Welcome to AGTA GTC's Laboratory Update for April 14, 2005

Ruby Sets New Auction Record
On April 12, the ruby world was abuzz with the news that a new auction record had been set at Christie's New York. The final hammer price of $2.2 million yielded a staggering $274,656 per carat for the 8.01 ct. gemstone, which was purchased by a private client in Asia. This bested the previous record of $228,252/ct. set back in 1988 with a 15.97-ct. gemstone.

    Untreated rubies of this quality and size are exceedingly rare, and demand for them grows ever stronger. The AGTA Gemological Testing Center's Director, Dr. Lore Kiefert, attended the auction and described the piece as "one of the finest rubies I've ever seen." The AGTA Gemological Testing Center is America's premier colored gemstone testing facility. We will regularly provide you with the latest news from the colored gemstone and gemological world.
