Quick Summary

Gem setting is the process of securing gemstones within jewelry. This involves various techniques that have evolved over centuries. Historically, early methods focused on shaping stones and then securing them with a metal rim, or collet, which was pounded down around the gem for stability.1

Modern techniques often involve a metal ring with prongs that hold the stone, allowing for maximum visibility of the gem. For pearls, drilling was a common method for stringing or fastening them. The cutting and polishing of gemstones are crucial for their beauty and durability. Techniques range from cabochon cuts for opaque stones to intricate faceting for transparent gems like diamonds, rubies, and sapphires, designed to enhance brilliance through light refraction and reflection.12
