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
14K Gold (58.3% Pure)
14K gold offers the ideal balance of purity, durability, and value for everyday wear. It's our most popular choice for engagement rings, wedding bands, and daily-wear jewelry.
Composition: 58.3% pure gold, 41.7% alloy metals. Stamped with 14K or 585 hallmark.
Benefits: Excellent durability, resistant to scratching, rich gold color, hypoallergenic, optimal value.
18K Gold (75% Pure)
18K gold offers higher purity with a richer, more vibrant gold color. Ideal for those who prioritize gold content and luxurious appearance.
Composition: 75% pure gold, 25% alloy metals. Stamped with 18K or 750 hallmark.
Benefits: Higher gold content, richer color, excellent for sensitive skin, premium luxury appeal, higher intrinsic value.
Gold Color Variations
We offer solid gold in three beautiful colors. Learn about alloy differences.
Yellow Gold
Traditional gold color. Warm appearance, low maintenance, complements most skin tones.
White Gold
Modern white finish. Rhodium-plated, requires periodic renewal (1-3 years). Care guide.
Rose Gold
Romantic pink hue. Slightly more durable, no plating required, develops beautiful patina.

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.
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.
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.
Diamond Certification & Grading
Every Deeve diamond is independently certified by IGI (International Gemological Institute) using the same standards applied to mined diamonds.
IGI Certification
Comprehensive grading report with the 4Cs assessment, laser inscription on diamond girdle, unique report number for verification.
The 4Cs Grading
Cut: Excellent to Ideal grades
Color: D-F (colorless) to G-H (near-colorless)
Clarity: VS2 to VVS1 (eye-clean)
Carat: Precise weight
Diamond Authenticity Guarantee
IGI Certificate: Independent third-party grading report
Laser Inscription: Unique report number on girdle
Verification: Certificate verifiable online
Documentation: Complete provenance details
Guarantee: 100% lab-grown diamond guarantee
Canadian Craftsmanship
Every Deeve piece is designed, cast, and finished in our Ontario studio. Our five-generation heritage combines traditional goldsmithing with modern precision technology.
In-House Production
Complete control from design to delivery: CAD modeling, casting, hand-finishing, stone setting by certified jewelers, quality inspection at every stage.
Quality Standards
Five-generation expertise ensures: precise alloy formulations, secure stone settings, smooth comfortable finishes, structural integrity for daily wear.
Repairability & Longevity
Solid gold construction ensures your jewelry can be maintained for generations: resizable, repairable, refinishable, designed for multi-generational wear.
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.
❌ 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.
