The objects were examined using optical microscopy, X-radiography and Scanning Electron Microscopy (SEM).
In addition, the elementary compositions of alloys and solder joints were investigated using air-path X-ray fluorescence (XRF), proton-induced X-ray analysis (micro-PIXE), and energy-dispersive X-ray analysis (SEM-EDS).
This preliminary study provides information about the evolution of alloy composition and the use of alluvial gold, and illustrates the Ancient Egyptian goldsmiths’ skills in working with wires, granulation and joining techniques. Les objets ont été observés sous microscopie optique, par radiographie de rayons-X et par microscopie électronique à balayage en mode électron secondaire (MEB-SE).
En parallèle, la composition des alliages et des soudures a été déterminée par fluorescence des rayons-X (FX), par analyse par faisceaux d’ions (micro-PIXE) et par énergie dispersive de rayons-X (MEB-EDS).
This had the effect of changing the golds colour slightly.
As a result rose and green gold can be commonly seen in retro jewellery along with yellow gold.

Very little jewelry from the Villanovan Era, an Early Iron Age culture dating c.
1100 BC – 700 BC, has been discovered in modern times.
The basic forms of jewellery vary between cultures but are often extremely long-lived; in European cultures the most common forms of jewellery listed above have persisted since ancient times, while other forms such as adornments for the nose or ankle, important in other cultures, are much less common.
Historically, the most widespread influence on jewellery in terms of design and style have come from Asia.
