Another invaluable piece that was part of María Unzué's collection is the famous blue diamond, also known as "Diamante Unzué", which she acquired at the Cartier jewelry store in Paris in 1910. It was set in a devant de corsage brooch , which simulated thrush flowers. The diamond was found in South Africa, and between 1909 and 1901 it was cut into a heart shape by the French jeweler Atanik Eknayan. In 1959 Mr. Harry Winston purchased the brooch, removed the diamond, and set it in a ring. She later sold it to Mrs. Marjorie Merriweather Post, who eventually donated it to the Smithsonian Institution in Washington DC, where it remains on display today as one of her most important gems, near the also famous "Hope Diamond".

Some assume that the "Blue Heart Ocean" diamond from the movie "Titanic" (1997) is inspired by the shape and color of the "Diamante Unzué", which, coincidentally, is on display at the Smithsonian under the name "Blue Heart Diamong Ring". »
