Versatile 25/06/29 Slotted Stone Settings: 4 & 6 Prongs - Video Only Massive 80% Savings [yB2kfPUn]

Recorded Sunday, June 29, 2025 

Instructor: Julia Lowther

Explore the construction of 4-prong and 6-prong slotted or cut-card settings from sheet metal with expert Julia Lowther. The basic cut-card setting is a great alternative for both faceted and cabochon stones, and lends itself to bold statement designs as well as to more visually delicate and slender claw settings. A version of this versatile setting can be seen everywhere in the stone setting for the classic solitaire engagement ring. Students are encouraged to produce both samples and finished elements for jewelry applications. They can also watch and make pieces later! We will discuss a few great soldering and construction tips that apply to several soldering applications.

Participants are encouraged to work in sterling silver to create samples and finished projects, but copper or brass will work as well.

Prerequisite: Beginning Jewelry/Metals and ability to solder independently.
