A Different Eye for the Stones
A three-million-dollar deal would be sealed on a little slip of paper and a handshake. That was all it took. The business was built on trust — and I built my life on it. Malka Roizen, President
Malka Roizen is among the very few sole-proprietor diamond specialists who is a woman. She brings a different eye to the stones — a perspective her customers have come to value as much as her precision. Her story begins long before Baguette Mondial, in a trading hall that didn’t want her there at all.
The Trading Floor
Malka was twenty-one, fresh out of the Israeli army, when a family friend brought her into the diamond bourse in Ramat Gan — Israel’s diamond district. She studied by night and worked the floor by day, stepping each morning into a world of fortunes and back out each evening into ordinary life. It was a man’s world, and many objected to a woman joining them in the hall.
On her first day, a man closed the door on her as she carried in the coffee, and everything fell to the floor. Within a week, she says, if her belt skipped a buckle they would turn to let her know — they had become her family. Acceptance came from how she carried herself, and from an ethic her boss drilled into her: honesty, accuracy, no games. She watched deals worth millions close on nothing but a handshake and a slip of paper. Once, simply passing a table, she was asked to hold a fancy red diamond — among the rarest in the world — and in holding it became the broker on the deal.
I can look at a stone and tell you if it’s mine or not. That deep looking has stayed with me forever.
Baguette Mondial
When Malka came to the United States, she set out to open her own diamond office. A well-known manufacturer in Israel — a deeply religious man from Belz she had befriended years earlier on the trading floor — offered a partnership: he would manufacture in Israel, she would run Miami. She named the company Baguette Mondial, after the baguettes and fancy square cuts he specialized in.
Success came almost at once. In her first week, jewelers filled her office and she worked until nine at night — because she knew the stones, knew how to sort them for the exact piece each customer was making, and understood what most didn’t: when everything ships by mail, you get one chance to be right. Over the years she expanded far beyond baguettes into all sizes, fancy cuts and fancy colors, and the business grew on her name alone.
Measured Exactly
Malka personally calibrates every stone she sends — round, oval, marquise or radiant — checking length, width and depth against each customer’s request. Ask for a 1.3 mm round and you receive a 1.3 mm round; not something close, exactly that. Because shipping and insuring stones is costly, that accuracy saves her customers real money and spares them the returns most suppliers make routine.
She works as a partner, not just a source. When a store can picture a piece but isn’t sure what it needs, she pulls stones from inventory, photographs them side by side at different measurements, and sends images the store can show its own customer — a selection of shapes and sizes, with easy returns on the rest. Ask for F color, and F color arrives. In all her years she has never had a stone rejected for failing to match what was requested — a record she counts among her proudest.
People trust me. They don’t even check my goods anymore.
