Guru Diam is a trade-only wholesaler and manufacturer in New York and Los Angeles. We supply verified resellers (live-selling app sellers, Instagram brands and Shopify or Etsy stores) with certified lab-grown diamond jewelry, with no minimum order and same-day shipping.

Who This Lab-Grown Jewelry Wholesale Program Is For
Online and live resale has become a real channel for fine jewelry. It needs a different supplier setup from a traditional store. We work with these reseller types:
- Live-auction sellers who run jewelry shows and need a steady flow of certified pieces to show on camera, with fast shipping once the auction closes.
- Social commerce and Instagram Live sellers who sell in short bursts and can't hold a large inventory of each style.
- Shopify, Etsy and own-site brands who list pieces online and want the supplier to ship straight to the end customer.
- Independent jewelers selling online who use live video or social selling alongside the store counter.
- New private-label brands who want their own designs made without a large first production run.
What they have in common: they sell before they buy, they need certificates the buyer can verify, and they can't afford slow fulfilment. A missed ship date shows up as a bad review the same week.
Why Lab-Grown Diamond Jewelry Works for Live Selling
Lab-grown diamonds are real diamonds. They have the same crystal structure, hardness and optical behavior as mined diamonds, and the difference is where they were made. For a reseller, that brings three practical advantages.
Bigger looks at a price live audiences accept. A pair of 2 ct total weight studs or a 5 ct tennis bracelet is within reach in lab-grown. Those are the pieces that stop the scroll on a live show.
A certificate the buyer can check. Larger lab-grown pieces come with an IGI report the buyer can verify online. Holding the certificate to the camera does more for trust than any description.
Repeatable inventory. Lab-grown diamonds are produced to spec, so the bestseller from last week can be restocked in the same quality. That matters when your audience asks for "the same one you showed on Tuesday."
Disclose lab-grown clearly. The US Federal Trade Commission's Jewelry Guides require lab-grown diamonds to be described as lab-grown, laboratory-created or similar, every time. Put it in the listing title, say it on camera and keep it on the invoice.
What to Look for in a Lab-Grown Jewelry Dropshipping Supplier in the USA
Many dropshipping suppliers are catalog resellers who ship from overseas factories. Before you list a single piece, check each supplier against this list:
| Check | Why it matters for a reseller | Guru Diam |
|---|---|---|
| US stock and US shipping | Live buyers expect their order in days, not weeks | Stock in New York and Los Angeles; same-day shipping from New York before 6 PM ET |
| Blind or white-label shipping | Your customer should see your brand, not your supplier's | Yes, for trade accounts |
| Minimum order | MOQs force you to buy before you know what sells | None |
| Certification | Buyers ask "is it real?" on every show | IGI on jewelry; 10,000+ IGI/GIA-certified loose diamonds |
| Stated diamond quality | Vague quality claims lead to returns | D–F color, VVS–VS clarity in jewelry |
| Solid gold or platinum, not plated | Plated pieces lead to complaints and chargebacks | 14K/18K gold and platinum; findings in solid gold of the piece's karat |
| Inventory feed | Stops you selling a piece that's already gone | API and CSV feed integration |
| A real person to call | Problems on show night need answers that night | Dedicated account manager for each trade account |
| Return policy | Your return policy can only be as good as your supplier's | 14-day free return on stock items |
If a supplier can't answer every row in writing, you will end up answering those questions for them in front of your buyers.
Drop-Shipping vs Holding Stock: Which Model Fits a Live Seller?
Most resellers end up using both. Here is how the three models compare:
| Model | How it works | Best for | Watch out for |
|---|---|---|---|
| Blind drop-ship | You sell first, place the order, and we ship to your customer with no Guru Diam branding or pricing | Online stores, testing new styles, higher-ticket pieces you don't want sitting in a safe | Your listing must stay in sync with our stock (use the feed) |
| Hold a show inventory | You buy a selection and show the real pieces on camera | Live shows, where buyers want to see the exact piece | Cash tied up in stock; choose bestsellers |
| Made to order / private label | We make your own design from a 3D CAD | Signature pieces and your own brand | Lead time of 4–6 working days after you approve the CAD (rush: guaranteed 4 days at extra charge) |
A common setup: hold a small show inventory of bestsellers such as studs, a tennis bracelet and a few solitaires, drop-ship everything else, and add one or two private-label signature pieces once your audience is established. Our longer guide to lab-grown diamond drop-shipping and blind shipping goes through the order flow step by step.
What Resellers Buy Most: Lab-Grown Studs, Tennis Bracelets and Rings
These categories sell best on live shows and online stores, along with what we keep in stock for each:
- Stud earrings. All shapes, up to 10 ct total weight in stock, with push-back or screw-back backs. Studs of about 2 ct total weight and up come IGI-certified. See matched diamond pairs for stud earrings.
- Tennis bracelets and necklaces. All shapes. Bracelets run 2–32 ct total weight, with the 7-inch standard size always in stock and other lengths made to order. Necklaces are 17 inches standard and 16–22 inches made to order.
- Engagement rings and solitaires. Ring size 7 is stocked as standard. Larger center diamonds come IGI-certified. Mountings and semi-mounts are available if you set your own centers. See wholesale engagement rings.

How Blind Drop-Shipping Works With Guru Diam
- Get approved. Apply for a trade account. Applications submitted before 4 PM ET are reviewed the same business day.
- Connect your inventory. Use the API or CSV feed so your store lists only what is actually available, or work from our live site while logged in.
- Sell first. Your customer buys from your show, store or listing at your price.
- Place the order with us. Send the item, the end customer's shipping address and the request for blind shipping. Your account manager confirms it.
- We ship. Orders placed before 6 PM ET leave New York the same day. The package carries no Guru Diam branding or pricing.
- Your customer receives your sale. If the piece needs to come back, our 14-day free return on stock items gives you room to honor your own policy.
Keep Listings Accurate With an API or CSV Inventory Feed
Selling a piece you no longer have is the fastest way to lose a live audience's trust. Trade partners can connect to our inventory through an API or a CSV feed. Your store or listing tool then shows only what we have in stock, along with the details you need: shape, carat weight, color, clarity, metal and certificate number. If you sell on several channels, one feed can update all of them.
Private Label and Custom Pieces for Your Brand
Once you know what your audience buys, your own designs are what set you apart from every other seller with the same catalog. We offer private label: you send a sketch or a reference photo, and we send back a 3D CAD in 24 hours. The finished piece follows in 4–6 working days after you approve the CAD. Complex pieces can take 2–3 weeks. Rush service guarantees delivery in 4 days, at an extra charge. There is no minimum order, so one piece is enough to test a design on a show before you commit to more. Read more on custom jewelry manufacturing for jewelers and brands.
Lab-Grown Diamonds vs Moissanite vs Natural Diamonds for Resellers
Live audiences ask about the difference every show. A reseller who can explain it in one sentence closes more sales and handles fewer returns.
| Lab-grown diamond | Natural diamond | Moissanite | |
|---|---|---|---|
| What it is | Real diamond (carbon), grown in a lab | Real diamond (carbon), mined | Silicon carbide; a different gemstone, not a diamond |
| Can it be called a diamond? | Yes, with the "lab-grown" disclosure | Yes | No |
| Grading report | IGI (GCAL also available at Guru Diam) | GIA or IGI | Usually none from a diamond lab |
| Look on camera | Same fire and brilliance as natural | The benchmark | Stronger rainbow flashes, easy to spot side by side |
| Price position | Big looks at an accessible price | Highest per carat | Lowest |
For most live sellers, lab-grown is the sweet spot. Buyers get a real, certified diamond at a size they can afford, and the seller gets a product that holds up when someone checks the certificate. We supply natural diamonds as well, if your audience asks for them.
Understanding Diamond Certificates When You Resell
A certificate (grading report) is the strongest trust signal you can show a buyer you have never met. Here is what resellers need to know:
- IGI grades most lab-grown diamonds sold in the US. Each report has a number the buyer can look up on IGI's website.
- GCAL is offered for lab-grown diamonds at Guru Diam as an alternative report.
- GIA is the long-standing reference for natural diamonds. Our loose inventory includes GIA-certified diamonds.
- What's on the report: carat weight, color, clarity, cut (for rounds), measurements, and for lab-grown, a statement that the diamond is laboratory-grown. Many reports also note the growth method (mostly CVD, some HPHT in our range).
- Which pieces carry one: larger diamonds. Studs of about 2 ct total weight and up, and larger engagement ring center diamonds, come IGI-certified. Small accent diamonds (melee) are not individually certified anywhere in the industry.
Show the report on camera, print the number on the listing, and keep a copy with the order. If a buyer ever questions a piece, the report number settles it.
Pricing Lab-Grown Jewelry for Live Shows and Online Stores
We don't set your retail prices, but these are the habits we see in resellers who keep coming back to restock:
- Price from your landed cost. Add our trade price, shipping, platform fees (each live-selling app and Shopify takes its own cut), packaging and an allowance for returns. Then set your margin.
- Keep a ladder of price points. Small studs and pendants as entry pieces, tennis bracelets and larger studs in the middle, and solitaires as the headline piece of the show.
- Don't race to the bottom on certified pieces. A certified 2 ct pair is a different product from an uncertified "2 ct look". Make the difference clear on camera and price for it.
- Use starting bids carefully. On auction-style shows, set starting bids you can live with. Your cost is fixed even when the final bid isn't.
Payment and Trade Terms for Resellers
- Payment methods: wire, ACH, check and debit card. We do not accept credit cards.
- Credit and memo terms: available for established, approved accounts.
- Pricing: trade prices show once you are logged in. Lab-grown loose diamonds start from $75/ct for rounds. Jewelry is priced per piece.
- Account manager: every trade account gets a dedicated contact.
Running a Live-Selling Show With Wholesale Inventory
Experienced live sellers tend to follow the same few practices:
- Show the certificate. Hold the IGI report up to the camera and read out the report number. Buyers check it.
- Say "lab-grown" every time. Put it in the title, say it on air and print it on the packing slip. That's an FTC requirement, and it also cuts down on returns.
- Start with a few styles in depth. Studs in three sizes, one tennis bracelet in two carat weights, and two or three solitaires usually do better than one of everything.
- Know your shipping promise. If you drop-ship, the ship date depends on ours: same day from New York on orders before 6 PM ET. Promise what both of us can keep.
- Restock fast. When a piece sells out on Tuesday, reorder the same spec that day so it's ready for the next show.
- Match your return policy to ours. Our 14-day free return on stock items lets you offer a clear return window without taking on all the risk.
Common Mistakes New Jewelry Resellers Make
Most resellers who give up on fine jewelry make the same few mistakes in their first months. All of them can be avoided:
- Buying deep before testing. Ordering 20 of one style before a single show ties up cash in pieces that may not sell. With no minimum order, test one or two pieces of a style on air first, then reorder what sells.
- Vague product descriptions. "Diamond ring" isn't enough. List the metal and karat, the total carat weight, the color and clarity range, and the word "lab-grown". Clear descriptions cut returns.
- Listing pieces you can't confirm. If your listings aren't connected to your supplier's live stock, you will sell something that's already gone. Use a feed, or check with your account manager before a big show.
- Ignoring ring sizes. Rings sell in a standard size 7. Tell buyers how resizing works before they bid, not after. Resizing is part of our after-sales service.
- Treating every channel the same. A live auction, a social shop listing and a Shopify product page need different photos, price points and shipping promises. The same piece can work on all three, presented differently on each.
- Working with a supplier you can't reach. When a buyer asks a question mid-show, you need an answer fast. A dedicated account manager is worth more than a slightly lower price from a supplier who replies two days later.
Why US-Based Supply Matters for Online Jewelry Resale
Overseas factory dropshipping works for low-cost fashion jewelry. It's a poor fit for certified fine jewelry sold on live video. Shipping times run long, it's hard to verify quality before the piece reaches your customer, and returns cross an ocean. A US wholesaler with stock in New York and Los Angeles ships fast, can confirm the piece and its certificate before it leaves, and handles returns and repairs domestically. For resellers outside the US, international delivery from New York takes 3–4 business days.
How to Get Approved as a Reseller

To apply, fill in the trade partner application with your business details and where you sell (live-selling apps, Instagram, your own site). Applications submitted before 4 PM ET are approved the same business day. You can also visit our showrooms in New York (Diamond District) or Los Angeles by appointment.
