KDM: Gold Jewelry from some places is / was marked with a KDM stamp which means that the Jewelry was soldered with Cadmium. Cadmium called 'Kadium' in some places and marked KDM was traditionally used in soldering of gold jewelry for its good properties of liquidity and melting at lower temperatures, which is not the case any more as Cadmium is known to create toxic fumes when melted, which are very dangerous to health, over a period of time and may be harmful to humans, making the gold jewelry.

The price of gold changes even in seconds so it is hardly to fix the rate in this answer for the future.
916 means How much of purity in your gold thats says in % . For an example. The pure gold is 24 carrot. We can't make any ornaments with pure gold. So the gold Smith add some percentage of copper to make ornaments. While you add copper the gold purity will be come less carrot. While we purchase 22 carrot gold ornaments that mean 22 carroty divide by 24 carrot the answer will be comes .916. That means in 1000 particle of gold added 84 particle of copper mixed and made ornaments. 1000/84 equal 916. 916 mean 22 carrots. 875 means 21 carrots, 750 means 18 carrots. The amount of copper mixed with your gold. The kdm is the shortform of kadmium. This cadmium chamical will help to join the ornaments and will get evaporate and will not stay with gold . Before cadmium technology Gold Smith are using powder flex to soldering the ornament and the powder flex wax will remain with gold weight. Hope you understand now with nannees Coolmeerawahab.
