Keum-Boo. These has to be done with fine silver (99.9%) as opposed to sterling silver, which has a copper component. The 22K gold leaf is burnished on with the piece warmed on a hot plate. Very cool ! The possibilities seem endless.
Tension Set Ring
This was interesting, too. This required no soldering at all, but the sterling had to be very thick to maintain the tension required. This style is a little modern for my tastes, but I like it anyways ! The stone is a faceted citrine.
