Why are natural pink diamonds so expensive?
Natural pink diamonds are so expensive because they are incredibly rare and highly sought after. Only a tiny fraction of all diamonds mined in the world are natural pink diamonds, and most of these are small in size and low in quality. It is estimated that less than 0.1% of all diamonds mined are natural pink diamonds.
The intense pink color in natural pink diamonds is caused by a structural irregularity in the diamond's crystal lattice, which causes it to absorb light differently than a white diamond. The stronger and more even the pink color, the more rare and valuable the diamond becomes.
The combination of extreme rarity and high demand from collectors, investors, and high-end jewelry buyers has led to sky-high prices for natural pink diamonds. In fact, some of the most expensive diamonds ever sold at auction have been natural pink diamonds, including the Pink Star, which sold for over $71 million in 2017.
It's also worth noting that the price of natural pink diamonds can vary widely depending on their size, color intensity, clarity, and cut quality. The larger and more vividly colored the diamond, the more valuable it becomes.
