Hallmark Gold KDM Gold

Hallmark Gold KDM Gold 
What is KDM means:
Without soldering hadrly to make jewel so make jewel easy.solder should have a melting temperature lower than that of gold, so just the solder melts and joins gold pieces without affecting the gold parts.In this solder was combination of gold and copper since it allows strong and make easy jewel,this is traditional method to make jewelry.There is no particular ratio for this solder.The purity of solder is very less about 60% or 70%near to22karat gold.For this reason to maintain gold purity instead of copper starting to used cadmium.In solder they used gold 92%,8%cadmium that means solder itself have purity.Such jewellery using cadmium began to be widely known as KDM jewellery.But shortly after the introduction of cadmium, it was banned by BIS as it was found to cause health issues for artisans working with it. After the ban, cadmium was replaced by advanced solders with Zinc and other metals. But the term “KDM” hung on and is still commonly used. So a KDM jewellery means it will have the same purity even when it is melted, as the solder itself has a purity of 92%.
KDM-marked jewellery was banned in many countries. KDM does not stand for quality. 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. KDM mark is a “statutory warning” against use of jewellery made with cadmium soldering. However, the jewellers often advertise KDM as a quality-mark and sell the jewels at a premium.
