Lab Grown Diamonds
How to Sell Lab-Grown Diamonds: The Wholesale Reseller's Guide
61% of engagement ring center stones. 60–75% margins. The majority of the diamond market — here's everything you need to source and sell it.
Lab-grown diamonds now account for 61% of all engagement ring center stones sold in 2026, up from 52% just two years ago. For jewelry resellers, that shift represents one of the clearest opportunities in the wholesale market right now: a product your end consumers are actively seeking, at margins that outperform natural diamonds, available with a low minimum order.
You already know that this business runs on margin and on reading your customers. Right now, a large portion of buyers at every price point are asking about lab-grown diamonds. Whether you run a boutique, a swap meet booth, or an e-commerce store, this category is worth understanding — because the resellers who understand it are outselling those who don't.
This guide covers exactly how to stock, price, and sell lab-grown diamond jewelry: what they are, why they're moving, what margins to expect, how to have the customer conversation, and how to source them wholesale.

What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds. Not simulants, not fakes — real diamonds, made of pure carbon with the same crystal structure, the same hardness (10 on the Mohs scale), and the same optical properties as mined stones.
The only difference is origin. Mined diamonds formed underground over billions of years under extreme pressure and heat. Lab-grown diamonds are created in a controlled environment that replicates those same conditions — in weeks instead of millennia.
The GRA (Gem Research Swisslab) certifies lab-grown diamonds using the same grading standards applied to mined stones: cut, color, clarity, and carat weight. Every certified stone has its report number and a lab-grown designation laser-inscribed on the girdle.
CVD vs. HPHT: What Resellers Need to Know
Two production methods dominate the market. HPHT (High Pressure High Temperature) subjects carbon to intense pressure and heat in a process that mimics natural diamond formation. CVD (Chemical Vapor Deposition) grows diamonds layer by layer inside a chamber filled with carbon-rich gas.
As a reseller, you don't need to memorize the chemistry. Both methods produce certified, real diamonds. Customers rarely ask which process was used — and when they do, a straightforward answer handles it: "Our lab-grown diamonds are GRA certified real diamonds, grown in a controlled environment instead of mined."
- Real diamonds — same carbon, same hardness (10 Mohs), same optical properties as mined stones
- GRA certified — graded on the same 4Cs scale as natural diamonds; report number laser-inscribed on the girdle
- Visually identical — a jeweler's loupe cannot distinguish lab-grown from mined; only specialized equipment can detect origin
- 73% lower cost — at wholesale, enabling margins your natural diamond inventory can't match

The numbers behind this shift are not marginal. According to The Knot's 2026 Real Weddings Study, lab-grown diamonds now represent 61% of all engagement ring center stones — up from 52% just two years ago. Two-thirds of Gen Z buyers prefer lab-grown when given the choice.
The global lab-grown diamond market was valued at $29.73 billion in 2025 and is projected to reach $108.98 billion by 2035, growing at a 13.87% compound annual rate.
The Price Gap Is Driving Customer Demand
A 1-carat natural diamond in G color, VS2 clarity retails for $4,000–$6,000. The same specifications in a lab-grown stone retail for $750–$1,500. That is a 73% price difference for a diamond your customers cannot visually distinguish from the mined version.
The practical impact on buying behavior is significant. The average lab-grown engagement ring center stone has grown to 2.45 carats in 2026, compared to 1.16 carats for natural diamond rings. Your customers' buyers want bigger, better-looking diamonds. Lab-grown gets them there at a price they can say yes to.
Gen Z and Millennials Are Already Asking for Them
These buyers came of age knowing lab-grown diamonds exist. Many specifically want lab-grown because of the price and because of where mining sits in their value system. They're not reluctant converts — they're your most motivated buyers in this category. When a 28-year-old walks into your store and asks about lab-grown diamonds, she's already done her research. Your job is to be the reseller who has them.
The Margin Opportunity: What Resellers Can Expect
Retail gross margins on lab-grown diamond jewelry run 60–75%, compared to 40–45% on natural diamonds. The nuance is that because the retail price is lower, the absolute dollar profit per sale is smaller. A 65% margin on a $1,400 ring nets you $910 gross profit. A 42% margin on a $5,000 natural diamond ring nets you $2,100.
Lab-grown diamonds are not a replacement for natural diamond sales — they are an addition. They serve a lower price point, reach more customers, and move faster. Think of them as high-margin, high-velocity inventory for buyers who want diamond quality without the natural diamond price tag.
- Lower material cost, high perceived value — Lab-created production keeps wholesale pricing predictable. Retail value is driven by the diamond's visual presence and certification, not commodity scarcity.
- Size advantage closes sales — A customer at a $1,500 budget gets a 2-carat certified lab diamond vs. a 0.75-carat natural. That visual difference does the selling for you.
- Upsell dynamics — Customers who come in for sterling silver often leave with a lab-grown diamond piece once they see what's possible at their budget. Lab-grown raises your average ticket without a separate sales effort.
Which Lab-Grown Jewelry Styles Sell Best
Not all lab-grown diamond jewelry moves equally in retail. Here's where the volume is:
Engagement-Style Rings
The highest-demand category by far. Center stone rings in prong and halo settings are the primary driver of the category. Round brilliant, oval, and cushion cuts are the strongest shapes. Customers who come in for engagement pieces are the most motivated buyers and the highest average ticket in the store.
- Round brilliant solitaires in prong settings (1ct, 1.5ct, 2ct equivalent)
- Oval lab-grown — fastest-growing shape in 2026, following the same trend as in natural diamonds
- Halo settings for customers who want maximum visual presence at a given carat weight
Tennis Bracelets and Necklaces
Classic styles with channel-set or prong-set lab-grown stones are strong year-round performers. Tennis pieces benefit from the broader tennis jewelry trend that has driven sales across all gemstone types. Higher price points and strong perceived value make them excellent for boutiques.
Stud Earrings
Entry-level price points, easy sell, consistent replenishment cycle. Studs are the gateway purchase for customers curious about lab-grown diamonds. Once they own a pair and understand the product, they come back for larger pieces.
Solitaire and Halo Pendants
Mid-range price points with strong movement for boutiques and e-commerce. Fashion styles with smaller individual stones (0.10–0.25 carat per stone) perform particularly well for sellers who want diamond pieces at accessible retail prices.
How to Talk to Your Customers About Lab-Grown Diamonds
This is where most resellers feel uncertain at first. The conversations become straightforward once you've had them a few times.
The Lab-Grown vs. Natural Conversation
When a customer asks how lab-grown compares to natural, be direct. Lead with what's the same, then explain the difference:
- Lead with "real diamonds" — Lab-grown diamonds are GRA certified real diamonds. Same material, same hardness, same grading. Don't let the conversation start with "it's not mined."
- Show the size they get at budget — Put a 2-carat lab-grown and a 0.75-carat natural side by side at the same price. That visual closes more sales than any explanation.
- Address resale value honestly — Lab-grown diamonds typically resell for 20–40% of purchase price vs. 20–60% for natural. Natural diamonds hold better resale value. Say it plainly — then follow with: most people never sell their jewelry. The value is in wearing it.
- Use simple language that works — "More diamond for your money." "GRA certified real diamonds, grown in a lab." "Same carbon, same hardness, same look — different origin."
Lab-Grown vs. Moissanite: Know the Difference
| Factor | Lab-Grown Diamond | Moissanite |
|---|---|---|
| Material | Pure carbon — identical to mined diamond | Silicon carbide — a distinct gemstone |
| Refractive Index | 2.42 — identical to mined diamond | 2.65 — more fire & brilliance |
| Certification | GRA grading report (4Cs) | Brand or supplier quality documentation |
| Wholesale Cost | Higher than moissanite, lower than mined | Significantly lower per carat |
| Best Selling To | Diamond-focused, engagement, milestone buyers | Value-conscious, trend-forward, hip hop segment |
| Retail Margins | 60–75% | 60–75% |
The smart retail strategy: carry both. They serve different buying occasions and different customers — they don't compete the way resellers sometimes assume.
Silver Palace carries both wholesale lab-grown diamonds (GRA certified) and moissanite jewelry — so you can source both categories from one supplier relationship.

Not every wholesale supplier is the same. Here's what matters when you're evaluating where to buy.
Ready Stock
Lab-grown diamond prices have shifted significantly over the last several years. You want a supplier who has inventory on hand — not one who drop-ships or sources to order. Ready stock means you know what you're getting, when it ships, and at what price.
Low Minimums
When you're testing a new category, you shouldn't have to commit thousands of dollars upfront. A $200 minimum lets you place a real test order and learn what moves in your market before scaling.
Certification Standards
Source lab-grown diamond jewelry certified by GRA (Gem Research Swisslab). GRA certifies lab-grown diamonds using the same 4Cs grading criteria applied to mined stones — cut, color, clarity, and carat weight. Every certified stone has its report number and lab-grown designation laser-inscribed on the girdle, invisible to the naked eye and verifiable under magnification.
Do not source uncertified stones for anything you're representing as a diamond. Certification is the confidence signal that closes sales with discerning buyers and protects you as a reseller.
Category Breadth and Experience
The best wholesale relationships are ones where you can source multiple product lines from one supplier. Carrying lab-grown diamonds alongside wholesale sterling silver, moissanite, and Italian chains under one roof simplifies sourcing and your vendor relationships.
Silver Palace has supplied jewelry resellers from our LA Jewelry District showroom for over 30 years. Lab-grown diamond jewelry available with a $200 minimum, same-day shipping from ready stock, and the option to walk in at 640 S. Hill St. to see product in person before you order.

Frequently Asked Questions
Are lab-grown diamonds considered real diamonds?
Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. GRA certifies them using the same grading standards. They are not simulants like cubic zirconia or moissanite — they are real diamonds.
Do I need a special license to sell lab-grown diamonds?
No special license beyond what you already hold for selling jewelry. FTC guidelines require disclosure when a diamond is lab-grown — you cannot represent it as a mined stone without saying so. Being upfront is both legally required and better for sales.
How much can I mark up lab-grown diamond jewelry?
Retail gross margins typically run 60–75%. Where you land depends on your market, location, and customer base. Start at the lower end of the range while you learn what your customers will pay, then adjust based on what you're seeing.
Are lab-grown diamond prices stable right now?
Wholesale prices have declined significantly since 2018 — roughly 87% overall — as production has scaled up. The market appears to be approaching a floor near actual production costs. For resellers buying at current wholesale rates and selling at current retail, the margin picture is favorable.
How do lab-grown diamonds compare to moissanite?
Lab-grown diamonds and moissanite serve different customers. Moissanite is a distinct gemstone (silicon carbide) with its own optical properties — more fire and brilliance, at a lower price point than lab-grown. Some resellers carry both: moissanite for the entry-level price point, lab-grown for customers who specifically want a diamond. They're complementary, not competing.
The Bottom Line for Resellers
This is not a niche. Lab-grown diamonds are now the majority of the diamond jewelry market, and the growth is not slowing. Resellers who carry lab-grown diamond jewelry are reaching customers they couldn't reach before — buyers who want certified diamond quality at a price that works for their budget.
The margin structure is solid. The customer demand is real. The product knowledge required to sell confidently is straightforward to build. The main barrier is inertia — not starting because you haven't started.
Start with a small test. Pick a handful of styles, learn what moves in your market, and build from there. At a $200 minimum with same-day shipping, you're not making a large bet. You're making a smart one.
