Those are ice cubes on glass table in my room.
I've used Lumia 1020 DNG file cropped and heavily processed in Lightroom 4.
Camera flash wasn't used for direct lighting - it was blocked with tin foil and served only as a remote trigger. Lighting was done with two Metz 58 AF-2 flashes set at 1/256 power, zoom 35mm with CTB filters, both placed on table about 1 meter from cubes.
