Keum-Boo Jewelry Guide: What Is Keum-Boo?
Keum-Boo began in Korea, where artisans pressed thin gold foil onto silver. The process continues today, although modern makers often refine the steps.
First, you heat sterling silver until fine silver rises to the surface. Then you press pure gold foil into that surface, so the two metals bond permanently.
Because the bond forms through heat and pressure, the result stays stable.
This Keum-Boo Jewelry Guide highlights the value of the method. It keeps part of the silver visible, which creates a layered look and adds depth to Keum-Boo jewelry designs.
Keum-Boo Jewelry Guide: Keum-Boo vs Gold Vermeil
Many buyers compare Keum-Boo with gold vermeil. Although both include gold on silver, the techniques differ.
Gold Vermeil
Gold vermeil uses an electrochemical bath. Because of that, it forms a complete layer of gold. This layer covers the entire surface, so the silver remains hidden.

Keum-Boo
Keum-Boo relies on heat instead of chemicals. It uses pressure instead of electrical current. Therefore, the silver remains visible. The gold appears as a pattern rather than full coverage.
As a result, Keum-Boo feels more textured and more artistic.
Types of Keum-Boo Jewelry
Keum-Boo Rings
Keum-Boo rings show bold gold shapes because the foil stands out. If you enjoy textured rings, also explore Artisan Silver Rings for similar styles.
Keum-Boo Earrings
Keum-Boo earrings often look dramatic, especially when the silver is oxidized. For example, blackened silver makes the gold shine even more. For more on oxidation, see the guide from the Ganoksin Jewelry Making Community.
Keum-Boo Necklaces
Necklaces offer wider surfaces. Because of that, artists can create stronger foil patterns. If you enjoy striking designs, see Modern Handmade Necklaces for related pieces.
How to Care for Keum-Boo Jewelry
Keum-Boo pieces follow the same care rules you use for sterling silver. However, a few habits help keep both metals bright.
Wear Your Jewelry Often
Daily wear slows tarnish because friction reduces oxidation.
Remove Jewelry for Certain Activities
Take off your pieces before swimming, cleaning, or showering. These steps protect both the gold foil and the silver. For safe storage methods, also see How to Store Sterling Silver.
Put Your Jewelry on Last
Sprays and lotions can settle on metal. Therefore, add your jewelry after grooming.
Cleaning Keum-Boo Jewelry
Basic Cleaning
Use mild soap, warm water, and a microfiber cloth. This method keeps the gold bright without stress.
Deeper Cleaning
Use a baking soda paste if the silver needs extra help. For a full checklist, see How to Clean Silver at Home.
Removing Tough Tarnish on Plain Silver
Plain, unoxidized silver can soak in vinegar and baking soda. However, you must avoid this method for oxidized pieces because it can remove the black finish.
What to Avoid
Skip strong chemical dips. Instead, use gentle methods to maintain the bond and surface.
Why Keum-Boo Appeals to Collectors
Collectors choose Keum-Boo because each gold pattern looks different. For example, no two earrings or rings ever match exactly. If you enjoy other hand-worked textures, also see the article on Hammered Jewelry Finishes.
