Art Nouveau bird brooch set with sapphires in yellow gold and a baroque pearl.

The Darya-i-Noor is the largest pink diamond and one of the largest cut diamonds on the planet. Though the exact weight is unknown, it’s estimated around a massive 182 carats. The stone is valued at $16.5 billion.
Supposedly the Darya-i-Noor was once part of a larger diamond that was cut in two. The smaller piece is now with the Iranian Crown Jewels, but the larger stone? While its exact location has sparked debate, Iran claims it is currently stored in their Central Bank. The sparkler was originally mined in India and owned by Mughal emperors before Iran invaded the country and took the gem, along with other precious treasures. We know that in its time, the Darya-i-Noor has been worn as an armband, a brooch, and a decoration on military hats.
