Book Appointment
Opening a wholesale lab-grown diamond account gives a jeweler direct trade pricing, access to certified loose inventory, and made-to-order cutting from one relationship. Approved jewelers, designers, and retailers contact the supplier's Diamond District office to set up terms, then order single certified center stones, bulk melee, matched pairs, and custom layouts from a single trade account.
Who qualifies as trade for a wholesale account?
Trade accounts are for working businesses in the jewelry industry: independent jewelers, custom designers, and retailers who buy diamonds to set or resell, not for the general public. Guru Diam is a trade-only manufacturer, so an account is verified as a business relationship before pricing is shared.
In practice, that means anyone who sells finished jewelry, takes custom orders at a bench, or stocks a retail case is the kind of buyer a wholesale account is built for. The verification step exists because direct manufacturer pricing on loose stones is fundamentally different from the consumer pricing a walk-in shopper sees. A trade account is the mechanism that separates the two: it confirms you are buying to build or resell, which is what unlocks pricing at the source instead of pricing layered with retail markup.
You do not need to be a large operation to qualify. A solo designer taking a handful of custom commissions a year and a multi-location retailer both fit the trade-only model. What matters is that you are a legitimate business in the trade, with the details on hand to set the account up. To confirm whether your business fits, contact the Diamond District office directly rather than assuming a threshold either way.
What does a wholesale account actually unlock?
A wholesale account unlocks direct manufacturer pricing, the full loose-stone inventory, and custom cutting, all through one point of contact. Instead of buying finished or pre-mounted goods at retail, you buy loose IGI-certified stones by spec and carry the margin a retail layer would otherwise take.
The most practical benefit is breadth from a single relationship. The same account spans certified center stones for focal points, calibrated melee for pavé and accents, matched pairs for studs and drops, antique cuts in old mine and old European style for vintage-inspired work, and fancy colors for statement pieces. With 10,000+ loose stones in inventory, a jeweler can fill an entire design from one desk rather than stitching a single ring together across several vendors and reconciling separate paperwork. Certification is standard: IGI on loose stones, with GIA available on request when a client or design brief requires it. Anything outside the in-stock range is handled through custom, made-to-order cutting from in-house CVD production. The table below summarizes what the account opens up.
| What the account unlocks | What it means for the bench |
|---|---|
| Direct manufacturer pricing | Loose stones quoted at the source, without a retail markup layered on |
| Full loose inventory (10,000+ stones) | Centers, calibrated melee, matched pairs, antique cuts, and fancy colors from one desk |
| IGI certification standard | Documented, independent grading on loose stones; GIA on request |
| Made-to-order cutting | Sizes and proportions not in stock cut to spec from in-house CVD production |
| One trade relationship | Quote, confirm, and source across categories without juggling multiple vendors |
Single stone, bulk melee, or custom: which order type fits?
A trade account supports all three order types interchangeably, so you choose by what the design needs rather than by what an account allows. A single certified center stone suits one-off custom rings, bulk calibrated melee suits stock and repeat pavé work, and custom cutting suits specs that are not on the shelf.
Most working benches use a mix. A custom engagement commission might pull one certified center stone plus a parcel of calibrated melee for the halo. A retailer keeping a case stocked might order matched pairs for studs and melee by shape and size to have on hand. A designer whose layout calls for an unusual proportion routes that piece through made-to-order cutting while sourcing the surrounding accents from in-stock inventory. Because all three flow through the same account, you are not opening separate relationships for each pattern. The table below maps the three order types to the jobs they fit best.
| Order type | Best fit | How it sources |
|---|---|---|
| Single certified stone | One-off custom rings, three-stone designs, focal pendants | Selected by spec from in-stock centers; IGI standard, GIA on request |
| Bulk melee | Pavé, halos, channel work, stock for repeat designs | Calibrated melee by shape and size from loose inventory |
| Custom layout | Sizes or proportions not currently in stock | Made-to-order cutting from in-house CVD production |
How do you get set up with a trade account?
You get set up by reaching out to the Diamond District office as a verified business and providing your trade details, then placing a first order by spec once the account is active. The first order typically starts with one design's requirements rather than a bulk commitment.
The entry point is a phone call to the NYC desk at (212) 652-7108 or a visit to the office at 36 West 47th Street, Suite 601A, New York, NY 10036. West Coast buyers can use the LA office at 607 South Hill Street, Suite #241, Los Angeles, CA 90014. Have your business details ready so the trade-only account can be confirmed and set up. Account specifics such as terms are handled directly with the office rather than assumed in advance, so the office is the right place to confirm how setup works for your business.
Once the account is active, bring the design's requirements to the desk: the center-stone spec, any melee shapes and sizes, whether you need matched pairs, and whether the piece calls for antique cuts or fancy colors. The team checks those needs against the 10,000+ loose stones in inventory and flags anything that should be cut to spec. From there you can quote, confirm, and source loose certified stones for the build. When you are ready to open a trade account, the office handles verification and walks you through your first order.
Why open the account with a Diamond District manufacturer?
Opening the account with a manufacturer rather than a reseller shortens the distance between your order and a finished, certified stone. In NYC's Diamond District, manufacturing, certification handling, and trade sales sit close together, so a jeweler moves from spec to certified loose stone without routing the order through layers of intermediaries.
Guru Diam runs in-house CVD production behind the inventory, which means the supply line a trade account taps into is the same one the stones come off of. That proximity matters most on custom work: when a design needs a size or proportion that is not on the shelf, made-to-order cutting happens against the same operation that produces the stock inventory, so the custom path and the in-stock path draw from one source rather than two. For a jeweler, that translates into one relationship that covers in-stock selection, certification, and custom cutting, instead of a chain of resellers each adding a step. The Diamond District location keeps that whole loop within a few blocks of the trade.
Frequently asked questions
Who can open a wholesale lab-grown diamond account?
Jewelers, designers, and retailers who buy diamonds to set or resell can open an account. Guru Diam is a trade-only manufacturer, so accounts are for verified businesses in the jewelry trade rather than the general public. To confirm whether your business qualifies, contact the Diamond District office directly.
What do I need to set up a trade account?
You set up an account by contacting the NYC office at (212) 652-7108 or the LA office and providing your business details so the trade-only relationship can be verified. Account specifics such as terms are handled directly with the office, so reach out to confirm exactly how setup works for your business.
Can I order a single stone, or do I have to buy in bulk?
You can order a single certified center stone for one custom design, a parcel of calibrated melee, or both through the same account. The first order typically starts with one design's requirements rather than a bulk commitment, and all order types flow through the same trade relationship.
Are the diamonds certified?
Yes. Loose stones come IGI-certified as the standard, and GIA certification is available on request when a client or design brief calls for it. Buying loose keeps each diamond and its certificate together and independent, so you can verify the grading before any stone is set into a piece.
What if the size or cut I need isn't in stock?
Guru Diam offers custom, made-to-order cutting for sizes and proportions not currently in inventory. Production is handled in-house through CVD, so a spec that is not on the shelf can be cut to order against the same operation that supplies the 10,000+ loose stones already in stock.
Where do I open the account?
The NYC office is at 36 West 47th Street, Suite 601A, New York, NY 10036, reachable at (212) 652-7108, in the Diamond District. West Coast trade buyers can use the LA office at 607 South Hill Street, Suite #241, Los Angeles, CA 90014. Both serve trade buyers opening wholesale accounts.
