The Diamond Cocktail
As from 1991 Diamond House has been the host of many occasions where it served the 'Diamond Cocktail'.
A Diamond Cocktail is a glass of champagne in which a little three mm. brilliant cut stone has been put into. Most of them of course are Cubic Zirconia's but according to the clients assignment, there are some that are genuine diamonds.
On the glass is attached a little gold cord with a card that says: 'Let's drink to a sparkling future, but...drink with care. Each glass contains a diamond, or is it a fake?'
Upon serving the Diamond Cocktail, each guest has of course been informed about the nature of this event. This to prevent anyone from swallowing the diamond...
As the evening proceeds and everyone has spoken about the originality of this incentive, one of our experts slowly starts to mingle in the crowd to check each little 'stone' using his diamond loupe. He alone can distinguish a diamond from a Cubic Zirconia's just by using this diamond loupe.
Many so called diamond companies have since copied this idea but none as far as I have heard use this expert technique.
Their way of telling a diamond from a Cubic Zirconia's is to weigh it on a scale (different mass) or the card attached to the glass has been 'signed' discretely ... Anyone can do this.
An idea? Switching cards will not work at my Diamond Cocktail, but it is a nice try to fool the fancy expert!
