Here's some coloured fire from my new 1.8ct Namibian demantoid garnet halo ring I love the rainbow whisp rising off it at the 2 o'clock position in the first pic. The centre stone is bezelled in rose gold to play up the blue/green colour.
Strangely, I can never capture the fire from my diamond jewelry on camera, but I managed to get a photo of some sparkles from my new tourmaline ring.. it sparkles like crazy in the sunlight!
