Christie’s & Sotheby’s Most Rare Alexandrites

Natural Alexandrite

In 2014, Christie’s auctioned off a 21 carat Russian Alexandrite in Geneva Magnificent Jewels, Switzerland.  The pre-auction valuation of $450,000-$650,000 Swiss Francs (USD Equivalent about the same) was grossly underestimated. The final price: $1,325,000 CHF! This amounts to a whopping $60,000 USD per carat!
