Which cheap imitation jewelry is that, Mukesh? Sold from the back of a truck or at a bazaar or by Nordstrom's? Rings, earrings, necklaces, naval piercings? Approved for sale in which countries? I think you need to be a little clearer what items you are wondering about. Thanks!

Hello Sir,
At Hyderabad (Charminar) many jewelers sell ERs, NKs, chains, Bracelets, etc for 0.25-0.75 dollar(15 to 30Rs) which is very cheap, and are long lasting for more than 6months, I am making jewelry on tin alloy which hardly last not more than one week, although I use Degussas bath and 24k color bath 4-5 microinches gold.
How other people manage to make that kind of cheap jewelry, what could be the base metal and some seems to look like Rhodium , and gold plated(not dye coat).Really wonder.
Can anyone suggest me the base metal which is suitable to make imitation jewelry.

I can't really answer that question since I'm not familiar with that jewelry. Sorry. But if it is, as you say, gold plated; and it is cheap enough to imply that the gold HAS to be thin; and it still shows good durability; then it sounds like it has been titanium nitrided after the thin gold plating. But we'd need to find someone with jewelry experience to know if that's actually the case :-)

Mr.Mukesh,
The raw jewellery is made out of Brass,Copper and castings.
The platers usually do not use Micron plating bath.
This is a guilding flash bath of gold having conc. of around 0.3 grm gold.The bath is not a permenent one because as you plate a reaction takes place wherein dissolution of the base metal usually nickel takes place and the bath is rendered useless after some time.But 90% of the gold is plated out and you can afford to throw the bath and make a fresh one with out cost consideration.
The advantage of this bath is that every day you make a fresh bath and you are not worried about tech.problems usually encountered in the usual guaranteed gold bath.
This bath is not of great advantage if you do not have mass prodution.
