Guru Diam is a trade-only diamond wholesaler that supplies Canadian jewellers, retailers, designers and manufacturers from New York. We stock 10,000+ IGI and GIA certified diamonds, natural and lab-grown, plus calibrated melee, matched pairs, fancy colours, antique cuts and finished fine jewellery. We also manufacture custom jewellery with a 24-hour CAD and no minimum order. Orders placed before 6 PM Eastern ship the same day from New York, and delivery to Canada typically takes 3–4 business days. Trade accounts submitted before 4 PM Eastern are approved the same business day.
This page is written for the trade: jewellery stores in Toronto, Vancouver, Calgary, Montreal and across Canada, bench jewellers who need calibrated melee for a tennis bracelet this week, and designers who want one supplier for the centre diamond, the side diamonds and the finished piece. If you are a consumer looking for an engagement ring, we are not the right fit: we sell only to verified jewellery businesses.
Below you will find what we supply, how shipping to Canada works, how to open a trade account, how payment and returns work, and the questions Canadian buyers ask us most often. If you already know what you need, you can open a trade account now and an account manager will contact you the same business day.

Why Canadian Jewellers Work With a New York Diamond Wholesaler
Most Canadian jewellery stores already buy from more than one supplier. A local wholesaler covers the everyday needs, a manufacturer handles casting, and a third source fills the gaps when a client asks for a specific shape, a matched pair or a fancy colour that nobody in town has in stock. Every extra supplier means another account, another invoice and another delay.
Guru Diam puts those jobs in one place. We are based at 36 West 47th Street in the New York Diamond District, one of the deepest diamond markets in the world, and we hold a large certified inventory on hand rather than listing diamonds we would have to find first. For a Canadian jeweller, that means three practical things:
- Depth of choice. 10,000+ certified diamonds across shapes, sizes and grades, so the diamond your client asked for is more likely to be in stock today.
- Speed. Same-day dispatch from New York on orders placed before 6 PM Eastern, with delivery to Canada typically in 3–4 business days.
- One supplier for the whole piece. The centre diamond, the matched side diamonds, the calibrated melee and the finished setting can all come from the same account.
Toronto and Montreal share our time zone, so a jeweller in either city can call or message us during the same working day and still make the 6 PM cut-off. For Vancouver and Calgary, the cut-off falls in the early afternoon local time (3 PM in Vancouver, 4 PM in Calgary), which still leaves most of the business day to confirm an order.
Certified Lab-Grown Diamonds Wholesale for Canada
Lab-grown diamonds are now a standard part of most Canadian bridal and fashion counters, and the questions buyers ask have shifted from "should we carry them?" to "who can supply them consistently?". We stock lab-grown diamonds in all popular shapes and sizes, graded by IGI, and GCAL certification is also available on lab-grown diamonds.
Our lab-grown production is mostly CVD, with some HPHT. Every certified diamond is listed with its report, so you can check the grading before you buy. When a client asks for something specific that is not in stock, we can source it, or cut a diamond to your specification.
Typical lab-grown requests from Canadian jewellers include:
- 1–3 carat round, oval, emerald and radiant centre diamonds for engagement rings
- Elongated shapes in specific length-to-width ratios
- Larger certified centres for statement pieces
- Lab-grown diamonds in fancy colours for fashion jewellery
Browse the full range on our lab-grown diamonds page, or read our guide to sourcing GIA and IGI certified lab-grown diamonds wholesale.
Natural diamonds for Canadian buyers
We also carry natural diamonds, certified and melee, for jewellers whose clients ask for them. Natural diamonds are on our certified natural diamonds page, and natural melee is listed under natural melee. Natural matched pairs are made to order.
Calibrated Melee Diamonds Wholesale
Melee is where a lot of jewellery work stalls. A pavé band, a halo or a tennis bracelet only looks right when every small diamond is the same size and the same colour, and many parcels arrive with too much spread. Our melee is calibrated to ±0.05–0.10 mm, so diamonds sit evenly in a setting and the setter spends less time sorting.
Our lab-grown melee is CVD Type IIa. We sell by size, so you can order the exact millimetre sizes a design calls for rather than a mixed parcel. For pavé, eternity bands, halos, cluster settings and tennis pieces, calibrated melee saves bench time and reduces waste.
See sizes and availability on the wholesale melee page, or read our guide to calibrated melee for pavé, tennis and eternity work.
Matched Pairs for Earrings and Three-Stone Rings
Matching two diamonds by eye is slow, and a pair that looks right on the tray can look uneven once it is set. Our matched pairs are matched to ±0.1–0.2 mm in size and within about one colour grade, so stud earrings and three-stone side diamonds look balanced on the client.
Lab-grown matched pairs are available in all shapes. Natural matched pairs are made to order. If you need a pair to sit beside a centre diamond you already have, send us the centre's measurements and we will match the side diamonds to it.
Fancy Colour and Antique-Cut Diamonds
Canadian clients increasingly ask for something that does not look like every other ring in the case. We carry fancy colour diamonds in seven colours: black, blue, brown, green, pink, red and yellow. We also carry so many antique and old cuts, including Old Mine and Old European cut diamonds, for vintage-style and heritage pieces.
See the range on our antique and fancy colour wholesale page, or read about antique-cut lab-grown diamonds wholesale.
Wholesale Jewellery for Canadian Retailers
Alongside loose diamonds, we keep 3,000+ finished jewellery pieces in stock, ready to ship. Diamond quality in our jewellery is D–F colour and VVS–VS clarity, with IGI certification. Popular lines for Canadian stores include:
| Category | What we stock |
|---|---|
| Tennis bracelets | 2–32 ct total weight; 7-inch standard size always in stock; other lengths made to order |
| Tennis necklaces | 17-inch standard; 16–22 inches made to order |
| Stud earrings | All shapes, up to 10 ct total weight in stock; push-back and screw-back; 2 ct total weight and up come IGI certified |
| Engagement rings | Solitaire, three-stone and halo styles; standard size 7 in stock |
| Mountings and semi-mounts | Available without a centre diamond, ready for your own centre |
| Eternity and wedding bands | Full and partial eternity bands in 14K and 18K gold and platinum |
Metals are 14K and 18K gold in yellow, white and rose, and platinum. White gold is always rhodium plated, and the default finish is high polish. Findings such as posts, backs and clasps are solid gold in the piece's karat. Browse everything on the wholesale jewellery page.
Custom Jewellery Manufacturer for Canadian Jewellers
Many Canadian jewellers do not have a full bench in-house, or have one that is already booked solid. Our custom jewellery service acts as your bench: you keep the client relationship and the margin, and we build the piece.
Here is how it works:
- Send the spec. A sketch, a photo or a written description is enough: piece type, metal, centre diamond and size.
- Approve the 3D CAD. We send a CAD render within 24 hours. Nothing is cast until you approve it.
- We cast, set and finish. Production is in-house in New York and India. The diamonds come from our own inventory.
- Delivery. The finished piece is ready 4–6 working days after CAD approval. Complex pieces may take 2–3 weeks. Then it ships to you in Canada, typically in 3–4 business days.
There is no minimum order: one piece is an order, paid per piece. If a client is waiting, rush service guarantees delivery in 4 days for an extra charge. We also offer private label production, engraving, satin, matte and hammered finishes on request, and after-sales service such as resizing and repairs.
For a deeper look at the process, read our wholesale custom jewellery manufacturer guide or how much custom jewellery costs wholesale.
Shipping Diamonds and Jewellery to Canada
Speed is the main reason Canadian jewellers choose a supplier in New York over one further away. Here is what to expect:
| Step | Timing |
|---|---|
| Order cut-off | 6 PM Eastern (Toronto and Montreal), 4 PM in Calgary, 3 PM in Vancouver |
| Dispatch | Same day from New York for in-stock items ordered before the cut-off |
| Delivery to Canada | Typically 3–4 business days |
| Custom pieces | 4–6 working days after CAD approval, then shipping |
We ship to jewellers across Canada, from major centres such as Toronto, Vancouver, Calgary, Edmonton, Ottawa and Montreal to smaller independent stores. For full shipping and return details, see our shipping and returns page.
Wholesale Diamonds Toronto, Vancouver, Calgary and Montreal
Toronto
Toronto has the largest concentration of jewellery stores and manufacturers in Canada, and many of them already buy from New York. Because Toronto is on Eastern time, a store there can confirm an order at 5 PM and still have it leave New York the same evening. For Toronto jewellers searching for wholesale diamonds, the main advantage we offer is depth: certified lab-grown and natural diamonds, calibrated melee and matched pairs from one account, without waiting for a supplier to source each item.
Vancouver
Vancouver jewellers serve a demanding bridal market and often need specific shapes and ratios at short notice. With a 3 PM local cut-off for same-day dispatch, a Vancouver store can confirm a morning consultation's diamond the same day and have it in the store within a few business days.
Calgary and Edmonton
Independent jewellers in Alberta often run lean benches and rely on outside manufacturing. Our custom service, with a 24-hour CAD and no minimum order, lets a Calgary or Edmonton store say yes to custom requests without adding staff.
Montreal and Quebec
Montreal shares our time zone, which makes phone and WhatsApp ordering simple during the working day. Montreal designers frequently use our custom and private label service to produce small runs under their own brand.

A Typical Order From a Canadian Jewellery Store
To show how this works day to day, here is how a typical bridal order runs for a store in Toronto or Vancouver.
A client comes in on a Tuesday morning wanting a 2 carat oval on a pavé band in 18K white gold, with matching studs as a gift. The jeweller checks our certified oval inventory online, shortlists three diamonds by their IGI reports and messages our diamond desk on WhatsApp to confirm measurements and ratios. Within the same conversation the account manager confirms the calibrated melee sizes for the band and a matched pair for the studs.
The jeweller sends a quick sketch of the band. By Wednesday morning the 3D CAD render is back with the gold weight. The client approves it in the store. The ring is finished 4–6 working days later, shipped from New York and delivered to Canada typically in 3–4 business days. The studs, cut from in-stock matched pairs, can ship the same day they are confirmed if ordered before the cut-off.
The store has dealt with one supplier, one account manager and one set of invoices for the centre diamond, the melee, the pair and the finished ring. That is the core of what we offer Canadian jewellers.
Size Charts and Planning Tools
When planning a piece with a client, our diamond size chart converts carat weight to millimetre size by shape, and our ring size chart helps confirm finger sizes before a CAD is drawn. Our trade lab-grown diamond price list gives a starting point for quoting clients, with exact trade pricing visible once your account is open. Our education centre covers grading, shapes and certification for staff training.
