1.02 No Heat Burma Ruby

This is a new 1.02 no heat Burmese ruby. It grades 2/80. This color/tone is known in the trade as pigeon blood or stoplight red. The tone is medium dark at 80 (Ideal tone for ruby is 65-85). At Sotheby's in October, 2020 a 6.41 Burma ruby sold for over $432,000 per carat. It was a 2.5 color so the 1.02 is probably redder. AGL has stopped putting color scans on their grading reports, as they transition to a new system. However, we can deduce this stone is at least 70% red or 75% red. A true gem vivid red stone. The clarity is MI1. It's you look really hard you can see an inclusion but don't forget, this is how the lab proves no heat and Burma provenance. The cutting and finish are typical for stones cut in Burma. AGL calls the cutting and finish good. We have to remember, the cutters are ordered to save weight when polishing these stones. If cut perfectly, this stone would be a sub-one carat and the cutter would be fired or worse. AGL states the average brilliancy is 50%-60%. It looks a little higher to our eyes. The Total Quality Integration (TQIR) is Excellent or 1.5. This is the overall grade of the stone and Excellent TQIR's are rare rare. Obviously, the AGL has a high opinion of the stone. A serious gemstone for a portfolio or to mount in an upscale jewelry piece.
