Beamer: use Frankfurt theme blocks with default theme

Question

I'm using the default Beamer theme because I like how it looks with the beaver color theme. However, the only thing I don't like about it is that blocks do not have a box around them. I like the block style from the Frankfurt theme, but I don't quite want to use the whole Frankfurt theme as it changes some things I like about the default theme.

Is there any way I could use the Frankfurt theme for just blocks, and keep using the default theme for everything else?

Thank you.

If you just want the blocks in the same colour as with Frankfurt, you could use the orchid colour theme in addition.

If the blocks should also have the same shape, add \useinnertheme{rounded}.

\documentclass{beamer}

\usecolortheme{beaver}
\usecolortheme{orchid}

\begin{document}

\begin{frame}
    \begin{block}{title}
    content...
    \end{block}
\end{frame} 

\end{document}
