Help GG-Juwelier with a new logo

GG-Juwelier

Bruchgoldspezialist

Few words about the business:

This is about selling/purchasing points in the concept of a shop in a shop. They will be located in Austria-Europe and will invite the customers of juwelers to sell their old, broken or scrap gold.
The logo is in German and it means gold is money (Gold is Money - Juweler). The slogan means old gold specialist. It has to reflect the reliability and seriousness of the business and has to be inviting and attractive! Please, try to think out of the box and avoid trivial suggestions, such as simplified golden designs with diamonds! Your work should send a clear and effective message, be memorable and professional and suit to the distinguished, serious and prestigious profile of our business! It should definetely inspire trust.
The target audience is both European men and women, aged from 30 to 70 and from different backgrounds.

Technical specifications:

We wish to have a logo and a favicon. The logo should be in high resolution, in both transparent and in black & white background, so that it can be used for print-outs, business cards, stationery etc. Every image should not have the watermark of the designer. If you use a special font, we must know the name of the font, if you will be chosen as a winner.
Cartoons are not desired and the typing should not be kittenish in general.

The logo of Mythos should help you to get an idea of what we have chosen in the past, but should not limit your imagination. We are not interested in getting a kind of a copy of the Mythos logo. It should be something new.
The second attached file is just a draft we have made. Please, feel free to use completely different colours, fonts, backgrounds etc, as it doesn't reflect our expectations.
Good luck!
