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!

Red Diamond and Blue Diamond

Time and time again the notion of diamonds being rare has been displaced. There are exceptions to everything. Red diamonds and blue diamonds are amongst the most highly sought collectors items in the world. Their scarcity is unmatched. Most recently, a 12.11 carat fancy intense blue diamond sold for approximately $1.3 Million Per Carat! Sotheby’s Auction House estimates this 1.38 ct Red Diamond to sell for $1.8 to $2.8M USD!
