We’re life-long tinkerers, siblings, and fourth generation engineers. We’re not quite sure which of us had the idea of putting LED’s on jewelry and powering them with solar cells, but once Marty proved it could be done there was no stopping us. That idea became Lumen Electronic Jewelry. Marty is now the Chief Geek, Robin is the Design Diva.

The parts you've chosen should work great. One thing to keep in mind is that the rated power of the AM-1454CA solar cell is given under bright indoor lighting. It will produce a lot more current and a bit higher voltage when exposed to direct sunlight. Similarly, the blue LED will show some light at even 2.2 volts, well below the usual rated forward voltage of 2.7-3.0 volts. (the I vs V curve in that's often in the data-sheet shows this)
