Old China Patterns?

HI girlies
I am lucky and my Grandma gave me her china! Yay! but i was wondering if there was a site or store where I could order missing pieces like a tea cup that cracked.
If anyone knows of a good source for discontinued China please let me know!
FYI its Rosenthal and the pattern is Colonnade- thanks ladies

i tried- they dont have the pattern :(
that was the first place i looked b.c I love ebay!

try replacements.com

my friend used them b/c she broke a piece of china her landlords lent her and she had to replace it really quick.

I hope this site is useful and it has your pattern. Will you let me know?

I did a search for you on replacements.com and they have your pattern! They have the cup! Yippee!
