More Diamond for Your Budget
Prioritize carat weight, color, clarity or the jewelry design itself with greater flexibility.

Lab-Grown Diamonds,
Clearly Explained.
Real diamonds. Modern origin. Exceptional possibilities.
The Difference Is Origin
A Diamond Is Defined by What It Is—Not Where It Formed.
Lab-grown and mined diamonds share essentially the same chemical composition, crystal structure and physical properties. Both can offer extraordinary brilliance, durability and beauty.
The fundamental difference is how they originate.
Real Diamond
Same Material.
Different Origin.
Lab-grown diamonds are not diamond simulants. They are genuine diamonds grown in controlled environments using advanced technology designed to reproduce the conditions necessary for diamond crystal growth.

Why Lab-Grown?
More Freedom to Choose What Matters to You.
A Real Diamond
Not cubic zirconia. Not moissanite. A genuine diamond with the fundamental material properties expected of diamond.
Exceptional Quality
High-quality lab-grown diamonds can offer outstanding brilliance, color, clarity and proportions.
No Diamond Mining Required
The diamond is created in a controlled environment rather than extracted from a diamond mine.
See the Difference?
Not Reliably by Simply Looking.
A beautifully cut lab-grown diamond can display the same kind of brilliance and visual beauty associated with a high-quality mined diamond. Specialized gemological testing can be required to establish origin.

Which Is Right for You?
Two Real Diamonds. Two Different Priorities.
Quality, Size & Design Freedom
- Real diamond
- Greater budget flexibility
- More carat-weight possibilities
- No diamond mining required
- More freedom for the complete jewelry design
Natural Origin & Geological Rarity
- Natural geological formation
- Traditional diamond provenance
- Natural scarcity and rarity
- Historical association with mined diamonds
What Lab-Grown Diamonds Are Not
Not a Simulant. Not a Substitute Material.
Not Cubic Zirconia
Cubic zirconia is a different material with different optical and physical properties.
Not Moissanite
Moissanite is a different gemstone and should not be confused with diamond.
Not “Fake”
A lab-grown diamond is a diamond. Its defining difference from a mined diamond is origin.
A Straightforward Note
What About Resale Value?
Neither fine jewelry nor diamonds should automatically be viewed as financial investments.
Lab-grown diamond prices have changed as production technology and supply have developed, and future resale value should not be assumed. Mined diamonds can have secondary-market value as well, but retail purchase price does not guarantee future resale value.
We recommend choosing a diamond primarily for what it means to you, how it looks, how it fits your budget and how you intend to wear it.

Questions
Lab-Grown Diamond FAQ
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are diamonds with essentially the same chemical composition, crystal structure and physical properties as mined diamonds. Their primary difference is origin.
Are lab-grown diamonds as durable as mined diamonds?
Yes. Both are diamond and are approximately 10 on the Mohs hardness scale, making them highly resistant to scratching and well suited to everyday fine jewelry.
Do lab-grown diamonds sparkle like mined diamonds?
Yes. A well-cut lab-grown diamond can display exceptional brilliance. Cut quality and proportions remain important to light performance.
Are lab-grown diamonds less expensive?
Typically, yes. Lab-grown diamonds generally sell for less than mined diamonds with comparable grading characteristics, although pricing varies by individual diamond and market conditions.
Can lab-grown diamonds receive grading reports?
Yes. Lab-grown diamonds can receive independent grading reports from recognized gemological laboratories that identify origin and relevant grading characteristics.
Are lab-grown diamonds environmentally better?
They avoid the need to mine the diamond itself. Broader environmental impacts can vary by producer, energy source, manufacturing location and supply chain, so specific environmental claims should be evaluated individually.
Can you tell a lab-grown diamond from a mined diamond by looking at it?
Not reliably in every case. Specialized gemological equipment and testing methods can be required to establish diamond origin.
