, and optical properties as natural diamonds.
Unlike diamond simulants such as cubic zirconia or moissanite, lab grown diamonds are genuine diamonds recognized by professional gemological laboratories.

Appearance: Is There Any Visible Difference?
One of the most common questions buyers ask is whether lab grown diamonds look different from natural diamonds.
The answer is no.
To the naked eye, both diamonds display the same:
- Brilliant sparkle
- Fire
- Scintillation
- Transparency
Even experienced jewelers cannot distinguish between them without specialized gemological equipment.
If both diamonds share the same cut, color, clarity, and carat weight, they will appear virtually identical in everyday wear.
Durability & Everyday Wear
Both natural and lab grown diamonds rank 10 on the Mohs Hardness Scale, making them the hardest gemstone available.
This exceptional hardness means both are suitable for:
- Engagement rings
- Wedding bands
- Necklaces
- Earrings
- Bracelets
- Daily wear jewelry
With proper care, either option can last for generations.
Price Comparison
Price is one of the biggest differences between lab grown and natural diamonds.
Lab grown diamonds typically cost 30–60% less than natural diamonds with comparable specifications.
This allows buyers to choose:
- Larger carat sizes
- Better color grades
- Higher clarity
- More elaborate settings
without increasing their budget.
For many customers, lab grown diamonds offer exceptional value while maintaining the same beauty and durability as natural diamonds.
Certification & Quality Assurance
Whether purchasing a lab grown or natural diamond, certification plays an important role in verifying quality.
A trusted grading report provides independent information about:
- Carat Weight
- Cut
- Color
- Clarity
- Polish
- Symmetry
At Lotus Diamond, selected diamond jewelry includes certificates from internationally recognized gemological laboratories such as IGI or GIA, giving customers confidence in every purchase.
