Long story short: i'd like to get a Muzo emerald to make a ring for my birthday (2000 to 3000 per carat is my little budget). I am in contact with some IG sellers. The confusing part is that, the emerald color looks different under different lighting and with/without settings. It's a bit challenging for me to tell (w/o seeing them in person) which would be the one. 
Said that. has anyone got emeralds from IG: gemfactor_emeralds? they are in Switzerland and quite responsive and stones come with GRS certification but price might be slightly higher than IG: muzoemeralds (George Smith). George is responsive as well. His stones only have local certs and everything seems to get "vivid green" which I think for GRS standards, they may just be "green". I am more inclined to get the stone and do the setting locally (I am in the US) because I am afraid if there is any issue with the stone and it's already set, it won't be returnable. Please share your experience if you have purchased with any of them or stones from other sellers remotely. Except video clips and certs, what else would you look at before buying?
