Tomorrow, April 12th, Christie’s will auction a 10.09 carat cushion cut Fancy Vivid Purple-Pink diamond in New York. This rare and exceptional diamond is estimated at $12,000,000-15,000,000. The past 15 months, there has been a huge demand for large & rare fancy color diamonds. In December I posted that a 6.89 carat Fancy Vivid purplish-pink diamond sold for $6.9 million or $1 million per carat. So, do you think the trend will continue? Will Christie’s see double digits?
