I am, but I try to make sure people don't know it. It seems to make them nervous that I know all their secrets.

If the rhombus has sides of length $a$ and $\theta$ is one of its interior angles, the diagonals have lengths $2a\cos{\frac{\theta}{2}}$ and $2a\sin{\frac{\theta}{2}}$. The two are equal if and only if $\theta=\frac{\pi}{2}$.
