Negative space in jewelry refers to intentional open areas that define the form of the piece and create visual interest alongside the positive forms.

Question 91: A hammered finish on gold jewelry is primarily created by:

Using a mechanical engraving tool
Striking the surface directly with a hammer (Correct answer)
Sand blasting the surface with abrasive particles
Immersing the piece in chemical texturing solutions

Correct answer: Striking the surface directly with a hammer

A hammered finish is created by physically striking the gold surface with a hammer, producing a series of faceted dimples that catch and reflect light in multiple directions.

Question 92: What does the 'fineness' system of marking gold use compared to the karat system?

Fineness is used only in Asia; karat only in America
They are identical systems with different names
Fineness uses letters; karat uses numbers
Fineness expresses purity as parts per 1,000; karat expresses parts per 24 (Correct answer)

Correct answer: Fineness expresses purity as parts per 1,000; karat expresses parts per 24

Fineness marks express gold purity as parts per 1,000 (e.g., 750 = 18k), while karat expresses purity as parts per 24 (e.g., 18k).

Question 93: A ring marked 18K is what percentage pure gold?

Question 97: In gold jewelry design, what does 'scale' refer to?

The purity of the gold
The number of pieces in a collection
The relative size of design elements in relation to each other and the wearer (Correct answer)
The weight of the gold used

Correct answer: The relative size of design elements in relation to each other and the wearer

Scale in jewelry design refers to the relative size relationships between design elements and how the piece's size relates to the wearer.

Question 98: Medieval illuminated manuscripts used gold leaf in a technique called what?
