My 18" old stamp Istanbul K cymbal before:
After:
Repaired by laser microfusion by Jake Winebrenner in 2015. Cost depends on the amount of time involved and how complex the cracks are. I think the usual fee is about $40 (plus shipping) but you should check with him. In the after photo the pencil points to an area where there was a "hanging chad".

I'll have his email address lurking somewhere on my disk, or if you do Facebook there is a link to him below the video.
