Yes. Blue LED's exists, and are made by Siemen's Optoelectronics. They come
in a stantard T1-3/4 package, and are packaged in CLEAR plastic. The forward
voltage drop is ~4V. When I called Siemen's to ask for a sample, they told
me they cost ~$50.00! They are made from silicon carbide, and emit light
at 420 nm. (I am not sure about the wavelength. This is all from memory.)
If you want to call Seimen's about them, the part number is:
LDB 5410
Good luck getting one.
