My first post here...

I am a jeweller and post pics of the jewellery i make on my website, ebay etsy etc.

I have had some success with changing the colours of stones using gimp... garnet to Amethst, sapphire , Rubt etc.

But I'm trying to work out how to change silver jewellery into gold.

If anyone can point me to a tutorial I would be grateful.

Here is a photoshop tutorial.. I need the same thing for GIMP

Yes that really looks ethical.

• Sample the color in some good part with the color picker
  
• Make a selection on the area you want to cover up
  
• Create a new layer
  
• Bucket-fill the selection with the sampled color
  
• Set the layer to blend mode HSL Color, LCH Color or, if the covered part is a sufficiently neutral grya, Multiply.
  
• Adjust opacity to taste.
  

Another way but it depends on separating the ring from the background which is a whole different matter.

If the ring is already silver color then it can be colourised. To make it more "metallic" a Colors -> Curves adjustment.

Thank you... going to play with separating the rings from their backgrounds... and then playing with colour curves.
