Consumers who plan to purchase fine blue moonstones might have to delay their plans indefinitely now that the world’s main vein for this gem in Sri Lanka has run bone dry.

Alas, it shows what is probably a nearly, if not already, extinct variety of this gem that many Europeans, principally Germans, often found lovely enough to encircle with diamonds.
