I have photographed a coloured glass bottle under different lighting set-ups in the studio.
.
The following are lit by:
.
Honeycomb on right side and slightly above subject

This gave a rich colour to the glass and good highlights but had stong shadows and reflection of the light in the bottle.
.
Softbox (masked) on right side and slightly above subject
Bright glass and soft shadow but weak detail and very harsh highlights and reflections.
.
2 Soft boxes (masked), one on each side and both slightly above subject
