Looking for Ceramic knife sharpener.

[Matilda]

Just got a 7" Ceramic Knife. (Zirconium Oxide). Have been trying to find a sharpener for this knife. Everything I've looked at shows pictures of a Steel knife being used, or else the sharpener mentions "Coarse, fine, honing. I've read I need a diamond sharpener for Ceramic, but unless I spend over $50 I can't find one cheap enough.
Anyone have any ideas?
Thanks
