Radical new treatment methods use chemicals such as beryllium to create colour artificially - even in blue sapphire now. So how can you be sure you are buying natural gems ? Only by purchasing direct from the source. Increasing misrepresentation of synthetics, chemically altered or irradiated gems as natural hurts the buyer. Sometimes even experienced dealers can be fooled & may sell these on to unsuspecting customers who think they are getting a bargain.
If you want real value which will increase over time, insist on signed guarantee of origin and treatment status. This is provided for all gems from our own mine.
