Holy shit, how did I not spot this before? I should browse the marketplace section more often but it's usually only spammers that get to the top, I'll keep you in mind as well as that Gemvault guy if I'm looking for anything in particular, right now I don't have the money to regularly afford stones like that though.
For others, he's taken some very good photos, they don't look like cubic zirconia from what I can see, otherwise they'd be too shiny etc. and look too 'perfect' which are usually the main signs of an artificial stone.
Thank you for the kind words and especially for being generous on the quality of my photos. They are getting better but are definitely not where I would like them to be. I try to provide as good a look as possible.
The important thing is as you mentioned, these are natural stones not synthetic or artificial. Everyone who has ever purchased stones from me has been very happy with what they receive.
More stones will be posted shortly.
