Where can I find Silver and Gold Jewelry in Tokyo at the current market-price.

I have often travelled to places like Dubai, India… where jewelry is a very serious market and you can get silver, gold, platinum at the ongoing market rate. And as i am into jewelry investment; after shifting to Japan, I am not actually finding any such market that is so serious and real about the price structure of the jewelry (Including factors like making charges, real-time metal rates, and resale value).

I find stores and my colleagues at work buying a 10g silver ring that should cost only ~4000¥ (1g silver = 345¥ + making charges) at prices like 10,000 – 12,000, which are just over-inflated prices to exploit customers because they don’t know how these markets works.

So please help me find if there is some real deal in Tokyo or if it’s simply not a big market in Japan.
