aquamarine – Shigar, Pakistan.  Fabulous all natural geologic process etched double-terminated blue-green beryl with shimmering muscovite and abundant allure. Peeking through the window into the interior and wondering about the perfect sea-like world that lay within is the reason that I’ve held onto this so long. I always wondered, and still do, what sort of huge stone or pair of stones you could cut from it and what the sea green gems would look like. Although it looks rough, it’s amazingly perfect. The interior appears to be clean and without any fracturing, probably some natural veils. 7 cm long; about 42 mm thick at widest point; just under 7 ounces.  $900
