Jewelers in many parts of the world now use gold solders, which are free from Cadmium. Please note that the wearer of the gold jewelry is not harmed, this issue only concerns the manufacturing process. Also note that using any type of gold solder either KDM (Cadmium) or other gold solder, to make the jewelry does not guarantee the purity of gold, as the purity is a representation of the percentage of gold in any metal.

and also it causes skin problem to the person wearing it. If anybody after wearing chain of 916 KDM quality find their skin darkened or itching around neck please change to copper soldered one. cadmium is skin allergic though ure not hypersensitive it may cause allergy in a long run.

Is 91 6 marked gold different from the 916 "KDM" jewelery? Or are they the same? I recently bought a simple pair of studs which just says 916.

Thanks,

Hi,

916 simply means it is 91.6% pure gold that is instead of 24 c it is 22 c (91% of that) KDM is just a soldering material for joining pieces

Hope it clears
