Gold Design Certification Practice Test — Questions and Answers

Question 1: According to US regulations, gold-filled jewelry must contain a gold layer that is at least what fraction of the total metal weight?

1/20 (Correct answer)
1/10
1/5
1/40

Correct answer: 1/20

US regulations require gold-filled jewelry to have a gold layer constituting at least 1/20 of the total metal weight, making it more durable than plated items.

Question 2: How much gold should be in a gold filled piece to be labeled as 1/20 gold?

25%
10%
5% (Correct answer)
15%

Correct answer: 5%

The label '1/20 gold-filled' signifies that the outer layer of gold must constitute at least 1/20th of the item's total weight. This legally mandated standard translates to a minimum of 5% pure gold by weight. This significant percentage ensures the jewelry's durability and resistance to tarnish, distinguishing it from less substantial gold plating.

Question 3: Rhodium plating is most commonly applied to gold jewelry in order to:

Enhance brightness and scratch resistance of white gold (Correct answer)
Increase the karat purity of the gold
Create a hammered texture on the surface
Add a warm yellow tone to the piece

Correct answer: Enhance brightness and scratch resistance of white gold

Rhodium, a platinum-group metal, is plated onto white gold to compensate for its slightly yellow tint and to provide a harder, more scratch-resistant, bright white surface.

Question 4: Which finishing technique creates a matte, non-reflective surface by rubbing gold with fine abrasives?

Burnishing
Hammered finish
Satin/brushed finish (Correct answer)
Engraving

Correct answer: Satin/brushed finish

A satin or brushed finish is created by rubbing gold with fine abrasives, producing a soft, matte texture that scatters light rather than reflecting it.

Question 5: Which earring component secures a post earring to the ear?
