Miriam born in 1951 ?
The Story of the Miriam Ring
In 1951, diamond cutter Wim Biallosterski purchased Coster Diamonds. It was only a few years after the Second World War, and the people of Amsterdam were slowly getting back on their feet. Wim gave Coster Diamonds new momentum. He created a close-knit and warm team that felt almost like a family—just as Coster Diamonds had originally been in 1840.
Who is Miriam?
One of the people who became part of the team was his daughter, Miriam Biallosterski. Miriam quickly became one of the top salespeople. She sold all kinds of diamonds and jewelry. But there was one ring she sold more than any other: a diamond entourage ring. This flower-shaped ring was part of our core collection and came in many different sizes and colors. Miriam adored this ring—so much so that she wore one herself. Over the years, people began referring to it as “the Miriam ring.” Miriam became the embodiment of this particular ring.
What does it look like?
Even now, 60 years later, we can still see why Miriam loved this ring so much. To this day, it remains one of our most popular designs. We consider it one of our Coster Classics because of its timeless design. The ring features a single diamond as the center stone, surrounded by six or eight slightly smaller diamonds. It has a split shank, giving the ring an open and elegant appearance.
Fun fact.
Eleven years after Wim Biallosterski, Ben Meier became CEO of Coster Diamonds. Coincidentally, he also had a daughter named Miriam. Mirjam Meier also became a sales representative at Coster. As a result, when people spoke about the Miriam ring, many assumed it was named after Ben’s daughter. But the true story is that the Miriam ring is a tribute to the daughter of the man who rebuilt Coster after the war.
