Since I want to promote pearls of all kinds, I never hesitate to wear my larger pearls for every day. Personally I do understand that it is expensive to get Freshadamas larger than 8 - 9 mm, but this size is not sooo large that it would be disturbing to be seen on you..
Go for coloured if you think they are more casual - on the other hand there are so many consumers out there, having no knowledge about pearls whatsoever and they just might think you coloured pearls are fakes but perhaps think of white pearls as being the real thing - and what nicer than a fine freshwater strand to prove to all people how far industry got in getting such quality out of our common mussels!
