Which Gemstone Filter Should I Buy?

The title says it all. Which Gemstone Filter should I purchase, a Jadeite, Chelsea, or Tanzanite? Or do I need them all?All very important questions! First off, let me say that you need which ever you can get for the best price!! Once you purchase one of them you will NOT need the others!! Why you ask!? Well, let me tell you; The reason you only need one of them is because they are all the same exact filter!! Don't be fooled into buying them all or thinking you need them all! They are the same filter bearing different names for marketing purposes!I know this Guide is quite short, but I think it covers an issue or gimmick that many purchasers fall into!Please do not forget to vote.
