It was Rocks & Co selling it as Zultanite, I know because I bought myself a ring as a special treat for my 50th birthday. I wore it everywhere, in all kinds of climates, heat, cold, candlelight you name it and I wore it. I have still to see the colour change in the way we are told it will change. It looked a pale kiwi green when I bought it and I've never even seen a hint of change to the colour yet. It may be the cut of mine (emerald cut) is not a good cut for colour change or it could be that it was just more BS and I fell for it.Yes, and not only that, but Gemporia used to say (they may even still do) that they were 'the only seller in the UK selling Csarite' - but that was complete BS because TJC were also selling it (under the name 'Zultanite' if I recall), and another UK seller was selling it under the name 'Turkizite'.
They may have been the only ones selling it under the name of 'Csarite', but they were definitely not the only UK seller selling that stone!
Misleading at best. Obtaining money by deception at worst!
