Deletion of The Natural Sapphire Company

Comment: I work in the jewelry industry as well.  This company is very famous for their collection of sapphires (which is said to be the largest collection in the world).  If this doesn't make them notable, what does? Also,  as stated on top of that page, is NOT set in stone. It's easy to research this company on the internet.  There are many articles and forum posts

Comment: I did a bit of cleanup on this article without really looking at the sources/references. I should have done so. Of the references, one is a press release from the company; one is a blog post commenting on the press release; one is an article which does not mention the company concerned except in a comment at the end, which could have been added by anyone. None of those qualifies as a |reliable source
