The trend for the two-tone look has become popular and jewelers utilize many techniques to achieve this look. Keep reading for a quick overview of a few different methods. Each technique will achieve a slightly different look but sometimes it is hard to tell the differences.
Some jewelers gold plate their jewelry by using a gold pen plating machine that utilizes low voltage electricity and a chemical solution. One can “draw or paint” a very thin and precise design layer on a specific area. Care must be taken when wearing plated jewelry because the plating over time can wear off. This can easily be repaired by re-plating.
Bi-metal consists of a layer of karat gold bonded to a layer of sterling silver. It has two distinct surfaces of silver on one side with 14k, 18k or 22k gold on the other side of the sheet.
Gold-filled consists of a thick layer of karat gold bonded to a base metal using heat and pressure. While care must be taken in working with this material Gold-Filled items are affordable and will have the same appearance as solid gold and can last years.
The Keum-Boo method is a Korean technique for applying 24k gold sheet to silver and is widely used in various cultures. It can also be done in different karats of gold.
With experience in application, it offers a very distinct and controllable method of gold patterns on silver.
The approach I use for my silver and gold jewelry is a simple, but not an easy method.
I fabricate each gold design element from solid sheet and wire. For instance, I will cut a leaf shape out of solid 18k or 22k sheet or curve a solid 18k gold wire and fuse or solder it to a silver band. Even though it is extremely time-consuming I thoroughly enjoy the process.
