I don't have the pendant, just this image of it.
Backstory : couple of months ago I ordered a mint green to teal colour Montana sapphire pendant from a reputable jeweller I've worked with previously. Order was confirmed and details discussed via email and images of suitable stones for me to choose from were to follow. But no images were sent and last week when I enquired about the stone selection for my pendant order they replied after a few days with this photo of the blue stone pendant and I was told it was ready to ship.
So I'm kind of annoyed and unsure how to deal. Not helped by my inexperience with Montana sapphires and that I'm in Australia and jeweller is in the US. I think I may have to call them for a chat.
Any further thoughts or advice very welcome !
