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 PG stands for Plated Gold - meaning the ring is not pure 14kt gold but made of another metal overlayed with 14kt gold
"pg" on a necklace, ring ect. stands for plated gold ; meaning the jewelry is not completely gold, its a different gold with 14k plated over it.
"GE" stands for gold electroplate, meaning that it may not be a true gold ring. Have a licensed jeweler make that determination to be certain.
The meaning of 14kt ge is 14 karat gold electroplated. It means gold is plated over a base metal of some kind other than precious.
Karat (K) is the number of parts, by weight, of gold. The higher the percentage of pure gold, the higher the karat. For e.g., 14 karat gold is 58% gold, 18 karat gold is 75% gold and 24k gold is pure. 22k gold is 91.67% gold.

how can i convert my kdm gold jewellary to hallmark jewellary
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.
The difference between the two types of gold is KDM is mixed with Cadmium which is harmful for human skin. Hallmark gold is pure gold and follows the Indian standard specifications.
