Could anyone tell me if Asteriated (asterism) it makes the gemstones more expensive and valuable? or not. For example ..sapphire starr and ruby starr is most expensive than sapphire and ruby stone gem?

Yes it does at some point. I do believe that a very high quality star ruby or sapphire in small sizes surpasses a high quality ruby or sapphire, but on bigger sizes rubies def are more expensive.

I have in my possession numerous diasterated star apatites with well defined 6-rayed the stars only appearing in transmitted light, however, Unfortunately though, it is rather difficult to illuminate such stones when compared to a typical star stone, these stars only becomes sharply apparent when lit from behind, and, in general these stones show no epiasterism. I would argue that this phenomena may not be as rare as could be assumed by it's lack of discussion, and, as such many potential star stones may exist of this type, particularly in golden apatites from Durango as we're those I've encountered, and, most likely these potential star stones might have been overlooked due to the tendency to facet such apatites rather than cabbing, and, of those that have been cabbed appropriately, such stones may have not been observed under the necessary lighting conditions to display the phenomena.
