    Hello, I have refered all the literature we have at the college
    platinum is not affected by hydrflouric acid. It dissolves in
    aquaregia. you may try removing the coating on the diamonds by
    applying aquaregia selectively on the coated diamonds. you would have
    to do it under a fume cupboard or a well ventilated area. 

Best regards,
Umesh
