ENORMOUS 15.97 carat, deep blue natural, unheated, Brazilian Aquamarine gem!

I have been a gemologist, lapidary, jewelry designer and manufacturer for over 5 decades. Today, I am proud to announce that I will be selling some of my "Cream of the Crop" gemstones, gleaned from a lifetime of collecting. These are the exceptional gems that "I was going to make a mounting for - someday." My 76th Birthday has passed, and, while I am still in very good health and condition for such an old fart, I can see that I'm simply not going to be able to give all of these fine, rare gems the attention they deserve, so I am offering these exceptional examples for sale. Brazil produces some of the world’s finest Aquamarines – and this beautiful, 100 percent natural, 15.97 carat gem is one of them! Most aquamarine that comes out of the ground is so pastel that the blue can barely be discerned, and when it can be discerned, there is often a distinct green tint to the gem, in which case the stone must be carefully heated to remove the green tint. This stone represents a double whammy of goodness. It has a naturally occurring rich blue color with only the very slightest hint of green. It has not been heat treated in any way. After purchase, and by special arrangement, this outstanding gem can be mounted in the metal of your choice – even platinum – by award-winning designer and jeweler Mani Pureheart! All of my faceted gems are guaranteed to be genuine, natural gemstones. I offer a 1-week-from-delivery refund if they are found not to be genuine.
