While filters alone are not a definitive test, they can be very helpful. They don't tell you what something IS, rather what something IS NOT. By the way, there are bigger photos of the reactions on the website and I will be adding more. Please share your photos, too!
Filters can help distinguish between dyed and natural jade.
They can also help quickly sort stones when buying a lot. Say you are buying a lot of tsavorite garnet, you can use a filter to do a quick check to see if they are all at least giving you the same red reaction under the filter. If they don't, that's a heads up that some of the stones maybe something else. In the example photo above, I added some green tourmaline to a lot of tsavorites. As you can see, under the filter the tsavorite reacts red, while the tourmalines are showing the blue of the filter. Again, not a guarantee that the stones that react red are tsavorites, but at least you know the ones that don't, are not. Pretty cool, eh?
You can find the jadeite filter HERE.
