The termination of this Stak Nala termination is just astonishing in person. It is from a rare find in 1997 - 1998 with light blue "caps" - and you can see here, it changes abruptly from a grass green to a light sky blue. There is a sidecar crystal as well (nicely terminated, like the main crystal) that is blue through the top half, green through the bottom. Weighs 39 grams.
