My Mother recently bought an Emerald whilst on holiday in India. The stone has been set. Only problem is it looks like it's clear in places and green in others, a bit like if you dropped green dye into water and it forms coloured clouds. I know of cloudy Emeralds, and this looks nothing like one. I will post a picture as soon as I can.
Emeralds often have flaws and appear cloudy. Please post some pictures so we can take a look...
i got an emerald suposedly, and it discolorated later, just like you say, like if it was bleached. I believe is fake, Anyone?
Emeralds are durable and have stable color. Color discoloration is likely a sign of artificial coloration.
