How to Add Lab Grown Diamonds to Your Jewelry Store

How to Add Lab Grown Diamonds to Your Jewelry Store: A Retailer's Complete Checklist

If you've been watching the numbers, you already know: lab grown diamonds for retailers aren't a trend — they're the new baseline. According to BriteCo's 2025 research report, lab-grown diamonds now account for more than 45% of all U.S. engagement ring purchases, up from under 10% just a few years ago. The Knot's 2026 Real Weddings Study found that 61% of couples purchased an engagement ring featuring a lab-created diamond — a 239% increase since 2020.

The question isn't whether to stock lab-grown diamonds. It's how to do it right — so you protect your margins, educate your team, and meet your customers where they already are.

This guide walks you through every step. Consider it a field-tested checklist from a wholesale partner that ships to retailers across the country every single day.

Understand the Market You're Entering

Before placing your first order, ground yourself in the data.

The global lab-grown diamond market was valued at $29.46 billion in 2025 and is projected to reach $91.85 billion by 2034, growing at a CAGR of 13.42%, according to Fortune Business Insights. In the U.S. alone, the market is estimated at $21.76 billion in 2025, with North America positioned as the fastest-growing region globally.

What's Driving Consumer Demand?

Three forces are converging:

1. Price transparency. By 2025, a 1-carat lab-grown diamond averages $1,000 or less, compared to approximately $4,200 for a natural 1-carat stone. Customers know this, and they're choosing bigger, higher-quality stones with the savings.
2. Generational shift. Two-thirds of Gen Z engagement ring buyers now choose lab-grown. Millennials are close behind. These aren't fringe buyers — they're your core demographic for the next two decades.
3. Ethical and environmental values. Lab-grown diamonds require no mining, produce minimal waste, and carry no conflict-sourcing concerns. For a growing segment of consumers, this matters as much as the 4Cs.

If your store doesn't carry lab-grown options, a significant share of walk-in customers will simply go elsewhere.

Evaluate Your Current Inventory and Customer Base

Not every store needs the same lab-grown assortment. Start by asking:

• What are your top-selling price points? Lab-grown diamonds let you offer dramatically larger stones at each price tier. A customer with a $3,000 budget can now consider a 2-carat center stone instead of settling for a smaller natural diamond.
• What shapes do your customers request most? Rounds and ovals dominate, but demand for elongated cushions, emeralds, and pear shapes is rising fast.
• Do you serve a bridal-heavy market, or is fashion jewelry your strength? Lab-grown diamonds are growing fastest in bridal, but non-bridal categories like tennis bracelets and everyday studs are surging as well.

Map your existing customer profile against the lab-grown opportunity. This will shape your initial buy.

Source from a Certified, Reliable Wholesale Partner

This is where most retailers either set themselves up for success or create problems they'll spend months fixing. Your wholesale partner determines your margin, your product quality, and — critically — your speed to market.

What to Look for in a Wholesale Lab Grown Diamond Supplier

Here's what separates a reliable B2B supplier from a risky one:

• Third-party certification. Every stone should come with IGI or GIA certification. No exceptions. Certification gives your customers confidence and protects you from quality disputes.
• Breadth of inventory. A supplier with a few hundred stones will leave you scrambling when a customer wants something specific. Look for partners carrying thousands of certified diamonds across a wide range of sizes, shapes, and qualities.
• Rare and specialty shapes. Consumer taste is diversifying. Having access to antique cuts — Old Mine, Old European, Hexagon — gives you a merchandising edge that big-box competitors can't match.
• Speed. In retail, every day a customer waits is a day they might buy elsewhere. Same-day shipping capability is a genuine competitive advantage.
• Technology integration. If your supplier offers API integration or CSV inventory downloads, you can sync their stock directly to your website or POS system — no manual data entry, no stale listings.

Guru Diam, for example, maintains an inventory of 11,000+ IGI and GIA certified lab-grown diamonds across 30+ shapes — including rare antique cuts — with same-day shipping from their New York office. Their API integration and CSV download tools let retailers connect inventory directly to their own platforms, which is the kind of infrastructure that saves hours every week.

Set Your Pricing Strategy

Pricing lab-grown diamonds is different from pricing naturals. The market moves faster, wholesale prices can shift, and your customers are often well-researched before they walk in the door.

Pricing Principles for Lab-Grown Diamonds

• Don't anchor to natural diamond markups. Lab-grown diamonds have a different cost structure. Applying the same keystone markup you'd use for naturals can price you out of the market — or, conversely, leave margin on the table.
• Price by value, not just cost. Customers are buying the look, the certification, and the story. A well-presented 2-carat IGI-certified lab-grown diamond in a custom setting commands a strong price, even at a fraction of the natural equivalent.
• Bundle strategically. Lab-grown diamonds pair naturally with custom settings. Offer setting + stone packages at attractive price points to increase your average order value.
• Monitor the wholesale market. Because lab-grown diamond pricing has seen downward movement over recent years, staying close to your supplier's current pricing ensures your retail pricing stays competitive. A supplier with a real-time online inventory — rather than static price lists — helps you stay current.

Train Your Sales Team

Your staff are the bridge between the product and the customer. If they can't confidently explain lab-grown diamonds, hesitation will kill sales.

Key Training Topics

1. The science. Lab-grown diamonds are real diamonds — chemically, physically, and optically identical to mined stones. They're produced using two methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Your team should be able to explain this in plain language without sounding like a textbook.
2. Certification literacy. Every staff member should be able to read an IGI or GIA lab-grown diamond report and explain the 4Cs — cut, color, clarity, and carat weight — to a customer. This builds trust instantly.
3. The value conversation. Train your team to present lab-grown diamonds as a choice , not a compromise. The data supports this: consumers are using the savings to buy larger, higher-quality stones. According to BriteCo data, the average lab-grown engagement ring center diamond increased from 1.31 carats in 2019 to 2.45 carats in 2025.
4. Handling objections. "Will it hold its value?" "Is it a real diamond?" "What's the difference?" Your team needs rehearsed, honest answers to these questions. Transparency builds loyalty.
5. Side-by-side presentation. If you carry both natural and lab-grown, teach your staff to present both options without bias. Let the customer's priorities — budget, size, ethics, sentiment — guide the recommendation.

Merchandise and Display with Intention

How you present lab-grown diamonds in your store communicates everything about how you value them.

Display Best Practices

• Don't hide them in a corner. If lab-grown diamonds are tucked into a secondary case, you're signaling to customers that they're a lesser product. Give them prominent, well-lit display space.
• Create a dedicated section — but also integrate. Consider a "Lab-Grown Collection" display for visibility, but also place lab-grown pieces alongside naturals in your bridal case. This normalizes the category.
• Use signage that educates. A small card explaining "What are lab-grown diamonds?" near the display answers questions before they're asked. Keep it factual, not defensive.
• Show the size advantage. Display a 1-carat natural next to a 2-carat lab-grown at comparable price points. This visual comparison is one of the most powerful sales tools in your store.

Extend Your Presence Online

Your website needs to reflect your in-store commitment. At minimum:

• Add a lab-grown diamond category page with filters for shape, size, color, and certification.
• Include educational content — a landing page explaining what lab-grown diamonds are, how they're certified, and why you carry them.
• If your supplier offers API or CSV integration, use it. Displaying real-time inventory from a partner like Guru Diam means your online catalog can feature thousands of stones without you carrying all of them in-house.

Offer Custom Jewelry to Maximize Margins

Here's where smart retailers pull ahead: pairing lab-grown diamonds with custom jewelry manufacturing.

When you can offer a customer a bespoke ring, pendant, or bracelet set with a certified lab-grown diamond, you're selling an experience — not just a commodity. Custom pieces carry higher margins than pre-set inventory, and they create emotional attachment that drives referrals.

Look for a wholesale partner that offers custom manufacturing with fast turnaround. Guru Diam, for instance, provides custom jewelry manufacturing in 7–10 days, which means you can promise your customer a one-of-a-kind piece without the multi-week wait that frustrates buyers.

Build Your Marketing Around the Category

Once you've stocked and trained, tell people about it.

• Update your Google Business Profile to include "lab-grown diamonds" in your product descriptions.
• Run targeted social ads featuring lab-grown engagement rings with clear price-point messaging. Size comparisons perform especially well.
• Send an email campaign to your existing customer list announcing the new collection. Frame it as expanding choice, not replacing anything.
• Create blog and video content explaining your lab-grown offerings. Educational content ranks well in search and positions your lab grown diamond jewelry store as a knowledgeable destination.
• Leverage your supplier's resources. Some B2B wholesalers offer marketing assets, product photography, and inventory feeds that make content creation easier.

Your Complete Retailer's Checklist

Here's every step in one place — print this out and work through it:

1. Research the market — understand lab-grown diamond growth trends, pricing, and your local competitive landscape.
2. Audit your current inventory — identify gaps where lab-grown diamonds would serve existing customer demand.
3. Choose a certified wholesale partner — prioritize IGI/GIA certification, broad inventory, rare shapes, fast shipping, and tech integration.
4. Request wholesale access — apply through your supplier's B2B platform to unlock retailer pricing and tools.
5. Set your pricing strategy — establish markups based on current wholesale pricing, not legacy natural-diamond margins.
6. Train your entire sales team — cover the science, certification, value positioning, and objection handling.
7. Update your store displays — create dedicated, well-lit lab-grown sections and integrate pieces into bridal cases.
8. Build your online presence — add lab-grown diamond pages, educational content, and live inventory feeds to your website.
9. Offer custom jewelry services — partner with a manufacturer who can deliver custom pieces in under two weeks.
10. Launch your marketing — update your Google profile, run social ads, send email announcements, and create educational content.
11. Establish a reorder rhythm — review sell-through data monthly and adjust your assortment based on what moves.
12. Stay connected to your supplier — join inventory broadcast channels (like WhatsApp updates) and keep communication lines open for trend insights and new arrivals.

Frequently Asked Questions

What certifications should lab-grown diamonds have?

Every lab-grown diamond you sell should carry certification from a recognized independent gemological laboratory — most commonly the International Gemological Institute (IGI) or the Gemological Institute of America (GIA). These certifications verify the diamond's 4Cs (cut, color, clarity, and carat weight) and confirm it is laboratory-grown. Certified stones build customer confidence and protect your store's reputation.

How much cheaper are lab-grown diamonds compared to natural diamonds?

Lab-grown diamonds are typically 70–80% less expensive than comparable natural diamonds. As of 2025, a 1-carat lab-grown diamond averages $1,000 or less at retail, compared to approximately $4,200 for a natural 1-carat diamond. This price advantage allows your customers to purchase significantly larger or higher-quality stones within the same budget.

How do I explain lab-grown diamonds to customers who are skeptical?

Be transparent and factual. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — they are real diamonds. They're graded using the same 4Cs criteria and certified by the same laboratories. The primary differences are origin (laboratory vs. earth) and price. Most skepticism dissolves when customers see certification side-by-side and understand that even gemological experts cannot distinguish them without specialized equipment.

Can I sell lab-grown and natural diamonds in the same store?

Absolutely, and most successful retailers do. Offering both gives your customers the power to choose based on their own priorities — whether that's budget, size, sentiment, or values. The key is to present both options honestly, without steering. Make sure your signage clearly identifies which diamonds are lab-grown and which are natural, as required by FTC guidelines.
