This is the single best specimen I've seen with both quality, well formed crystals and good color. The main crystal is 4.1cm wide and displays a satiny blue color across the end surfaces. This 'Schiller effect' is seen when you turn the crystal under lighting. Good color can be seen on a number of the other smaller crystals too. Moonstone crystals are rare!
