David Allouche Joins Grandview Klein Diamonds
The diamond industry veteran has been named its senior sales executive.

Allouche has joined the company with more than two decades of experience across the global diamond trade.
He brings extensive knowledge, proven leadership in sales and operations, and an entrepreneurial spirit that aligns with Grandview Klein to the role, it said.
“We are excited to welcome David to the Grandview Klein team,” said Moshe Klein, CEO of Grandview Klein Diamonds.
“His depth of industry experience, attentive customer service, and commitment to excellence will strengthen our ability to serve retailers and designers looking for premium natural diamonds with integrity and traceability.”
Allouche started his career with hands-on diamond cutting and polishing in 2000.
From 2001 to 2003, he worked at a diamond manufacturing factory operated by Rosy Blue in Russia, where he developed a foundation in large-scale production and quality control before joining Cora International in the United States.
Two years later, he was appointed to vice president of sales and operations at AnDiamond, doing business as Henri Daussi.
Over the next 18 years, he played a key role in driving strategic growth, streamlining operations, and building long-term relationships with retail and wholesale partners, said the company.
In 2022, Allouche launched his own business, Allouche Diamant, where he offered bespoke diamond solutions to select clientele and became a respected figure in the trade for his entrepreneurial approach and reputation for trust and professionalism, Grandview Klein said.
“I’ve long admired Grandview Klein for its exceptional inventory and its ability to craft creative, tailored marketing solutions for each of its retail partners,” said Allouche.
“Joining this team feels like a natural step in my journey, and I’m excited to contribute to the continued growth of a company I hold in such high regard.”
Grandview Klein said Allouche joins the company as it continues to expand its offerings, including a new diamond fine jewelry collection and an enhanced traceability program.
