History of Marquise and Baguette Diamond Engagement Ring

The marquise cut, also known as the navette cut, dates back to 18th-century France when King Louis XV commissioned a diamond cut to resemble the shape of the smile of his mistress, Marquise de Pompadour. This elegant, elongated shape experienced a major revival in popularity during the mid-20th century, particularly from the 1960s through the 1980s, often paired with sleek geometric cuts like the baguette, which defined sophisticated engagement jewelry of that era.
