Actinolite is definitely a collector's gem - There are very few faceted gems in this material and gems over 2cts are listed as some of the largest known.  This gem is quite difficult to facet - facets can fray on sharp edges and there are 2 very easy cleavage planes; it polishes OK if not done parallel with the cleavage planes!  The Actinolite group of magnesium-iron gems also includes Tremolite and Smaragdite.  Tremolite is Actinolite that contains more magnesium.  Smaragdite is the variety of Tremolite containing Chromium.  We are please to offer the following very large clean Tanzanian crystals below (Tanzania is one of the few locations that facet grade Actinolite crystals are found) :

Note:
This material is not commonly available - we have not seen any of this quality offered in 5 years !  These stones are all very clean at 10X and unusually large sized for this material.  All stones are a sage-green/olive-green color on the main cutting axis and yellowish down the c-axis. And if you are successful in faceting one of these large clean stones you will have a world-class sized gem.
