Hi Osman and hello to you in Bosnia!

It's difficult to tell from the photos, but I think one thing that will really make a difference is to change the tumbling media to stainless steel shot. There is a mixed-media made-up of different shaped pieces for tumbling metal jewelry. I know of folks who also just use the stainless steel pin-media which works well also.

There are different types of ceramic media. Some are best used for de-burring and light metal-removal...not polishing to a bright finish. Tumbling using the stainless steel shot combined with water and dishsoap will give you a bright shiny finish on the metal. Make sure you use STAINLESS steel shot and NOT STEEL shot as the steel will rust.

I have been taking a silversmithing class for 2 1/2 years. I know that the classtroom also uses the stainless steel shot. Our instructor is a Master Jeweler, so it's pretty safe to take her instruction as the word on the subject. It is always a beautiful, shiny finish.
Just thought I would agree. :)
