Learn everything about ‘a girl’s best friend’ in this family-owned diamond factory where you can take a free tour of the premises in dozens of different languages and buy something bright and sparkly for your significant other in one of its showrooms. Although you’re by no means obligated to purchase anything, we recommend a visit to any young man who plans on buying an engagement ring at some point in his life. They’ll teach you about the four ‘Cs’ – colour, clarity, carat and cut – and how to spot a fake so you don’t get ripped off elsewhere. Watch diamond cutters and polishers ply their trade and finish your experience with a complimentary cup of coffee or tea and a Dutch cookie at its Delftware shop next door.
