💍 5. Mejuri

More mainstream “everyday fine jewelry” brand.

💎 6. VRAI

🧭 Quick reality check (important)

Very few brands are strictly 100% recycled gold + 100% lab-grown diamonds across every product category at all times. Most ethical jewelers fall into:

• Fully lab-grown diamond + recycled gold (rare, like Kimaï)

• Mostly recycled gold + mixed diamond sourcing (Mejuri, AUrate)

• Lab-grown specialists with recycled gold settings (VRAI, others)

💡 If you want the cleanest ethical setup

Look for this combination:

• “100% recycled gold ” (or “pre-owned / reclaimed gold”)

• “100% lab-grown diamonds ”

• “no mined diamonds anywhere in the line ”

• third-party certifications (B Corp, RJC, etc.)

If you want, I can narrow this down further based on:

• engagement rings vs everyday jewelry

• budget range

• minimalist vs bold styles

• or brands available in the US vs Europe

Just tell me 👍

These brands typically hold certifications (like B Corp) or adhere to high standards of environmental responsibility and ethical labor practices. The Good Trade +1

2. MiaDonna

• Metals: 100% recycled (gold, platinum, etc.)

• Diamonds: Lab-grown only

• Why it stands out: Strong social mission (reinvests profits into mining-impacted communities)

👉 Great if you want ethics plus measurable impact beyond sourcing.Source 1

🌿 Very close (recycled gold + lab-grown diamonds, but not always 100%)

These are still excellent—but slightly less strict depending on the piece.

3. VRAI

• Diamonds: Lab-grown only, made with renewable energy

• Gold: Uses recycled metals (not always explicitly 100% across all items)

• Why it stands out: One of the most sustainable diamond production systems (hydropowered)Source 1

4. Mejuri

• Gold: Mostly recycled

• Diamonds: Offers lab-grown options (not exclusive)

• Why it stands out: More affordable, everyday fine jewelrySource 1

5. Brilliant Earth

• Gold: ~93% recycled (working toward higher)

• Diamonds: Lab-grown + recycled + ethical mined

• Why it stands out: Strong traceability and large selectionSource 1

6. Plum Diamonds

• Gold: Recycled

• Diamonds: Lab-grown

• Why it stands out: Fully vertically integrated + audited facilitiesSource 1

⚠️ Important reality check

Even in the ethical jewelry space:

• “100% recycled gold ” is still relatively rare across entire collections

• Many brands mix:

• recycled + Fairmined gold

• lab-grown + natural diamonds

• Marketing can be vague—look for explicit wording like “100% recycled” and “lab-grown only”

✔️ Quick shortlist (strictest to more flexible)

• Strictest (both 100%) :
  → Kimaï, MiaDonna

• Strong but not always 100% across all items :
  → VRAI, Plum Diamonds

• More mainstream ethical options :
  → Mejuri, Brilliant Earth

If you want, tell me your budget and style (minimal, vintage, engagement rings, etc.), and I can narrow this down to the best specific pieces or collections that match those exact ethics.

These brands often offer custom or ready-to-ship engagement rings and fine jewelry, providing a fully transparent, lower-carbon alternative to traditional mining. The Good Trade +2

2. MiaDonna

• Uses 100% recycled metals (gold, platinum, etc.)

• Uses only lab-grown diamonds

• Certified B-Corp with strong social impact initiatives

👉 Also fully aligned—plus a big sustainability and charity component.Source 1

💎 Brands that are very close (but not strictly 100% in both categories)

These are still excellent ethical choices, but with slight caveats:

3. Plum Diamonds

• Uses recycled gold

• Uses lab-grown diamonds

• Vertically integrated + audited production

👉 Meets your intent, though “100% recycled” may not always be explicitly guaranteed.Source 1

4. Brilliant Earth

• Uses recycled precious metals (but ~93% recycled gold currently)

• Offers lab-grown diamonds (plus natural options too)

• Strong traceability and certifications

👉 Ethical, but not strictly 100% recycled gold across all products.Source 1

5. Mejuri

• Uses mostly recycled gold

• Offers lab-grown diamonds (alongside natural ones)

👉 Good everyday option, but not exclusive to lab-grown stones.Source 1

6. AUrate

• Uses 100% recycled gold

• Uses conflict-free diamonds (not exclusively lab-grown)

👉 Great for recycled gold purity, but not strictly lab-grown-only.Source 1

7. La Joya Jewelry

• Uses lab-grown diamonds

• Uses recycled metals when available

👉 Ethical focus, but not consistently 100% recycled gold.Source 1

🧭 How to evaluate “truly ethical” jewelry

When brands claim sustainability, check for:

• “100% recycled gold” (not just “recycled” or “partially recycled”)

• Lab-grown diamonds only (no mined stones in the catalog)

• Transparency about sourcing and manufacturing

• Certifications (B-Corp, Responsible Jewelry Council, etc.)

Using recycled gold reduces mining impact, while lab-grown diamonds avoid the environmental and human-rights issues tied to traditional mining.Source 1

✔️ Bottom line

If you want the strictest match to your criteria , go with:

• Kimaï → most design-forward, fully aligned

• MiaDonna → strongest ethical + social impact model

If you're okay with slight flexibility , brands like Plum Diamonds or Brilliant Earth expand your options significantly.

If you want, tell me your budget or style (minimalist, engagement rings, everyday pieces), and I can narrow this down to the best specific pieces or collections.
