I'm quite enjoying making these test tube based LED lamps, so this one is a super simple resistive dropper version with two 100K resistors, a discrete bridge rectifier and 14 LEDs in series.
I used a mixture of green and blue LEDs with their lens tips chopped off to give the cracked ice effect, and a single straw hat "pink" (magenta) LED at the end.
It's designed to be decorative only, so runs at the very low power of just quarter of a watt.
