Change Silver Jewellery to gold

[JoeIXn]

For GIMP I’ve had some luck using colorize on a masked layer, then playing with hue and saturation until the silver warms up into a gold tone. Adding a bit of brightness/contrast makes it look less flat too. Took me a while to get it right when editing photos of some wedding bands for women I was browsing — the lighter shades leaned yellow too fast, so layering adjustments really helped.
