Even during a global pandemic, top end colored gemstones continue to sell.
On October 7, Sotheby's Hong Kong, a 6.41-carat unheated Burmese ‘Pigeon’s Blood’ ruby mounted on an 18k yellow and white gold ring surrounded by French-cut diamonds was offered for sale.  Accompanied by AGL report no. CS 65283, dated December 12, 2014 and an AGL Jewelfolio™.  AGL graded the color 2.5 or 70% red, often used to define "Pigeon Blood" Red.
“Less than 10% of all gem-quality rubies are unheated, making them both rare and impressive,” the auction house said. “Darker rubies are often heated to enhance their shade, but unheated rubies are naturally intense and vibrant.”
The estimate was $2.2 million - $2.8 million.  It sold for $2.8 million ($432,000 per carat) or the high end of the estimate.   In 2013 at Christie's, a  13.21 Burma Ruby sold for over $5.9 million for $446,000 per carat.  Now Burma ruby stones are close to this amount at about 1/2 the size.  Our only conclusion is these gems are becoming rarer and more valuable.

National Gemstone presently has one two carat 2.5 AGL color on our web site:

2.23 "Classic" Mogok Unheated Burma Ruby
