My Special Object

My object is blue, gold, pink as every time as a sparkle of white appears my eyes must blink.
The trinket holds my favourite chocolate as every winter they turn rock hard…
My trinket can hold bits and bobs, so every time when i open the box I always see little shards of rocks…
It was only until I found this trinket in universal studios…
I had to pick the most beautiful one…
Only now my trinket is sitting at the edge of the room, it will only be a couple of years until it is time for doom…
