LABORATORY-GROWN DIAMONDS
A new beginning.
A familiar brilliance.
Diamond, grown through innovation. Explore what laboratory-grown diamonds are, how they are created, and the details that matter when choosing one.
Begin with the essentials
The beauty is in the details. The difference begins at the origin.01 / THE ESSENTIALS
Yes, a diamond.
With a different origin.
Laboratory-grown diamonds are crystalline carbon, with essentially the same chemical, physical, and optical properties as natural diamonds. They are created in controlled conditions rather than formed within the Earth.
02 / THE SCIENCE OF A BEGINNING
Two paths to a diamond.
A seed. Carefully controlled conditions.
A crystal that can be cut and polished.
HIGH PRESSURE, HIGH TEMPERATURE
Pressure. Heat. Transformation.
HPHT uses high pressure and temperature to grow diamond from a carbon source around a diamond seed.
CHEMICAL VAPOR DEPOSITION
Growth, layer by layer.
CVD uses a carbon-containing gas in a low-pressure chamber. Carbon is deposited onto a diamond seed, building up diamond material.
Growth can be followed by additional treatment. Check the information available for the individual stone.
03 / A THOUGHTFUL COMPARISON
Understand the difference.
Choose what matters to you.
Both are diamonds.
Their growth histories are different.

| Identification | Specialized laboratory testing can establish origin; appearance alone is not reliable. | |
| Environmental claims | Ask for specific evidence about the producer and supply chain. Origin alone is not an impact assessment. | |
A comparison of origin and properties, not a promise about any individual product.
Know the stone.
Know its story.
04 / CHOOSE WITH CLARITY
A little clarity
goes a long way.
A laboratory report helps identify the stone and describe its characteristics. Read the individual report, rather than relying on a laboratory logo alone.
- 01
Confirm the origin
Look for clear laboratory-grown disclosure in the product description and any report provided.
- 02
Read what is assessed
Check measurements, weight, and quality information. Report terminology differs between laboratories and report types.
- 03
Verify the details
Use the issuing laboratory’s official report-check service. Ask about an inscription when one is present.
A LITTLE MORE UNDERSTANDING
A few things worth knowing.
Are lab-grown diamonds the same as moissanite?
No. Moissanite and cubic zirconia are diamond simulants: different materials that can resemble diamond. A laboratory-grown diamond is diamond, with a different growth origin from a natural diamond.
Can you tell the origin just by looking?
Appearance alone is not a reliable way to establish origin. A gemological laboratory uses specialized testing to distinguish laboratory-grown diamonds from natural diamonds.
Do all lab-grown diamonds look the same?
No. Individual stones vary in color, clarity, proportions, and appearance. View the actual stone where possible, and read its specifications and any available report.
Is laboratory-grown automatically a sustainable choice?
Origin alone does not establish environmental impact. Production energy, energy source, cutting, transport, and other factors can differ. Ask for specific, verifiable evidence behind any environmental claim.
Does every lab-grown diamond have a report?
Report availability depends on the stone and product. Check what is provided before purchasing. Formats vary: GIA’s current quality assessment for eligible colorless to near-colorless laboratory-grown diamonds uses Premium or Standard classifications; other laboratories may use different grading formats.
A PERSONAL CHOICE
Make the choice your own.
Explore with curiosity. Choose with confidence. Let the meaning be yours.
