I forgot to add Baikalla! They are based in the US. I think their prices are a bit high for the quality though.I think I was reading the forums here about reputable sellers. I am by no means an experienced buyer, so please do your due diligence! The first bangle I bought was from Kathy Jade. They have a lifetime 10X money back guarantee if it’s ever tested to not be grade A jadeite. The next two bangles I have coming are from Ultimate Jadeite. They also have a money back guarantee and a storefront in Singapore. I am not in Asia.
Matsalicejade and all about jade Canada seem like reputable sellers as well. I learned that I will not buy from anyone who doesn’t have a 100% money back guarantee if it’s ever tested to not be grade A jadeite but any of these shops could be fly by night if they wanted.
Maybe check out Eastwind Jade on Etsy. They made it on the reputable sellers list here. I recently started browsing WaterCrystalJade on Etsy too but haven’t purchased anything. Just ogling lol.
