Coster Diamonds disgusting place! The staff have NO MANNERS, the main goal is profit !!! I was with a group of 5 people locked in a room and we has been told that as long as we do not buy, we would not able to leave the show room !!!! And they kept us locked up for about an hour, when we were already late for a ride on the boat, and our indignation there was no reaction from the staff.
The "professional" staff call Diamonds as a pieces of glass and black Diamonds as a coal !!!!! What is this????
The collection of jewellery does not beautiful at all!!! It is raw and ugly!! In one ring there was NO STONE !!!! And this is one of the famous factory with a name???
Do not waste your time, there are a lot of other good places in Amsterdam!
