This is an exquisite little specimen. A cluster of brilliantly-lustrous aegirine crystals is perched upon white microcline – they look black, but upon close inspection under strong light one can see that they are the darkest green. The main aegirine is doubly-terminated. In excellent condition, these cystals are pristine, except for one tiny chip on the left crystal and a small chip at the back of the specimen. Stands perfectly for display as photographed. This one is really super.
