Don't know whether to say congratulations or send my condolences to saying goodbye to the last of your collection!?!

The NOS Escher Blue/Green, still in it's wooden box, with the Gold Seal stamped on the stone, still sits untouched, with the labels now preserved with Artists Varnish, both stones then wrapped in cellophane, and the box itself stored in an air tight Zip-Lock bag with a desiccant pack.

Again, thank-you for such a lovely stone.....
