I discuss new ways to grow diamond that promise near-deterministic design of fluorescent color-centers, optimized for quantum sensing applications. Briefly diamonds are grown around diamond-like organic seed molecules that have the dopant atoms needed for specific color centers, located in the correct approximate locations. It can be seen that this approach can give unprecedented control over the number and placement of color centers. Complete quantum registers might also be fabricated, for example a nitrogen-vacancy and at 13C atom with a well-defined separation surrounded by only 12C diamond. In this talk I will discuss our first key success, which is growing diamonds under conditions where the seed molecules are stable, as well as current experiments.
