From Polishing Wheel
to Diamond Exchange
S.RONEN DIAMOND LTD was not built in a boardroom. It was built over four decades, stone by stone, at the polishing wheel and at the trading table of the world's most respected diamond exchange.
Born Into It
In 1984, a 17-year-old named Ronen Seren walked into his first diamond workshop. His father had spent 24 years as a polisher before him, so the craft was not a career choice. It was an inheritance.
For the next two decades, Ronen cut and polished diamonds by hand. He developed an instinct for color, clarity, and proportion that no classroom can replicate. He learned to see what others overlooked.
In 2007, he founded S.RONEN DIAMOND LTD. In 2008, he became a licensed member of the Israel Diamond Exchange, not as a newcomer to the trade, but as a craftsman with nearly 25 years of hands-on experience already behind him. Today, Ronen is internationally recognized as one of the world's leading specialists in natural fancy color diamonds, sought for his rare ability to evaluate both rough and polished stones with equal authority.
The Hands That Polished Red Diamonds
Among the rarest objects on Earth are natural red diamonds, stones of such extraordinary scarcity that only a handful of people alive have ever worked with one.
Ronen Seren is among them. He has personally polished natural red diamonds with his own hands.
That is not a credential. That is a lifetime of mastery.
