==Early career== Called the "Dutch – Indonesian Everly Brothers", the Blue Diamonds covered many Everly Brothers songs, but became famous in 1960 with their version of "Ramona", a song originally written for the 1928 film, ''Ramona''. The song was written for promotional appearances with Dolores del Río (star of the film) but not featured in the film itself. The Blue Diamonds up-tempo version of it (changing it from the original {{music|time|3|4}} rhythm to a {{music|time|4|4}} one) reached the American ''Billboard'' Hot 100 at number 72 in 1960. It sold over 250,000 copies in the Netherlands (the first record to ever do so) and over one million copies in Germany by 1961.<ref name="The Book of Golden Discs">{{cite book | first= Joseph | last= Murrells | year= 1978 | title= The Book of Golden Discs | edition= 2nd | publisher= Barrie and Jenkins Ltd | location= London | page= [https://archive.org/details/bookofgoldendisc00murr/page/121 121] | isbn= 0-214-20512-6 | url-access= registration | url= https://archive.org/details/bookofgoldendisc00murr/page/121 }}</ref>

A couple from Driebergen-Rijsenburg has taken the initiative to erect a statue to commemorate The Blue Diamonds. In mid-October 2025—65 years after Ramona became a global hit—the statue of the singing duo was unveiled at the Oranjevijver in their former hometown. The moment received national media attention.
