Diamelle Diamond Simulant: What Is It & Its Value?

Question
I have an 'authenticated' 1/2 carat Diamelle.
What do I really have?  And is it worth anything?

Answer
HI JERRY,

'DIAMELLE' IS ONLY A TRADE NAME. IT IS NOT AN IDENTIFIED SYNTHETIC OR NATURAL MINERAL, IT IS MOST LIKELY CUBIC ZIRCONIUM (CZ). IT IS A DIAMOND SIMULANT NOT A SYNTHETIC DIAMOND BUT A STONE MADE BY MAN TO IMITATE A DIAMOND. THERE ARE DIFFERENT GRADES OF CZ AND THEY COME IN A WIDE RANGE OF PRICES. THE MOST EXPENSIVE AS HIGH AS $25/CT AND LOWEST BEING AROUN $1/CT. THE COMPANY MARKETING THE 'DIAMELLE' CAN SAY IT IS 'AUTHENTICATED' JUST BECAUSE THEY SAY SO. IF IT IS IN A GOLD RING THE RING IS USUALLY WORTH MORE THAN THE STONE.
