WHOLESALE DIAMOND SUPPLIER IN SURAT
Diamond Supplier in Surat: Natural & Lab Grown Diamonds for Local Manufacturers
We’re Mann Gems LLP, a certified diamond supplier in Surat working with manufacturers and exporters who cut, polish, and set diamonds every day of the week. We supply loose natural diamonds and lab grown diamonds, in all eleven shapes, from melee to solitaire sizes. Surat handles the largest share of diamond cutting and polishing on earth, and manufacturers here need a supplier who understands production timelines, not just retail orders. Whether your unit is in Mahidharpura, Varachha Road, Katargam, or one of the newer offices at Surat Diamond Bourse, we work around your production schedule rather than the other way around.
Every quote we give on wholesale diamonds in Surat reflects current market rates, and every certified diamond is graded under GIA or IGI before it reaches you. Tell us the carat range, shape mix, and certification tier your production run needs and we’ll work from there. Regular manufacturers get priority on stock during tight supply periods, and the same team handles sourcing and dispatch on our end, so what reaches your unit matches what you were quoted. Whether you’re looking for a Diamond Wholesaler in Surat for a running order or a Bulk Diamond Supplier in Surat for a single large parcel, we quote both the same way, against live stock.
THE SURAT DIAMOND TRADE
Why Surat Is the Diamond Cutting Capital of the World
Surat cuts and polishes close to 90 percent of the world’s rough diamonds, and the city employs several hundred thousand workers across cutting and polishing units. Mahidharpura has been Surat’s core diamond market since the 1960s, Varachha Road has grown into a hub of retail showrooms and workshops, and Katargam carries a large share of the city’s polishing units. More recently, the Surat Diamond Bourse opened in Khajod on the edge of the city, built as the world’s largest office complex to bring trading, certification labs, and customs clearance under one roof, work that manufacturers previously had to route through Mumbai.
For a manufacturer already cutting and polishing in Surat, sourcing rough or certified loose stock from a Surat Diamond Bourse supplier based in the same city cuts out a layer of transit time and cost that a Mumbai or Delhi based supplier can’t avoid.
Diamond Quality Standards
Every stone we supply, natural or lab grown, is checked against the 4Cs before it goes out to a Surat buyer:
- Cut: how well the diamond handles light, which has the biggest effect on how it actually looks once set.
- Color: the range from colorless through faint yellow, with colorless stones commanding the higher price.
- Clarity: what’s visible inside and on the surface of the stone; fewer inclusions means a rarer, more valuable diamond.
- Carat: the raw weight of the stone, where price increases faster than weight as size goes up.
We also check finish and symmetry on every parcel before it ships, so what a manufacturer receives matches what was confirmed at the time of order.

What We Supply: Natural & Lab Grown Diamonds
We supply both natural diamonds and lab grown diamonds to jewelry manufacturers, wholesalers, and exporters across Surat, each one independently certified before it leaves our office. Here’s what’s available:
Natural Diamonds: Mined From the Earth, Cut and Polished in Surat
As a Natural Diamond Supplier in Surat, we work with stones that take billions of years to form underground, and every one we sell is graded on cut, color, clarity, and carat before it’s certified. For export houses and bridal focused manufacturers working out of Mahidharpura and Varachha Road, that origin story still carries weight with the end customer.
Available to buyers in Surat:
Lab Grown Diamond Supplier in Surat
Lab grown diamonds are chemically and optically identical to natural stones. The only real difference is how they’re formed, using HPHT or CVD technology in a lab setting instead of underground pressure over millions of years. Surat is home to a large share of India’s CVD manufacturing capacity, and demand for certified lab grown stock among local units has grown fast as a result. As a CVD Diamond Supplier in Surat, we supply:
- Round and fancy shape lab grown diamonds
- Certified lab grown diamonds with full grading documentation
- Rose cut and mix cut fancy lab grown diamonds
- Loupe clean and white lab grown diamond categories
- Solitaire grade certified lab grown diamonds
Loose Diamond Supplier in Surat
What we supply is unset, loose diamonds, nothing more. Manufacturers and exporters across Surat take it from there and cut, polish, or set it under their own brand. We stay out of the finished jewelry side of the business entirely; we just supply what goes into it.
Diamond Shapes Available in Mumbai
We select parcels across all eleven commercially traded diamond shapes that manufacturers in Surat order for bridal jewelry, engagement rings, and fashion pieces.

Stock ranges from melee sizes for pavé and accent work up to solitaire grade centre stones for bridal pieces. Carat availability is confirmed against live inventory at the time of enquiry, since stock and pricing shift daily.
Every certified stone we supply carries a grading report with an independently verifiable report number. As a source for GIA Certified Diamonds in Surat and IGI Certified Diamonds in Surat, we cover both natural and lab grown categories, with every parcel counting as Certified Loose Diamonds Surat buyers can check against the accompanying report before it ships.
GIA (Gemological Institute of America): the industry benchmark for strict, consistent grading.
- IGI (International Gemological Institute): a leading lab for both natural and lab grown certification, widely used across the Surat trade.
We supply jewelry manufacturers, wholesalers, and exporters right across the city, from established Mahidharpura and Varachha Road trading houses to newer offices at Surat Diamond Bourse and manufacturing units in Katargam.
e supply jewelry manufacturers, wholesalers, and retailers right across the city, from established Zaveri Bazaar and Opera House trading houses to smaller manufacturing units in Andheri, Malad, Borivali, and Thane sourcing directly for the first time.
Bulk is the standard here, not the exception. We work in carat ranges, shape mixes, and certification tiers rather than one-off retail sales, and order size is set by what a manufacturer actually needs rather than a fixed minimum. Several of our Surat buyers start with a trial parcel before moving to a regular running order.
Every shipment is packaged to protect the stones in transit and sent through insured courier with tracking. GST invoicing and HSN classification are provided with each shipment, and certification documentation travels with the parcel so it can be checked against every stone on arrival. We include a standard conflict-free sourcing statement with each shipment, in line with Kimberley Process requirements.
Natural diamonds and lab grown diamonds fall under separate HSN classifications for GST purposes in India, and GJEPC guidance requires that invoices clearly state whether a stone is natural or lab grown. Every lab grown diamond we supply is certified and billed as lab grown from the start, so that classification is already built into your paperwork before the stone reaches you.
