Hello Paul, the item you are referencing is one of my pendants which
is titled "Citrine Repousse Pendant" (copyright 2002), from the JDPN
The half donut shaped part of this pendant was formed using the
repousse technique, raising the shape from the back of the 18kt gold
sheet while it is set in pitch (face down), using dapping punches.
You can find on repousse in the Orchid Archives if you
search for it. This technique was one of the most commonly applied
techniques in goldsmithing, in many regions of the ancient world.
Here in the west it is currently undergoing a wonderful renaissance.
Generally repousse is done with fairly thin metal, but in my
particular application I use rather thick gold sheet, from 1.25 to
1.5 mm. This makes the process more time consuming and difficult to
achieve, but it gives the substantial quality that I desire to the
finished piece of jewelry.
It is very enjoyable to do repousse, and quite frankly I find it a
bit therapeutic to pound out the metal for the pendant after the
tranquility of crocheting the necklace chain.
