A 300-million-year-old pink diamond was displayed in St. Petersburg.
The Alrosa company presented a rare pink diamond weighing 3.07 carats, TASS reported. The cost of the unique stone is estimated at more than 1.5 million dollars.
As noted by gemmologist Natalya Kruglova, pink and blue diamonds are the real treasure of the earth, as they make up only 0.1% of the total world production.
The most impressive thing about this diamond is its age. The stone is about 300 million years old, and it was mined in 2025.
