with increased use of very high performance DDS and PLLs, the precise 
frequency may not be as important as it was when you were limited to 
straight up multiplication/mixing synthesis.

I suspect that a "10 MHz +/- 100kHz" might be a higher yield requirement 
than 10 MHz +/- 1ppm or +/- 1 ppb.

You could focus more on aging behavior.

But, small "tooth sized" pieces - how big is your crystal.
