Materials & Authenticity

Authenticity is measurable: hallmarked solid gold, graded diamonds, and paperwork that says precisely what you own.

In short

DEEVE uses only solid 14K and 18K gold — never plated, never filled — set with lab-grown and natural diamonds. Lab-grown diamonds in engagement rings and studs are IGI-certified; eternity-ring and tennis-bracelet stones are IGI-graded without an individual certificate, because the piece is built from many small stones rather than one large one, so there is no single stone for a certificate to describe. Natural diamonds are conflict-free and responsibly sourced. Every piece is backed by a lifetime warranty.

Key takeaways

  • Solid gold means gold alloy from surface to core — repairable and refinishable indefinitely.
  • Lab-grown diamonds are real diamonds: Mohs 10 hardness, identical chemistry and optics.
  • 14K (58.3% pure) is harder for daily wear; 18K (75%) is richer in tone and softer.
  • Certification is recorded per piece; tennis bracelets and eternity bands are IGI-graded without an individual certificate; natural diamonds are not sold certified.

Transparency, quality, and integrity in every piece. DEEVE's commitment to solid 14K and 18K gold, lab-grown and natural diamonds, and ethical sourcing ensures you receive authentic, heirloom-quality jewelry — authored and guaranteed by Arta Talachian, Master Goldsmith & Certified Gemologist.

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. It can be polished, repaired, and refinished indefinitely, retains intrinsic value based on gold content, never wears off or reveals base metal, and is suitable for heirloom pieces passed down generations. Learn about gold purity comparison.

14K Gold (58.5% Pure)

14K gold offers the ideal balance of purity, durability, and value for everyday wear — our most popular choice for engagement rings, wedding bands, and daily-wear jewelry. Composition: 58.5% pure gold, 41.5% alloy metals, stamped with the 14K or 585 hallmark. Excellent durability, resistant to scratching, rich gold colour, hypoallergenic. Explore the Gold Education Hub.

18K Gold (75% Pure)

18K gold offers higher purity with a richer, more vibrant gold colour — ideal for those who prioritize gold content and luxurious appearance. Composition: 75% pure gold, 25% alloy metals, stamped with the 18K or 750 hallmark. Higher gold content, richer colour, excellent for sensitive skin, higher intrinsic value. How gold alloys affect quality.

Gold Colour Variations

We offer solid gold in three colours. Yellow gold — the traditional colour: warm, low maintenance, complements most skin tones. White gold — modern white finish, rhodium-plated, requiring periodic renewal every 1–3 years (care guide). Rose gold — romantic pink hue, slightly more durable, no plating required, develops a beautiful patina. Learn about alloy differences.

Gold Authenticity Guarantee

Hallmarked: stamped with the karat mark (14K/585 or 18K/750). Tested: verified for gold content before leaving our studio. Documented: certificate of authenticity included. Traceable: sourced from certified refiners. Guaranteed: backed by our lifetime warranty.

Lab-Grown & Natural Diamonds

We offer both lab-grown and natural diamonds. Our lab-grown diamonds are chemically, physically, and optically identical to mined diamonds; across our engagement rings and diamond stud earrings they are IGI-certified, while lab-grown diamond tennis bracelets and eternity bands are IGI-graded but ship without an individual certificate, because the piece is built from many small stones rather than one large one, so there is no single stone for a certificate to describe. Our natural diamonds are conflict-free and responsibly sourced.

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 (Mohs 10), same optical properties, same durability. The only difference is 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) deposits carbon-rich gas layer by layer to build the diamond crystal structure. Process differences.

Why Lab-Grown?

Environmental: minimal land disruption, lower carbon footprint, reduced water consumption. Ethical: 100% conflict-free with complete transparency. Value: 50–80% less expensive than comparable natural diamonds — larger, higher-quality stones for your budget. Environmental impact analysis.

Natural Diamonds

Alongside lab-grown, DEEVE offers natural diamonds across engagement rings, wedding bands, diamond studs, hoop earrings, and diamond necklaces. Responsibly sourced and conflict-free.

Diamond Certification & Grading

Our lab-grown diamonds in engagement rings and diamond stud earrings are independently certified by IGI (International Gemological Institute) using the same standards applied to mined diamonds — a comprehensive grading report with the 4Cs assessment, laser inscription on the diamond girdle, and a unique report number for online verification at igi.org. Lab-grown diamond tennis bracelets and eternity bands are IGI-graded (F–G colour, VS2–SI1) but ship without an individual certificate because the piece is built from many small stones rather than one large one, so there is no single stone for a certificate to describe — whatever its total carat weight. Natural diamonds are conflict-free and responsibly sourced. IGI certificate field-by-field explained · Understanding certification · View Diamond Certificates & Grading Reports.

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

Product Photography

Our product images come from our manufacturing partner's catalogue, which includes both photography and digitally rendered images. The specification table on each product page is the authoritative description of the piece you receive.

What We Don't Use (And Why)

Gold plated — never. A thin layer (0.5–2.5 microns) over base metal that wears off within months to years, reveals base metal, cannot be repaired, and has no intrinsic value. Why plated jewelry fails.

Gold filled — never. A thicker layer (5% of weight) bonded to base metal — it still wears through, has limited repairability, and is 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 our lifetime warranty.

What this means

  • Solid 14K and 18K gold, never plated

    Gold alloy through the entire piece, hallmarked 14K/585 or 18K/750 — no plating, no filling, no vermeil. There is no layer to wear off.

  • IGI graded, and said precisely

    Whether a piece includes an individual IGI certificate is recorded per piece and stated on its listing. Tennis bracelets and eternity bands are IGI-graded to the same standard without an individual certificate, because the piece is built from many small stones rather than one large one. Natural diamonds are not sold certified.

  • What we don't use

    No gold plating, no gold fill, no vermeil — coatings wear through and cannot be repaired or refinished the way solid gold can.

  • Conflict-free sourcing

    Lab-grown diamonds are mining-free by origin; natural diamonds are conflict-free and responsibly sourced.

FAQ

Questions, answered.

How can I tell if my gold jewelry is real?
Look for hallmark stamps: 14K or 585 for 14-karat gold, 18K or 750 for 18-karat gold. Solid gold will not discolor, tarnish, or wear off to reveal base metal. All DEEVE pieces are hallmarked and include a certificate of authenticity. If you're unsure, a jeweler can test gold content with an acid test or XRF spectrometer.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. Both are pure carbon in a cubic crystal structure with the same hardness (Mohs 10), refractive index (2.417), and optical properties. The only difference is origin. Gemologists require specialized equipment to distinguish them. Across our engagement rings and diamond stud earrings, every lab-grown diamond is IGI-certified; lab-grown diamond tennis bracelets are IGI-graded (F–G colour, VS2–SI1 clarity) but ship without an individual certificate — a tennis bracelet is many small stones, not one large one.
What is the difference between 14K and 18K gold?
14K gold contains 58.3% pure gold and is the industry standard for fine jewelry durability — harder, more scratch-resistant, and better suited for everyday wear. 18K gold contains 75% pure gold, offering a richer yellow tone but is softer. Both are solid gold throughout — never plated or filled. For everyday rings and bracelets, 14K is recommended. For special occasion pieces, 18K is a beautiful choice.
Do DEEVE lab-grown diamonds come with certificates?
Our lab-grown diamonds in engagement rings and diamond stud earrings include an IGI (International Gemological Institute) certificate with full 4Cs grading (cut, color, clarity, carat), a unique report number, and laser inscription on the girdle, verifiable online at igi.org. Lab-grown diamond tennis bracelets are IGI-graded (F–G colour, VS2–SI1 clarity) but ship without an individual certificate — a tennis bracelet is many small stones, not one large one. Natural diamonds are conflict-free and responsibly sourced.
Why doesn't DEEVE use gold plated jewelry?
Gold plating is a thin layer (0.5–2.5 microns) over base metal that wears off within months to years, revealing the base metal underneath. It cannot be repaired or refinished and has no intrinsic gold value. DEEVE uses only solid 14K and 18K gold — gold content throughout the entire piece — ensuring your jewelry can be polished, repaired, and worn for generations.
Where is DEEVE jewelry made?
DEEVE designs are developed and quality-inspected in-house by Arta Talachian, Master Goldsmith & Certified Gemologist, with 25+ years of experience; custom and bespoke pieces are handcrafted in our Ontario, Canada studio. Every piece passes in-house quality inspection before shipping; custom orders are checked at every stage — CAD model, casting, hand-finishing, and stone setting.
Does DEEVE offer natural diamonds?
Yes. DEEVE offers both lab-grown and natural diamonds. Natural diamonds feature across our engagement rings, wedding bands, diamond studs, hoop earrings, and diamond necklaces; lab-grown diamonds appear in engagement rings, wedding rings, diamond studs, and tennis bracelets. Natural diamonds are conflict-free and responsibly sourced.
