Harry Winston is a world-famous jewelry brand known as the "King of Diamonds".

Founded in 1890 in New York, Harry Winston was founded by Jacob Winston, the grandfather of the current owner, Ronald Winston, as a small jewelry and watch workshop in the Manhattan area. Jacob, who immigrated to New York from Europe in 1890, was a craftsman known for his craftsmanship. He founded a business that was later succeeded by his son, Harry Winston, who was Renault's father. With a natural business acumen and a keen eye for high-quality diamonds, he successfully marketed jewelry to New York's wealthy upper class and founded his first company at the age of 24.

As a world-renowned super jewelry brand for more than 100 years, the exquisite craftsmanship and careful consideration in cutting diamonds can always increase the value of diamonds several times over.
