Hi Tiffany thanks for introducing yourself!!! Agree with Ed nice semps!
My approach to your situation is to label the semps you think are Cavo Doro, with the name then a question mark then see if they match up to what else you have that is Cavo Doro and wait and see... It isn't a semp I own so don't know what it looks like and if giving or selling I'd keep it labeled as a NOID, this stops any mis identified semps being out there...i have lots of NOIDs!
