[QUOTE="Lecollectionneur, post: 432855, member: 8569"]Age makes a difference as a brand new one sold one year ago is for sale as second hand and doesn't interest collectors as the first produced ones, this one is an old work, the corrosion around the fixation and on the back comes from a badly down cleaning with solme liquid stay in the hollow part, typically made with standard cleaning products. What you can make for last rinsing, as we make in the ultrasonic bath at about 30° is to use a mix at 50% demineralised water and cleaning acohol, but be very careful with the flame at this temperature, always work with closed container and have a protection mask with glasses. The use of this mixture with the temperature gives a very fast evaporation and more a brilliant result than with just normal water. On GJ brooches, the clasp can be of a large grade through the years, and the finish of the pin depends from the silversmith mounting the jewel at last operation. Actually you can have exactly the same in 925 silver as on the picture by a classic seller as Bijoutil.[/QUOTE]
