Lab-Grown Diamond FAQ

Lab-Grown Diamond FAQ

Everything you need to know about lab-grown diamonds

What Are Lab-Grown Diamonds?
Are lab-grown diamonds real diamonds?

Yes! Lab-grown diamonds are 100% real diamonds. They have the exact same chemical composition (pure carbon), crystal structure, and physical properties as diamonds formed in the earth. The only difference is where they were created.

What’s the difference between lab-grown and Moissanite diamonds?

Lab-grown diamonds are real diamonds made of pure carbon, while moissanite is a different gemstone made of silicon carbide. Though moissanite can be beautiful, it has different optical and physical properties than diamonds.

Lab-grown diamonds: Pure carbon, 10 on Mohs scale, identical to mined diamonds
Moissanite: Silicon carbide, 9.25 on Mohs scale, different refractive properties and “rainbow fire” effect

How are lab-grown diamonds made?

Lab-grown diamonds are created using two main methods:

HPHT (High Pressure High Temperature): Mimics the natural conditions deep in the Earth using extreme pressure and heat.

CVD (Chemical Vapor Deposition): Uses a carbon-rich gas mixture to grow diamonds layer by layer in a controlled environment.

Both methods produce genuine diamonds in just 2-4 weeks!

Quality & Certification
Are lab-grown diamonds certified like mined diamonds?

Absolutely! Lab-grown diamonds are certified by the same prestigious gemological institutes that certify mined diamonds, including GIA (Gemological Institute of America), IGI (International Gemological Institute), and GCAL.

Each certificate details the diamond’s cut, color, clarity, and carat weight – the same 4 Cs used for all diamonds.

Do lab-grown diamonds sparkle the same as mined diamonds?

Yes! Since lab-grown diamonds have identical optical properties to mined diamonds, they display the same brilliance, fire, and scintillation. The sparkle is completely identical.

Can jewelers tell the difference between lab-grown and mined diamonds?

With standard gemological equipment, no. Jewelers need specialized, expensive machines to detect the microscopic differences. To the naked eye and standard diamond testing equipment, they are indistinguishable.

Do lab-grown diamonds come in different colors and cuts?

Yes! Lab-grown diamonds are available in all the same colors (from colorless to fancy colored) and can be cut into any shape – round, princess, emerald, oval, pear, and more. The variety is just as extensive as mined diamonds.

Value & Pricing
How much do lab-grown diamonds cost compared to mined diamonds?

Lab-grown diamonds typically cost 30-50% less than comparable mined diamonds. This means you can get a larger, higher-quality diamond for the same budget, or save significantly while getting the exact same beauty and quality.

Do lab-grown diamonds hold their value?

Like all diamonds, lab-grown diamonds are purchased primarily for their beauty and emotional value rather than as investments. The resale market for lab-grown diamonds is developing as they become more widely accepted.

Most people buy diamonds to enjoy them, not to resell them, making this less of a concern for the majority of buyers.

Why are lab-grown diamonds less expensive?

Lab-grown diamonds cost less because:

• No mining operations required
• More predictable supply
• Lower environmental and labor costs
• Shorter supply chain

The lower price reflects production efficiency, not quality – the diamonds themselves are identical.

Durability & Care
Are lab-grown diamonds as durable as mined diamonds?

Absolutely identical durability! Lab-grown diamonds have the same hardness rating of 10 on the Mohs scale – the hardest natural substance. They’re just as scratch-resistant and long-lasting as mined diamonds.

How do I care for lab-grown diamonds?

Care for lab-grown diamonds exactly the same way as mined diamonds:

• Clean with warm soapy water and a soft brush
• Store separately to prevent scratching other jewelry
• Have them professionally cleaned and inspected annually
• Remove during heavy physical activity

Will my lab-grown diamond last forever?

Yes! Lab-grown diamonds are just as permanent as mined diamonds. They won’t chip, fade, or change color over time. With proper care, they’ll maintain their beauty for generations.

Ethics & Environment
Are lab-grown diamonds more environmentally friendly?

Yes! Lab-grown diamonds have a significantly smaller environmental footprint:

• No mining required – no disruption to ecosystems
• Lower carbon emissions
• No displacement of communities
• Minimal water usage compared to mining operations

Are lab-grown diamonds conflict-free?

100% conflict-free! Since lab-grown diamonds are created in controlled laboratory environments, there’s no risk of funding conflicts or supporting unethical mining practices. You can be completely confident in the ethical sourcing of your diamond.

Buying Considerations
Should I choose lab-grown or mined diamonds?

The choice depends on your priorities:

Choose lab-grown if you value:
• Getting more diamond for your budget
• Environmental responsibility
• Guaranteed conflict-free sourcing
• Innovation and modern technology

Choose mined if you prefer:
• Traditional diamond creation story
• Established resale market
• The rarity factor

Remember: Both are real diamonds with identical beauty and quality!

Can I insure my lab-grown diamond?

Absolutely! Lab-grown diamonds can be insured just like mined diamonds. Most major insurance companies provide coverage for lab-grown diamonds based on their appraised value.

Will people know my diamond is lab-grown?

Only if you tell them! Lab-grown diamonds look identical to mined diamonds. Even experienced jewelers need specialized equipment to tell the difference. Your diamond will sparkle beautifully and draw compliments regardless of its origin.
