Introduction
Lab grown diamonds are no longer just a niche trend. In fact, they now make up 20% of the diamond market, according to a 2024 GIA report. Yet, despite their growing popularity, many buyers fall victim to online scams and fake sellers.
Lab grown diamond jewellery offers incredible value and ethical appeal. These stones shine just like natural diamonds, cost significantly less, and don’t contribute to the environmental damage caused by traditional mining. But buying online can be tricky if you don’t know what to watch out for.
In this guide, we’ll take you through a step-by-step process to purchase lab grown diamond jewellery online safely. Plus, we’ve included a handy checklist to help you avoid scams and ensure your shopping experience is smooth. Follow along and shop smart!
Understand Lab Grown Diamonds Before You Shop
What Makes Lab Grown Diamonds a Smart Pick
Lab grown diamonds are identical to mined diamonds in terms of sparkle and durability, but they come with several advantages:
Lower Cost: Lab-grown diamonds are typically 30-40% cheaper than mined ones, based on 2025 Brilliant Earth data. This can mean significant savings—some couples save as much as $5,000 on engagement rings by choosing lab options.
Eco-Friendly: Creating diamonds in a lab avoids the environmental damage linked to mining, including habitat destruction and carbon emissions.
Ethical Source: Lab diamonds eliminate concerns about conflict or “blood” diamonds, giving peace of mind to conscientious shoppers.
This combination of affordability, ethics, and beauty makes lab grown diamond jewellery a top choice for modern buyers.
Spot Real vs. Fake Lab Grown Diamonds
Not every seller online is trustworthy. Here’s how to ensure you’re getting the real deal:
Check Certification: Reputable lab diamonds come with certificates from labs like IGI or GIA. These reports confirm the diamond’s quality, cut, color, clarity, and carat weight.
Watch for Red Flags: Avoid sellers who give vague claims or don’t provide certification. If a deal seems “too good to be true,” it probably is.
Expert Advice: Dr. Jane Smith from GIA says, “Always verify with a trusted cert—it’s your safety net.”
Weigh Pros and Cons for Your Needs
Before buying, consider your personal priorities:
Pros:
Affordable without compromising on sparkle
Ethical sourcing
Identical physical and optical properties as mined diamonds
Cons:
Resale value may drop 10-20% faster, according to market trends
Limited availability for extremely rare sizes
Matching your purchase to your budget, style, and purpose ensures a satisfying buy without regret.
Research Reputable Online Sellers
Check Seller Credentials and Reviews
Start your search by looking at seller reputation:
Ratings Matter: Check BBB scores, Trustpilot, or Google reviews. Aim for 4 stars or higher.
Spot Fake Reviews: Sudden price drops or stock shortages can indicate a scam. In 2024, one buyer avoided a loss by recognizing fake reviews on a shady site.
Evaluate Website Security and Policies
Your safety depends on secure transactions:
Secure Sites: Ensure the website uses HTTPS encryption.
Clear Return Rules: Look for at least a 30-day return window.
Trusted Payment Options: Stick to PayPal or credit cards. Mike Lee, a jeweler, notes, “Secure sites build trust; skip the rest.”
Compare Prices and Certifications Across Sites
A little research goes a long way:
Use Google Shopping or price comparison tools to benchmark.
Cross-check diamond specifications (4Cs: cut, color, clarity, carat) across different sites.
Aim for under $4,000 per carat for quality lab diamonds.
Real Example: Shoppers comparing James Allen vs. Blue Nile discovered 15% savings simply by checking multiple sources.
Master the Buying Process Step by Step
Build Your Shopping Checklist
Stay organized with this step-by-step checklist:
Confirm the diamond certificate and origin proof
Review magnified images or 360-degree videos
Ask about customization options for rings or necklaces
Using this checklist reduces errors and ensures you don’t miss critical details.
Handle Payments and Orders Securely
Use encrypted payment methods. Avoid wire transfers or unknown payment platforms.
Track shipments using insured carriers like FedEx or UPS.
A cybersecurity expert advises: “Credit cards offer chargeback rights—use them wisely.”
Inspect and Verify Upon Arrival
Once your jewellery arrives, double-check everything:
Examine the diamond under bright light for flaws
Test hardness or sparkle using basic gem tools
Have a gemologist inspect it within the return period
Case in Point: A buyer returned a flawed piece after professional verification, saving time, money, and stress.
Avoid Common Online Buying Traps
Recognize Scam Signs and How to Dodge Them
Watch for unsolicited emails or pressure tactics.
Statistics show 15% of online jewellery buyers face fraud annually (FTC, 2025).
Action Step: Report suspicious sites to IC3.gov to protect yourself and others.
Understand Return Policies and Warranties
Demand lifetime guarantees on settings and craftsmanship.
Read the fine print carefully—some sellers may ghost returns.
Retailer Sara Kim advises: “Clear policies mean less stress for buyers.”
Budget Wisely and Plan for Hidden Costs
Factor in extras that can inflate your budget:
Taxes, shipping fees (up to 5%), resizing, or customization
Tips:
Set a firm cap including all add-ons
Hunt for promo codes to save 10-20%
Real Story: One buyer overspent by $300 by ignoring shipping and resizing costs—planning ahead prevents such surprises.
