    The colour says peridot/olivine, but the cloudiness says emerald. If its not those it's aqua. That's my scatter gun approach. It would make a super mini pendant.

    OK let see what you guys make of this one? I'll add clues as we go along.

    Tip: it's meant to deceive !

    Now who was it was pointing out that visual appearance isn't a reliable indicator of the stone?

    Colour tone looks wrong for a sapphire variant (or the ones I've seen), could be a CZ, could be a topaz (although I think there's a slight green tone in there that again I haven't seen in topaz), diamond...?

    I could not agree more, it goes against my gemological brain. That said the first step in identification is visual inspection.

    sapphire can be any color except red (red sapphire is called ruby!) but its not one - that would be too easy

    It cant be a diamond, there is a shadow in the pavilion (red arrow) a diamond would not do this unless very badly cut or very very small, CZ and Topaz will show this affect

    I'll rule out topaz

    The purple arrow is the second clue , and why it's not (likely) CZ, and unlikely to be Topaz;

    I so do not know what to do with it. I have had it for three years and it keeps on appearing - I do have some gold now that I could use to do a micro pendant........... but all those angles, I am afraid I will break it!

    Sorry,Alexandrite should turn from green to red, "lab Alexandrite" which normally is synthetic carborundum (sapphire) can be blueish. Like emerald, even the best natural Alexandrite has loop visible inclusions, which in fact contribute to the color change affect. this stone is too clean.

    Oh go on, it isn't every day you get to use the word pleochroism...

    When you mentioned the shadow on the pavillion, were you meaning that with a brilliant cut it should throw light from that surface as readily as the rest?
