Mbuji-Mayi: diamonds, dust, and a dude named Papa Jean who knows stuff

@Freya Holm2/7/2026blog

so you wanna know about mbuji-mayi? okay, pull up a stool. this isn't some polished brochure. i’ve been talking to this old guy, papa jean, who runs a crumbling library near the mbuji river. he’s got the dirt, the real numbers, not the stuff they print for foreigners. we’re doing this q&a style because my brain can’t handle another chronological list.

*papa jean, what’s the actual vibe here? like, the origin story, don’t sugarcoat it.

"sugarcoat?" he cackled, spitting tobacco. "this place was
nothing. just forest and the mbuji river. then, 1907, some belgian geologist found a pebble. a shiny rock. turns out it was the tip of the biggest industrial diamond deposit on god’s green earth. they called it the bakwanga mine. the belgians didn’t build a city, they built a cage. a company town for the联合 minières. they gave it a name that sounds like a cough: mbuji-mayi. it’s 'goat water' in tshiluba. because the river was so dirty, only goats would drink it. still kinda true."

so it was all about the rocks? always?

"always. even now. you think it’s about people? no. it’s about carbon under pressure. literally and figuratively. the.$congo got independence in 1960, and we got a guy named albert nyembo, who ran the provincial diamond monopoly. he was... flexible. then mobutu came. he renamed the city... again. this time to
mbuji-mayi officially, but everyone still called it bakwanga. the mine was the state, the state was the mine. then the 90s, the soviet bloc collapsed, demand for industrial diamonds crashed. the big mine shut. tens of thousands thrown out. the city just... deflated. like a tire with a slow leak."

what about now? the job market, rent, can i actually live here?

he slides a crumpled newspaper across the table. "look. the official unemployment rate is a joke. they say 30%. real? maybe 60, 70%. the big mine is half-dead, run by a chinese consortium. they hire 500 people. 500. for a city of, what, 2 million? you do the math. rent? a one-bedroom in a decent part like diulu? maybe $150 usd a month. but the power goes out 4 days a week. the water? you buy it in jerrycans. safety?" he leans in. "don’t walk at night. not in most areas. the diamond smugglers, the 'negociants,' they run their own little fiefdoms. if you’re a foreigner with a camera, you’re a target. not for muggings necessarily. for 'friendlies' who want to show you a 'real diamond deal.' run. it’s always a scam or you’ll get your visa problems."

what’s it feel like on the ground?

it’s red dust. everywhere. in your teeth, on your flip-flops, coating the mangoes at the market. the air is thick with woodsmoke and the weird, sweet smell of fermenting cassava. the sounds? preaching from a hundred churches, theConstant
thump-thump-thump of a generator, and the high-pitched yell of kids selling phone credit: "mille! mille!" the weather? right now it’s that wet-hot that makes your shirt stick to your back before you even step outside. the neighbors are kananga, maybe 6 hours on a death-trap road, and kinshasa, a two-hour flight on a plane that looks like it’s held together with hope and chewing gum.

okay, give me the straight talk. the rumors. what do people actually whisper?

"overheard at the bar, three nights ago: 'don’t ever agree to a diamond deal in a hotel room. they have fake police.' another one: 'the new chinese mine is just strip-mining the last bits. they’ll be gone in ten years, leaving a hole you can see from space.' and my favorite,' he grins, 'that if you find a pink diamond in the river, you’re blessed by the spirits. but you’ll also be followed for the rest of your life.' pretty good odds, no?"

so what’s the point? why is this place not just a ghost town?

"because of the people, you idiot," he says, suddenly serious. "we’re not just a mine. we’re a market town. we feed the kasai. the university is here. there are mechanics who can fix anything, tailors who work miracles on a sewing machine, teachers who show up for $20 a month. there’s a scene. a stubborn, chaotic, humming scene. you want a real meal? go tochez marie on avenue invo. tell her papa jean sent you. she’ll serve you
fumbwa (cassava leaves stew) that will make you forget you ever wanted diamonds. and go to the mbujimayi university campus. those kids? they’re the future. they’re on facebook, arguing about politics, starting little businesses. the city is a pressure cooker. but pressure makes... well, sometimes it makes diamonds. sometimes it just makes a big mess. right now? it’s both."

final pro-tip?

"bring cash. us dollars. lots of small bills. the atms are myths. and for the love of god, if someone offers you a 'historical tour' of the old mine shafts, say no. there are no lights down there. only memories and bats."

[drunk advice from a物流 guy in kikwit: "mbuji-mayi airport runway is so cracked, the plane lands on faith and a prayer."]

[something a peace corps dropout warned me: "the tap water isn't just dirty. it's a biological experiment."]

if you go, go with eyes wide open. it’s not a vacation spot. it’s a lesson. in extraction, in resilience, in how a place built on a rock can have a soul made of dust and defiance.
