Ruby - Thai and Burma


#
The 1.33 is a no heat "Classic" Mogok Burmese ruby. It grades 4.5/65. This color/tone is known in the trade as "electric magenta". These are fluorescent gems are primarily red (60% red) but not pigeon blood or stoplight (70% red). Due to the light 65 tone it never blacks-out and looks great in all lights. The clarity is perfect at (FI) free of inclusions. How many FI Burma rubies have we seen over the years? You can count them on one hand and this is the only one we are aware presently on the market. Good luck finding another with AGL grading. The only negative of the stone is it has a 40% brilliancy. If you mount the stone, a top jeweler can visually close the window. On the other hand, the collector owned this stone for 22 years "as is". The Total Quality Integration (TQIR) is Very Good or 3.5. If you always want a Free of Inclusions(FI) Burma ruby, this might be your last chance. A super rare gemstone for any gem portfolio or to mount in an upscale jewelry piece.

A snappy, red gemstone with desirable light tone. The stone is also extremely clean at LI2 clarity. The gem has no brown or gray in the color scan like many Mong Hsu rubies. Lights up exactly like the Mogok material in a fluorescent box. An inexpensive alternative for someone who wants a red Burma but wants a serious discount to the Mogok material. You could also mount this stone in jewelry and no one would ever know it's heated.

This stone was resubmitted to the AGL in 2018. The two grading reports are pretty similar except the Total Quality Index Rating (TQIR) went from Very Good to Excellent in the new report. The report also confirmed the stone as Classic Burma, which was probably left off mistakenly in the first report. See new report below.

The stone is a perfect 75 tone and never blacks-out and looks red in all lights. The clarity is LI2 means you cannot see any inclusions with your eyes. These factors make this stone desirable. The stone has typical Burmese cutting and a 50-60% brilliancy. A serious gemstone for a portfolio or to mount in an upscale jewelry piece.
