surat diamond market visitor guide (2026) - where 90% of world's diamonds are cut

tldr: surat cuts and polishes 90% of the world’s diamonds. yes, nine out of ten. the city has 15,000+ cutting units, 800,000+ workers, and the world’s largest office building (surat diamond bourse). tourists can visit retail markets at mahidharpura and varachha freely. factory visits require connections. loose diamonds can be 15-30% cheaper than metro city retail, but only if you know what you’re buying. always insist on GIA or IGI certification. full breakdown below.

i haven’t bought diamonds in surat personally. this guide is research-backed, compiled from industry reports, local trader interviews published in media, diamond trade publications, and recommendations from people who work in or around the surat diamond industry. i’ll be upfront about what’s verifiable fact and what’s practical advice.

this guide exists because, somehow, nobody has written a proper visitor guide for the place where 90% of the world’s diamonds are cut and polished. you can find a million blog posts about visiting the taj mahal. but visiting the city responsible for nearly every diamond on every engagement ring on earth? nothing. that’s the gap this fills.

surat is primarily known in india for two things: textiles and diamonds. the textile side is visible everywhere. the diamond side is mostly invisible unless you know where to look. this guide tells you where to look.

surat and diamonds: the numbers

the scale of surat’s diamond industry is genuinely hard to comprehend. here are the numbers.

fact	number
share of world’s diamonds cut and polished in surat	~90%
diamond cutting and polishing units	15,000+
people employed in surat’s diamond industry	800,000-900,000
peak workforce (pre-2020)	1.2 million across 18,000 units
peak export value (2021-22)	$25.48 billion
export value (2024-25)	$13.29 billion
most common cut	round brilliant (65% of production)
the surat diamond bourse	world’s largest office building

nine out of ten diamonds in the world pass through surat. not india. surat. one city in gujarat. a diamond mined in botswana, shipped to antwerp, gets sent to surat for cutting and polishing, then goes back to antwerp or new york or hong kong for retail. surat is the factory floor of the global diamond industry.

the industry is dominated by the palanpuri jain community, originally from palanpur in north gujarat. starting in the 1960s, they found a niche that changed global diamond trade forever: processing smaller, lower-value stones that antwerp’s cutters didn’t want to deal with. surat had the skilled labor. the palanpuris had the trade connections. the combination created a monopoly that still stands today.

the business model was simple and brilliant. buy rough diamonds cheaply from antwerp (especially small stones with thin margins). send them to surat where skilled workers would cut and polish them for a fraction of what it cost in belgium. sell the finished stones back to the global market. repeat at massive scale. over six decades, this scaled from a niche operation to processing almost every diamond on earth.

but the industry is in transition. exports dropped 48% from their 2021-22 peak to 2024-25, driven by global demand softening, competition from lab-grown diamonds, and economic headwinds. surat is adapting. many units are now producing lab-grown diamonds using CVD (chemical vapor deposition) technology. the city has between 8,000-10,000 CVD reactors in operation, double from just two years ago. the factories that once only cut natural diamonds now grow them too.

the surat diamond bourse

the surat diamond bourse deserves its own section because it’s an architectural and economic story in itself.

the basics. inaugurated in december 2023, it’s the world’s largest office building, confirmed by guinness world records in august 2023. it’s bigger than the pentagon. nine interconnected towers, 15 floors each, spread across 35+ acres, with over 4,200 offices. it was designed by morphogenesis, one of india’s top architecture firms.

the vision. the idea was to move surat’s entire diamond trade, scattered across mahidharpura, varachha, and other old-city areas, into one consolidated mega-complex. custom clearance for imports and exports, certification labs, conference halls, restaurants, banks, a national diamond research institute, international education facilities, and even hotels. everything the diamond trade needs under one roof.

the reality (as of early 2026). occupancy is around 2%. roughly 175 offices are operational out of 4,200+. about 35 major traders and 65 smaller traders and brokers have moved in. all 4,700+ offices have been sold, but most owners haven’t moved their operations yet. the traditional markets at mahidharpura and varachha are deeply entrenched, with relationships and infrastructure built over decades. moving to a new complex on the outskirts of the city is a big ask.

the government pushed for all offices to begin operations from january 23, 2026, and there’s been some momentum. but it’s slow. the bourse’s location, away from the traditional trading areas, and connectivity challenges have made the transition harder than planned.

can you visit? it’s not a tourist attraction. it’s a business complex. you can’t just walk in and look around. access is for traders, brokers, and people with business appointments. that said, the building itself is impressive from the outside, and if you happen to know someone who works there, a visit is worth arranging. the scale is unlike any office building you’ve seen.

how the diamond process actually works

this is the part most visitors find fascinating. a rough diamond looks nothing like what you see in a jewellery store. the transformation happens in surat’s workshops, and it follows roughly these stages:

1. sorting and planning. rough diamonds arrive (mostly from africa, russia, and canada). each stone is analyzed using computer software to determine how to cut it for maximum yield. a 1-carat rough stone might yield a 0.4-carat polished diamond. the planning stage decides how much of the stone’s potential is captured.

2. marking. the diamond is marked with precise lines showing where cuts should be made. this used to be done entirely by hand. now it’s laser-guided.

3. sawing. the rough diamond is cut along the marked lines using a copper blade coated in diamond powder and oil. yes, it takes a diamond to cut a diamond.

4. bruting (girdling). the sawn diamond is placed in a lathe and shaped against another diamond to create the round outline. this is where a rough chunk starts looking like a diamond.

5. faceting. the blocker places the first 18 main facets. then the brillianteer adds and polishes the remaining 40 facets for a standard 58-facet brilliant cut. this is where the sparkle happens.

6. final inspection and certification. the polished diamond is boiled in acid to remove dust and oil, then inspected and graded. it’s then sent to a certification lab (GIA or IGI, both have labs in surat) for independent grading.

each diamond goes through approximately 36 individual processes. in surat’s larger factories, this is a production line with hundreds of workers, each specialized in one or two steps. the skill level is remarkable. these workers cut stones as small as 0.01 carats (smaller than the head of a pin) with 58 perfect facets.

where to actually buy diamonds in surat

three main areas. each serves a different buyer.

mahidharpura (badi bazaar)

this is the original. the oldest and most iconic diamond trading area in surat. located in the old city (pincode 395003), mahidharpura has been the heart of surat’s diamond trade for over six decades.

what it looks like: a narrow street market with shops on both sides, except instead of selling clothes or food, every shop deals in diamonds. the shops have diamond testers (CVD machines) so buyers can verify what they’re getting. the energy is intense. brokers walk between shops with folded paper packets of loose stones. deals happen over chai.

who it’s for: traders, brokers, and serious buyers. this is wholesale territory. shops do sell to retail customers, but you need to know what you want. walking in and saying “i want a diamond” without any knowledge of the 4Cs (cut, clarity, color, carat) will not go well for you.

timings: roughly 11 am to 8 pm, though individual shops vary.

what to expect: don’t expect a polished retail experience. this is a trading floor. shops are small. there’s no air-conditioned showroom with mood lighting. but the prices reflect the lack of retail overhead.

varachha mini bazaar

about 15 minutes from mahidharpura. similar vibe but slightly more modern. smaller traders and brokers. if mahidharpura feels overwhelming, varachha is a marginally less intense version of the same experience.

surat diamond bourse

the newest option. a few offices within the bourse are retail-facing, but most of the (limited) activity is still B2B. this will likely change as occupancy increases, but for now, it’s not where most retail buying happens.

retail jewellery showrooms

if you want the conventional jewellery-store experience with polished interiors and customer service, surat has plenty of branded and local jewellery showrooms in areas like ghod dod road, ring road, and vesu. these shops sell finished diamond jewellery at retail prices with making charges and GST. the diamond-specific price advantage of buying in surat is mostly lost here, but you get the convenience of a normal buying experience.

---

what makes surat diamonds cheaper (and when they’re not)

the core price advantage of buying in surat is simple: you’re buying at or near the source.

the typical diamond supply chain looks like this:

mine (africa/russia/canada) > rough dealer (antwerp/mumbai) > cutting unit (surat) > polished dealer > wholesaler > retailer > you

each step adds a markup. in surat, you can potentially buy at step 3 or 4 instead of step 6. that can mean 15-30% less than what you’d pay at a retail jeweller in mumbai, delhi, or new york.

but here’s the catch. this advantage only applies to loose diamonds bought from traders who normally sell to other businesses. the moment you walk into a retail showroom in surat, the price equalizes. making charges, GST, brand premium, and retail overhead close the gap.

the real savings require:

• knowledge. you need to understand the 4Cs and be able to evaluate what you’re looking at. or bring someone who can.
• a local contact. having someone in the diamond trade who can introduce you to trusted dealers makes an enormous difference. cold-walking into mahidharpura as a tourist and negotiating a fair deal is very difficult.
• buying loose stones. the savings are on unset diamonds, not finished jewellery.
• volume or value. the better deals come at higher values. buying a single small stone as a tourist? the savings might not justify the trip. buying a 1-carat solitaire for an engagement ring? now the math starts making sense.

be realistic. if you don’t have diamond knowledge or a local contact, you’re better off buying from a reputable certified retailer in your own city. the surat advantage is real but requires effort to access.

the lab-grown diamond angle

surat isn’t just the natural diamond capital. it’s rapidly becoming a major player in lab-grown diamonds too.

lab-grown diamonds are chemically and physically identical to natural diamonds. they’re made using CVD (chemical vapor deposition) technology in controlled environments. surat now has 8,000-10,000 CVD reactors, double from just 2-3 years ago.

why this matters for buyers: lab-grown diamonds are typically 70-85% cheaper than natural diamonds of the same size and quality. if you’re visiting surat and don’t care about the “natural” distinction, lab-grown is where the dramatic price advantage is.

the important distinction: always make sure you know what you’re buying. a lab-grown diamond should be clearly disclosed and certified as such. both GIA and IGI certify lab-grown diamonds. if a seller is offering a “natural” diamond at a suspiciously low price, it might be lab-grown. this is where certification becomes non-negotiable.

many of surat’s traditional cutting and polishing units now handle both natural and lab-grown stones. some factories have pivoted entirely to lab-grown as natural diamond exports have declined.

visiting tips for tourists

practical basics

• best time to visit: october to february. surat is hot and humid for most of the year. winter is comfortable for walking through markets. the diamond trade operates year-round, but there can be slowdowns during major gujarati festivals (uttarayan in january, navratri in october) when many workers go home.

• what to wear: the markets are in old surat. narrow streets, crowded, no AC in most shops. dress comfortably. nothing flashy. you’re visiting a wholesale market, not a luxury boutique.

• language: gujarati is the primary language. hindi works in most shops. english is limited to the larger, more established dealers.

• photography: don’t photograph inside shops or factories without permission. security is tight in the diamond trade. cameras make people nervous. asking politely goes a long way, but expect refusals.

• how to get there: mahidharpura is in old surat, reachable by auto-rickshaw or cab from anywhere in the city. tell the driver “mahidharpura diamond market.” everyone knows it. from surat railway station, it’s about 15-20 minutes. from the airport, about 30-40 minutes.

what to do (and what not to do)

do:

• go with a local contact if possible. a friend, a friend’s friend, anyone with connections in the trade. this changes the entire experience.
• start at mahidharpura just to see the market. even if you don’t buy, the atmosphere is unlike anything else in india.
• visit the diamond gallery at surat science center (3rd floor) for an accessible, tourist-friendly introduction to diamond cutting and polishing. old machines, history, different types of diamonds. good starting point.
• ask questions. most traders are happy to explain the trade to genuinely curious visitors. the diamond community in surat is proud of what they’ve built.
• if buying, get everything in writing. certification number, stone details, price, receipt.

don’t:

• walk into mahidharpura expecting to negotiate like you’re at a street market. diamonds are precision-priced. there’s some room for negotiation, but it’s not like bargaining for clothes at a bazaar.
• buy uncertified stones. ever. if someone says “no need for certificate, i’m giving you a good price,” that’s exactly when you need the certificate most.
• carry large amounts of cash visibly. the diamond market is heavily secure with cameras everywhere, but common sense applies.
• expect factory tours without prior arrangement. you can’t just show up at a cutting unit and ask for a tour. these are active workplaces with serious security.
• confuse “american diamonds” with real diamonds. “american diamond” is the indian market term for cubic zirconia. it’s worth almost nothing.

how to verify what you’re buying

this section might save you a lot of money. or prevent you from losing it.

certification is non-negotiable

the only way to know what you’re buying is certification from a recognized gemological lab. in india, three labs matter:

GIA (gemological institute of america). the gold standard globally. GIA has a lab in surat. a GIA certificate means the diamond has been independently graded by the most trusted lab in the world. highest resale value.

IGI (international gemological institute). widely used in india and very reliable. IGI also has a lab in surat. slightly less weight than GIA internationally but perfectly reputable. most common certification for lab-grown diamonds in india.

SGL (surat gemological laboratory). local lab, decent for domestic purposes but less recognized internationally.

verify the certificate online

this is the step most people skip, and it’s the most important one.

• GIA: go to gia.edu, use the report check tool, enter the certificate number. the stone’s details should match exactly.
• IGI: go to igi.org, use the verify your report tool, enter the number.

fraudulent GIA certificates have been found in surat. in at least one documented case, a dealer was selling lab-grown diamonds with fake GIA inscriptions. the certificates looked real. the laser inscriptions on the diamonds looked real. but the online verification would have caught it immediately.

always verify online. always.

check the laser inscription

most certified diamonds have a microscopic laser inscription on the girdle (the thin edge) that matches the certificate number. ask the dealer to show you this under magnification. then verify that number online.

get an independent evaluation

if you’re making a significant purchase (rs 50,000+), consider getting the stone independently evaluated by a gemologist before finalizing. both GIA and IGI have offices in surat. the evaluation fee is small relative to the purchase price.

the diamond trade expo (carats)

if you time your visit right, the CARATS surat diamond expo is an annual trade show held at the surat international exhibition and convention centre. it’s primarily a B2B event, but it gives a concentrated view of surat’s diamond industry. check dates for the current year before planning.

is it worth traveling to surat just for diamonds?

honest take: it depends on what you want.

yes, if: you’re making a significant diamond purchase (engagement ring, investment stone) and have either diamond knowledge or a trusted local contact. the savings on a 1-carat+ solitaire could easily cover your travel costs and then some. also yes if you’re genuinely fascinated by how industries work at scale. watching a city that processes 90% of the world’s diamonds is a unique experience.

no, if: you want to buy a small piece of diamond jewellery for personal use. the retail experience in surat isn’t meaningfully cheaper than any other city for finished jewellery. you’re better off buying from a certified retailer near home.

the smart play: combine it with a broader gujarat trip. surat has incredible food (it’s arguably the food capital of gujarat), a growing cafe scene, and enough to fill 2-3 days. add ahmedabad and vadodara and you have a proper gujarat trip where the diamond market is one highlight among several, not the only reason for the journey.

surat’s diamond industry is one of those things that sounds like it can’t be real until you see the numbers. one city. 90% of the world’s diamonds. 800,000 workers. the world’s largest office building, built just for diamond traders. the scale is mind-boggling, and the fact that it’s barely known to tourists makes it all the more interesting to visit.
