William Dean Platinum was inspired by the birth of my sons, William and Dean, and carries on a proud family tradition in precious metals. It all began in 1936 with my grandfather, George Lambros, who started a refining company in New York City, pioneering innovations like Rhodium and Palladium plating solutions. Later, my father, Dean Lambros, expanded the business into precious metal dealing, supplying iconic names like Tiffany & Co., Cartier, and Harry Winston.
When I joined, the focus shifted to manufacturing platinum jewelry, creating the finest die-struck wedding bands known for unmatched density, polish, and quality. Now, as the fourth generation steps in, we’re evolving again—bringing timeless platinum bridal and fashion jewelry directly to you online. Every piece is crafted with the highest-quality natural diamonds and gemstones, ensuring beauty and value that lasts a lifetime. William Dean Platinum is where tradition meets modern craftsmanship.
