Top 10 Questions to Ask When Buying a Lab-Grown Diamond
So you've already made the choice to go for a lab-grown diamond. Very good! 💎 Here are some essential questions you want to ask before you swipe that card to have a stunning ethical stone for a fair price.(Simple, jargon-free advice.)
🔍 1. "Could you please show me the diamond's certification report?"
Why it matters: Such certification (IGI or GIA) is the "birth certificate" of your diamond establishing authenticity, quality (4Cs), and that it has been lab-grown.✅ What you want: A report number showing the diamond's laser inscription.🚩 Never take the word "We don't have it" for "We don't have it," or for a click-and-bait uncertified certificate.
💰 2. "How much is the price per carat?"
Why it matters: Lab diamonds vary greatly in their prices. In judging true value, per carat is the norm over total price.✅ What you want: Full transparency: should be 40% to 80% less than natural diamonds.💡 Tip: Feel free to ask for discounts-may be on offer from several vendors!
🧪 3. "Which creation method was used to manufacture the diamonds: HPHT or CVD?"
Why it matters:
HPHT: Generally produces near-colorless diamonds much faster.
CVD: Usually gets purer white but then needs some form of post-growth treatment.✅ What you want : However, upon magnification, faint strain lines are often visible in CVD diamonds.
🌱 4. "Can you provide evidence to prove your sustainability claims?"
Why it matters: "Eco-friendly" became the latest buzzword. You must check!✅ What you want: Certificates about renewable energy use, carbon-neutral status, or water-recycling programs.🚩 Red flag: Statements such as "better for Earth" without any supporting data.
📏 5. "Can I see the diamond under magnification?"
Why it matters: Lab diamonds may come with peculiar inclusions (for instance, metallic flux in an HPHT diamond). You should get the opportunity to inspect the diamond in question!✅ What you want: Real-time videos/in-person viewing/360° images.💎 Pro tip: Request the plotting from the cert and compare.
🔄 6. "What about your return policy and warranty?"
Why it matters: What in the world if it's just not twinkling the way you had hoped? Or damage here and there?✅ What you want: At least 30 days for returns plus a lifetime warranty on manufacturing defects.
🛠️ 7. "Has this diamond been post-growtherially treated?"
Why it matters: Heat treatment is used on some CVD diamonds to improve their color. You have a right to know, but it's safe!✅ What you want: Disclosure; treatment must be disclosed on the cert.
💍 8. "Do you offer setting customization?"
Why it matters: Your diamond should be set into a dream ring!✅ What you want: Type of metal (like platinum, gold), kind of setting (such as solitaire or halo), and side stones.
⏳ 9. "What is the turnaround time for production and shipping?"
Why it matters: Custom rings do take time! Avoid last-minute panic.✅ What you want: Something concrete like 2–6 weeks with possibility for a rush option.
⚖️ 10. "How does your price compare to similar natural diamonds?"
Why it matters: To be sure you are really saving.✅ What you want: A concrete example:
Lab grown = 1.5ct, VS1, F color = $2,500Equivalent natural = $12,000+
✨ What to Bear in Mind:
Never be made to hurriedly make a statement. A highly reputable dealer must answer these questions in their entirety for you. If the seller tries to avoid answering or pressures you, walk away.
