Well. That is a good question. Rainbow Calsilica is it real or not? It is most definitely real as in a real material fashioned into slabs and cabochons.
But the source of this material is man-made without any doubts nor questions!

I have been reading so much on this topic as of late, and debated not even touching it on a personal note, but have decided the need to do so anyways.
First off, there seems to be two sides to this debate/debacle, those in the Industry who are either turning a blind eye and/or screaming everywhere and anywhere they can to deny the diffusion treatments of garnet, tourmaline, and other gemstones. Some of these are big Industry names, like some well known bloggers… writers.. labs, for example, and some are nobodies trying to become somebody. This group has not provided ANY research support or proof to back up their claims that these new treatments do NOT exist. They have not done any research at all into the matter either. They just sit behind a computer and type insults on blogs directed towards those who are actually diving in head first and doing the research to uncover exactly what is going on with these gemstones. Keep in mind that this group contains mot of the same persons that were on this side of the great Andesine debate and debacle, and, were wrong then as well! Many of the persons in this group have a lot riding on these treatments remaining hidden and undisclosed to the general public because it would severely impact sales as well as cause many refunds and returns as well as even tarnish some reputations. Whilst this is understandable, wanting to protect livelihoods and professional standings and reputations, it is inexcusable to do so on the backs of the unknowing consumers!
NEW YORK – (December 1, 2008) Yehuda Diamonds filed a federal lawsuit seeking to require Blue Nile, Inc., which claims to be the world’s largest online retailer of certified diamonds and fine jewelry, to offer a full and complete refund to any Blue Nile customers who wish to return emeralds or emerald jewelry items purchased from the company. The complaint, “Diascience Corp. dba Yehuda Diamond Company and John Does. nos. 1-10, vs. Blue Nile Inc.,” was filed November 12 in U.S. District Court for the Southern District of New York (Court Case #08CV9751). Blue Nile shares are listed on the NASDAQ under the ticker symbol NILE.
