Gold on green...an experiment with photography

I shot few frames last week: the subjects were few bangles and a ring that my mom usually wears.

I considered two set of lighting for the shots.First, I considered white lighting and switched on all the fluorescent tune lights in the hall. For the yellow lighting, I switched on the lamps in the hall.

Few shots are listed below:
Exposure was set for 8 seconds for the first shot, 2.5 seconds for the next 2 shots and 5 seconds for the last 4 shots.
