Natural Certified Untreated Sapphire., 17.02ct. (Y45)   

A gorgeous cushion cut that has a step cut pavilion and a radiant crown.  Measurements on stones of this high quality are always odd.  The rough is so rare the cutter needs to remove as little as possible to preserve the weight of the stone.  A radiant bottom would squander too much of the stone.  This is a huge and very good stone for your collection.

This stone caught my eye as it appears to be very well cut and eye clean.  It has been heat treated and is a beautiful pigeon blood color.  The owner wants to be contacted for further details.  A little disappointing as I would like to tell you more about it.  The pigeon blood color is famous in the world of rubies.  L 9.69 mm x W 7.51 mm x H 5.79 mm.    Sure looks great from here.  $ 105, 600   http://amzn.to/2qG7CdB
