Getting more and more popular now this ring is made from 950 Palladium and new precious metal. Palladium is nor great for working with if you need to join it. For example on a re-size with cut you will get a black line showing the split. Overtime we have worked out the best way to deal with this is to score the "show" and fill it with a thin piece of wire using a lazer welder. 
This was made for a local customer and has been resized once.
