And now for something completely different. What I want to show you is a very rare geological freak of nature.
The photos are of a natural, unheated, untreated sapphire from Mogok, Burma. I bought this stone some years ago and keep it in my collection. Gem photography is notoriously difficult dealing with the effects of light in a 3 dimensional object. Reflection, refraction, dispersion, saturation and angle of incidence. Mogok produces the finest Ruby and Sapphire in the world. Always has. Gems have been mined there since antiquity and were mentioned by Marco Polo in his "Travels" 800 years ago. Paleolithic tools have been found there. A natural untreated Mogok Ruby of 7.04 carats just sold in Hong Hong for $2,979,128 U.S Dollars, or 430,000 Dollars per carat. Whoa.
