Amar, Ask dad if you hit real gold i.e18 carat and above and if you hit
plated gold will you not get a different sound. I think there is a
difference but not enough to make a definite judgement therefore not worth
really doing it on your own. Even then please check and revert.

Jewellery

Hi Syed Bhaiya and others,

Since my dad is into this business, I should share my opinion on this.
As far as my experience and my discussions with him goes, there is no
way to distinguish between the artificial and real or gold plated
jewellery to be specific using the touch and feel concept. Though the
weight has some sort of element while deciding, but it cannot be the
single factor while taking a call.

 Even in the case of stones, the jewelers can tell you by examining
the weight, shape and size along with other things (but for our
purpose we may restrict it to these three parameters), but that
requires two things: 1. Very good practice / accuracy, and
2. Regular touch with the market. Specially now a days due to
technological developments from a common man's prospective these
things are becoming more complex. Precious stone / semiprecious has
altogether different ways for examination purpose.

Distinguishing between mettles hcan be acheaved to an extent but that
too works when it is raw mettle.

As far as I know, no such technology in the form of assistive aids
exist to assist us in this area. Lets see what others have to say on
this.

Regards,
