Materials & Authenticity

Transparency, quality, and integrity in every piece. Deeve's commitment to solid 14K and 18K gold, certified lab-grown diamonds, and ethical sourcing ensures you receive authentic, heirloom-quality jewelry backed by our five-generation expertise.

Our Materials Philosophy

At Deeve, we believe in absolute transparency about what goes into your jewelry. Every piece is crafted from solid 14K or 18K gold—never plated, never filled and set with certified lab-grown diamonds that are chemically, physically, and optically identical to mined diamonds. Our five-generation heritage means we understand materials at the molecular level, and we're committed to educating our customers about exactly what they're purchasing.

Solid Gold: 14K & 18K

We work exclusively with solid gold in 14K and 18K purity. Understanding the difference between gold purities and why we choose these specific karats is essential to appreciating the quality and durability of your jewelry.

What is Solid Gold?

Solid gold means the metal is gold alloy throughout the entire piece—not a thin layer plated over base metal. The gold content is consistent from surface to core, ensuring lasting value and durability.

  • Gold content throughout entire piece
  • Can be polished, repaired, and refinished indefinitely
  • Retains intrinsic value based on gold content
  • Suitable for heirloom pieces passed down generations
  • Never wears off or reveals base metal

Lab-Grown Diamonds: Certified & Ethical

We exclusively use certified lab-grown diamonds that are chemically, physically, and optically identical to mined diamonds. Our commitment reflects our values of environmental responsibility, ethical sourcing, and exceptional value.

What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds created in controlled laboratory environments that replicate natural diamond formation.

Identical to mined diamonds: Same chemical composition (pure carbon), same crystal structure, same hardness (10 on Mohs scale), same optical properties, same durability.

The only difference: Origin—one is grown in a lab, the other formed naturally underground.

Scientific review →

How They're Created

HPHT (High Pressure High Temperature): Replicates conditions deep in Earth's mantle with extreme pressure and temperature.

CVD (Chemical Vapor Deposition): Carbon-rich gas deposits layer by layer to build diamond crystal structure.

Process differences →

Why Lab-Grown?

Environmental: Minimal land disruption, lower carbon footprint, reduced water consumption.

Ethical: 100% conflict-free, complete transparency, no human rights concerns.

Value: 30-40% less expensive, larger higher-quality stones for your budget.

What makes jewelry heirloom quality →

Repairability & Longevity

Solid gold construction ensures your jewelry can be maintained for generations: resizable, repairable, refinishable, designed for multi-generational wear.

Why repairability matters →

What We Don't Use (And Why)

❌ Gold Plated

Thin layer (0.5-2.5 microns) over base metal. Wears off within months to years, reveals base metal, cannot be repaired, no intrinsic value.

Why plated jewelry fails →

❌ Gold Filled

Thicker layer (5% of weight) bonded to base metal. Still wears through, limited repairability, not suitable for long-term wear.

✓ Solid Gold Only

14K and 18K solid gold throughout. Never wears off, can be polished indefinitely, retains intrinsic value, suitable for heirlooms, backed by lifetime warranty.

Frequently Asked Questions

How can I tell if my gold is real?

Look for hallmark stamps (14K, 18K, 585, 750). Solid gold will not discolor or wear off. All Deeve pieces are stamped and include certificates. Learn more about gold purity.

Are lab-grown diamonds real diamonds?

Yes, absolutely. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. Same hardness (10 on Mohs scale), brilliance, and durability. The only difference is origin. Read our scientific review.

What's the difference between 14K and 18K gold?

14K is 58.3% pure gold (more durable, better for daily wear). 18K is 75% pure gold (higher gold content, richer color). Both are solid gold throughout. See detailed comparison.

Do lab-grown diamonds come with certificates?

Yes, every Deeve diamond includes an IGI certificate with complete 4Cs grading, unique report number, and laser inscription on the diamond girdle. Learn about certification.

Why don't you use gold plated jewelry?

Gold plating wears off over time, revealing base metal. It cannot be repaired or refinished and has no intrinsic gold value. We use only solid gold to ensure your jewelry lasts for generations. Why plated jewelry fails.

Where is your jewelry made?

All Deeve jewelry is designed, cast, and finished in our Ontario, Canada studio. Our five-generation heritage ensures exceptional craftsmanship and quality control at every stage.
